Where do they sell fake STIHL chainsaws?

They can sell you a copy of the STIHL MS 660 chainsaw at shopping centers, in country houses and even in the courtyards of your home. Prices start at $100 and depending on your bargaining ability, can drop to $50.

As a rule, scammers use the same story:

  1. They used chainsaws to pay wages at a construction site or factory.
  2. We bought a stolen shipment cheaply.
  3. It was already purchased, but friends or mother-in-law gave me five more pieces.
  4. You need to drink or urgently need money.
  5. Lots of fakes on message boards.

If you need a chainsaw for a couple of days, and you are not going to cut down wood on an industrial scale, then STIHL MS 660 chainsaw will be very useful to you. The Chinese fake, although of worse quality than the original, is quite capable of “cutting” wood; in ancient times, people coped with more meager tools. You don’t mind dropping it, throwing it, catching nails, etc. You can pour anything into the tank as long as it burns, and after it breaks, throw this chainsaw into the attic and forget it like a bad dream.

When demonstrating the operation of the product, it seems to you that the saw is good. This illusion is due to the fact that sellers fill the tank with pure gasoline. After the performance, the resource of the “unfinished business” is reduced by 50%. If you bought into the trick and purchased it, then use the saw as is, with the fuel that the seller filled in.

Basic configuration, equipment, country of assembly and production

The basic package of the stihl 660-ms saw includes:

  • saw part (represented by a chain, sprocket and bar);
  • chainsaw body with engine and fuel tank;
  • owner's instructions;
  • warranty document, usually found in the manual for the technical device;
  • chain saw chain tension screw.

A detailed list of components and parts of the stihl 660-ms chainsaw can be found in the instruction manual. The country of assembly and production of the original Shtil 660-ms chainsaw is the USA, since the company's production facilities are located in this country. Germany is considered the birthplace of the brand.

On the domestic garden equipment market you can often find analogues or counterfeits of the stihl 660-ms chainsaw model, the documentation for which indicates the country of origin is China. Note that the Chinese analogue of the original Shtil 660-ms chainsaw is not the original. However, taking into account the reviews of the owners of such “copies”, it can be noted that the Chinese copy is quite suitable for everyday use.

The original will cost about 29.5 thousand hryvnia (probably higher, since a single price for the model has not been established). The Chinese equivalent will cost about three times less.

The fake Shtil 660-ms chainsaw is not equipped with additional accessories, like the original. Some online stores may offer customers original accessories for original stihl devices as a bonus. How much an original chainsaw will cost depends on whether the product in front of you is a branded product or a fake.

To throw away or not

There are situations when a person did not keep track and took a fake. Such purchases are made by hand, in spontaneous markets, as well as at dubious points of sale.

You understand that no one will return your money. And you can’t count on the chainsaw being returned.

In front of you was a Chinese copy. Question. What to do with her now? I don't recommend throwing it away. Its characteristics are enough to perform simple tasks. Yes, the original is better in all respects. But the Chinese analogue will justify its money. Suitable for simple work on the site or in the country. Self-repaired. Fortunately, buying spare parts and consumables is not a problem.

Purpose and technical characteristics

Shtil MC 660 is a chainsaw for professionals. Its price immediately makes it clear that it is intended for those who make money with it, because... it is indecently high compared to the price of household chainsaws. But don’t think that Calm 660 is not worth the money that sellers are asking for it. Buyers pay for quality, high power, huge resource, reliability and unpretentiousness.

As of today, Stihl 660 has already been discontinued because... instead, a more modern model Shtil 661 is produced, but the chainsaw can still be purchased from an authorized dealer.

The purpose of this chainsaw is specific, because its power allows you to buck the trunks of large trees and work on mobile sawmills such as “Logosol” or “Murka”.

Below is a video about the use of the 660 model calm in a mobile sawmill.

The saw has a power of 7.1 hp and weighs more than seven kilograms. Due to its large weight and power, this model is not advisable to use for trimming branches or during construction work; it is needed specifically for felling and bucking.

As standard, the chainsaw was supplied without a saw set, which means the buyer has the opportunity to choose the required bar length and chain design.

User manual

The instruction manual contains complete information about the tool and introduces the new owner of the saw to the features of its use and operating techniques.

The instructions consist of the following sections:

  1. The device of the petrol saw “Shtil” MS-660.

Device

What components does the Stihl ms-660 chainsaw consist of? We invite you to familiarize yourself with the detailed diagram of the “Calm” chainsaw:


Stihl ms-660 chainsaw device

Preparing the Stihl MS-660 chain saw for use

Before starting operation, according to the instructions, you must:

  • assemble the saw according to the instructions;
  • prepare and fill in the fuel mixture and lubricating oil;
  • check the tension of the fasteners;
  • adjust idle speed and lubrication supply to the chain.

The ratio of fuel to oil is 50/1 (for 5 liters of fuel there is 100 ml of oil). The manufacturer recommends using original Stihl oil for two-stroke engines and AI-92 unleaded gasoline.

Running in the MS 660 Stihl chain saw

The German quality of the “Calm” chainsaw requires the use of this tool without special running-in; idling for more than 10-15 seconds is especially harmful - carbon deposits appear on the spark plug.

For saws of this brand, running-in means the following:

  1. A gentle mode of operation not at full power of the power plant for a time sufficient to burn 4-8 full tanks of the fuel mixture.
  2. The first hour of operation consists of cycles: work - 2 minutes, idling - 10 seconds, rest.
  3. A properly prepared mixture of original Shtil oil and AI-92 gasoline in a ratio of 1/50.

Maintenance

Before starting work:

  • checking the chain (sharpening);
  • chain tension;
  • checking the tension of fasteners;
  • pouring flammable mixture and oil;
  • checking lubrication;
  • idling.

After use:

  • the chain weakens;
  • cleaning the saw from wood residues, dust and dirt;
  • filter cleaning;
  • monitoring the condition of the saw set (tires, chains, sprockets), replacement, sharpening, repair if necessary.

During scheduled inspections, idle speed is adjusted, the carburetor and filters are cleaned, and do-it-yourself repairs are feasible.

Malfunctions and repairs

We list the typical problems with the Stihl 660 chain saw.

Chainsaw “Calm” does not start:

  • the flammable mixture has run out;
  • fuel lines are clogged;
  • there is no contact on the spark plug;
  • I/O wire is broken;
  • the pump does not pump fuel;
  • the ignition is not configured;
  • the candle was flooded;
  • the candle is smoked or burnt out.
  • The saw does not develop speed:
  • carburetor clogged;
  • the spark plug needs to be replaced;
  • The spark plug needs to be cleaned from carbon deposits.

The chainsaw stalls at idle. The reason is that the carburetor settings have gone wrong.

Design features of the Chinese fake Shtil

Fake chainsaw Stihl MS 660

The Chinese version of Shtil MC 660 is very different from its original brother not only in technical parameters, but also in appearance. You can evaluate the power and reliability of a Shtil chainsaw only by putting it into working condition. If this is not possible, you need to pay attention to several details that literally catch your eye.

In the Chinese version, the starter housing differs from the original. In the German chainsaw, the oil and fuel tank caps are made to fit a combination screwdriver included in the package. In the Chinese version they are convex.

You can distinguish a fake by the air filter cover. It opens with a screw, which in the fake version is located on top. Probably, in this case, the package will not include a proprietary instruction manual.

Other distinctive characteristics of Shtil

It should be noted that you can purchase Stihl 660 in Russia only from official dealers of the company. You cannot find such equipment on the market. At the buyer's request, the official representative is obliged to provide a quality certificate made in gray color.

Each original instrument is equipped with a serial number located in three places:

Chainsaw "Stihl" - original and fake

  • on the body under the muffler;
  • on the packaging box;
  • in the original warranty card.

All three numbers must be identical.

On each link of the original saw chain there is the letter S, which is absent on counterfeit products. But the main distinguishing feature is the price. The cost of the original Shtil chainsaw varies between 43-60 thousand rubles. You can buy a Chinese fake Shtil 660 by paying no more than 10 thousand rubles.

Main differences

Most often found on the market is a Chinese copy of the Shtil 660 petrol saw, the most powerful and best-selling model. The analogue from China has an unusually low price, which attracts most buyers.

The original Stihl 660 chainsaws have long been removed from the production line. Model 660 was replaced by an improved modification with the index 661. Therefore, the new chainsaw of the 660th modification can only be purchased from China.

The Stihl MS 660 has become the most frequently copied model due to the fact that the original has standard dimensions and features for a budget chainsaw. Therefore, Chinese models can easily be made into doubles of a popular brand by changing their appearance.

The original model has a curb weight of 7 kg and a power of 7 hp. With. A copy from China may have the same mass, but have a smaller engine. Therefore, the original model is used for professional purposes, and the Chinese one is used only in domestic conditions, since it does not have enough traction to work in difficult conditions, as well as the quality of assembly and workmanship.

The main differences between the German Stihl 660 and a similar Chinese-made model:

  1. The original comes with proprietary instructions in several languages, one of which is Russian. The quality of the translation is excellent.
  2. The copy is colored paler.
  3. The original version has a unique starter design that cannot be faked.
  4. The German version of the chainsaw has tank caps with a combination mounting screw (screwdriver included). The Chinese version is equipped with a simpler fastener for a standard Phillips screwdriver.
  5. On the original version, the serial number is located on the body under the muffler.

Advantages and disadvantages

Despite its Chinese origin, Shtil 660 has undeniable advantages:

  1. Low price for a new unit with a warranty period.
  2. The original Shtil 660 model is not produced, but its analogue from China is sold in stores.
  3. With careful use on light work, it can last much longer than its warranty period, but it is not recommended to use a Chinese-made saw to work with dense or sticky wood.

Chinese Shtil chainsaws are produced in different factories, so the quality of their workmanship may vary. Some models will work for several days and even hours, and some will only be slightly inferior in resource to the German version.

The main disadvantages of chain saws from China:

  1. Unreliable and weak clutch mechanism.
  2. Weak starter return spring, causing the starter cord to retract poorly.
  3. The air filter housing is made of fragile, cheap plastic.
  4. The saw bar does not perform its functions well; it is recommended to replace it immediately after purchase.

Differences between a branded chainsaw and a high-quality fake

Unfortunately, a high-quality original has become a model for the production of lower-cost, second-rate counterfeits, which are sold under the trademark of a well-known brand.

The fake largely copies the appearance and design of the basic STIHL MS 660 model, but is inferior to it in basic operational functions and characteristics.

Experts recommend purchasing tools from official dealers and only if you have a special certificate.

In appearance, the fake Shtil is different:

  • rough casting of the engine crankcase;
  • lack of a sticker with a serial number;
  • with a STIHL sticker on the sprocket cover instead of an embossed lettering.

China supplies Russia with cheap spare parts, the only advantage of which is their lower cost. Parts and components made from low-quality materials produce less than half of their required service life.

Repairs performed using cheap spare parts usually result in additional costs to eliminate undesirable consequences.

About the manufacturer Stihl

In the early twenties, the stihl company was born, the head of which was the unsurpassed engineer A. Shtil.
In the first years of its activity, the company was exclusively engaged in the production of steam boilers and washing machines. But apparently this was not enough for the manufacturer and chain saws began to appear from his machines. Today, this manufacturer is represented by a huge company, which consists of more than thirty enterprises located throughout the globe. The manufacturer began to produce motorcycles taking into account the fact that these products will serve perfectly for consumers, both for construction work and for gardening and household needs. And the most important thing that I would like to emphasize is that chainsaws of this brand are the best and most popular all over the world.

Chainsaw Shtil 660 is democratic and accessible. As a rule, the price of the Chinese chainsaw Shtil ms 660 ranges from 3100 to 5500 rubles. To see the rating of chainsaws for the dacha, go here.

To sum it up...

Undoubtedly, every owner will be happy with this kind of purchase, since this technical “giant” will not only help you cope with construction or agricultural concerns, but will also cost you at an affordable price.

Do not doubt that if you choose a chainsaw from this particular manufacturer, you will not regret your choice for a second, since this tool will pay for all its costs over the years of its operation. Today, the price of a stihl 660 chainsaw (China) starts from 3,000 rubles or more. If you are interested in Russian-made chainsaws, go here.

If you have a replacement attachment for your Stihl chainsaw, then you can do anything.

STIHL MS-660: how to distinguish a fake from the original?

On the territory of the Russian Federation, the right to sell official Shtil products is granted exclusively to legitimate dealers. It follows from this that it is impossible to buy an original saw in spontaneous markets and from dubious private traders. Official representatives have a certificate made in gray color, which must be provided upon the first request of the buyer.

The instrument has a sticker with a serial number, which is duplicated on the plastic case under the muffler. In addition, this index is indicated on the packaging box. All three numbers must match.

The tire has one large hole. How to start a Stihl chainsaw, starting a Stihl chainsaw, how to properly start a Stihl 180 chainsaw first start-up video original stihl ms 180 chainsaw. Counterfeits often have an additional small socket, supposedly intended for lubrication. Chinese fake 660 original stihl ms 660 and compare with 660 – chainsaw for. However, this is a deception - the manufacturers of the original modification provided a lubrication unit with a reserve of oil, which is quite enough for the entire period of use.

In addition, the standard chain has the letter S on each link, unlike counterfeit copies. The original model uses a minimum of stickers (there are ones on the handle where safety rules are written). The main STIHL logo cannot be glued on.

Package

It is difficult to distinguish the packaging, since the level of printing is high. Counterfeit saws are packaged in exact copies of the original boxes. You can distinguish them by the information plate attached. If there are several saws in front of you, compare these plates and the numbers on them. At a minimum they should be different. Each number is unique.

Please note that there is a unique serial number on the box. All saws are manufactured in factories in China

There is one visual difference between a fake Stihl saw box and the original one - the fake does not have a pronounced white stripe around the logo and along the entire length of the box.

Owner reviews

Of the three Shtil 660 chainsaws purchased last year, one is already temporarily idle. Due to an oversight, the sawyer worked on pure gasoline. The service technicians promised to help, but the cost of repairs seems to cost a pretty penny. The equipment is modern in all respects, but too expensive and requires professional maintenance and proper operation. Unfortunately, the skills and approach to work of our specialists are at the level of the year 2000. Fedor Egorovich

I worked on the new saw for only one shift, then the new Shtil 660 was transferred to reserve until better times, and my rather worn-out Husqvarna was temporarily returned to me. What was especially memorable about the Shtilev saw was its good grip, a large power reserve, the machine, in run-in mode, saws wood with a diameter of 55 cm at 70-75% of the maximum speed. If I get my Shtihl back, I will install a 16-inch tire, which has better maneuverability and less load on the engine. Vasily Efimovich

I was lucky to participate in a regional lumberjack competition. He was not among the top three winners, he took an honorable 4th place, but he was convinced of the unique capabilities of the new models of the Shtilev brand. The Shtil 660 chainsaw is quite heavy at first glance, but this is not significant. The main thing is a smooth ride, excellent balance, almost zero vibration level, and comfortable handles. I looked at the characteristics on the Internet, if not for the high cost, it would be the best option for the wood burning business. Gorik

Technical characteristics of the saw

This kind of chainsaw is simply irreplaceable when working with sawing large tree trunks, and is also great for harvesting wood from hard structures.
The STIHL MS 660 is a true professional that embodies sophistication and practicality thanks to its design. Today, millions of consumers use this tool and unanimously speak about its undeniable advantages. So, let’s first get acquainted with exactly what features this “giant” of technology has:

  • First of all, I would like to emphasize that this tool is quite strong, powerful and capable of coping with the most difficult loads;
  • secondly, an important advantage is that the chainsaw runs on gasoline; it is this feature that allows you to work with it regardless of whether there is a power source nearby;
  • This tool is equipped with a unique system, namely anti-vibration. The important thing is that today only a few models can boast of this kind of individuality. In addition, this feature allows you to reduce the degree of hand fatigue during work, since it is no secret that strong vibrations become too heavy during work. Anyone who has experienced similar activities will undoubtedly understand without explanation. Moreover, the stress on your hands in the form of vibrations causes poor blood circulation, and this can negatively affect your health;
  • chain inertia brake , which is designed to protect your hands in case there is a strong kickback when pressing the protection (front). This mechanism stops automatically and almost immediately. This feature allows you to maximize your safety while operating the tool;
  • Important is the presence of chain tension, namely the side tension, which also serves as your kind of protection from unforeseen situations. There is a screw (tension) on the side of the chain sprocket cover. This feature protects your hands from dangerous elements on the saw, for example, such as a chain that is quite sharp and a stop with a serrated surface. See how to sharpen a chainsaw chain with a grinder here.
  • The saw of this model is equipped with a valve (decompression), the main task of which is to remove the unnecessary part of the mixture located directly in the cylinder when you start the engine. This kind of advantage allows you to significantly reduce the effort when pressing the cable (starter), which is directly responsible for starting. In addition, this feature will not only make your work easier, but also reduce wear on the starting system itself;
  • The manufacturer has supplemented this model with a fairly practical lubrication system, which in detail can be said to measure the required amount of lubricant on the chain and spikes, literally down to the drop. Compliance with the ratio of gasoline and oil for a chainsaw is very important in order to save money. The correct ratio is the reason that you will consume less oil, well, fifty percent, that’s for sure. Chainsaw chain oil can be purchased at any specialty store.

Now let's talk directly about the technical characteristics of this model. So:

  • the tool is equipped with a powerful engine with a total volume of 91.6 cm2;
  • instrument power – 5200 W;
  • total weight – 7.3 kg;
  • the length of the bar on the chainsaw is about 63 cm;
  • device chain pitch – from 3 to 8 cm;
  • the tool is equipped with two tanks - oil and fuel with volumes of 825 and 350 cm2;
  • idle speed – 2500 rpm;
  • maximum speed – 13500 rpm;
  • vibration level – 7.0 m/s2;
  • sound pressure level – 101 dB;
  • sound power level – 109 dB.

The cost of the saw corresponds to the manufacturer's stated characteristics.

Other characteristics of the Stihl chainsaw

This model of Stihl chainsaw has a number of advantages that ensure simplicity and ease of use.

Gas engine. The chainsaw runs on liquid fuel, ensuring independence from the power source.

Decompression valve. The decompression valve ensures the free release of part of the compressed mixture from the cylinder when the engine starts. This feature helps reduce the force on the starting cable when starting the engine, prolonging the performance of the starting system.

Device Stihl MS-660

Compensator. This element was developed by Shtil and is designed to adjust the carburetor. With its help, it is possible to ensure stable engine power, reduce fuel consumption and extend the service life of the air filter.

Possibility of regulating the supply of saw chain lubrication. The Stihl 660 chainsaw can be equipped with tires of different lengths and equipped with various variations of saw chains. Therefore, during operation it is necessary to regulate the supply of lubricant, which will reduce its consumption.

One lever control. All functions, including turning the engine on and off, as well as warm and cold starts, are provided by pressing one lever.

Starting handle with shock-absorbing element. This feature allows you to reduce kickback that occurs during engine starting.

Security

Operator safety is ensured by certain design features of the chainsaw.

Appearance of Stihl MS-660

Anti-vibration system. It is no secret that during the process of sawing wood, most models of chainsaws emit strong vibration. It causes hand fatigue, and subsequently circulatory problems. This model is professional, and therefore the manufacturer has equipped it with an anti-vibration system, which significantly reduces the intensity of vibration.

Inertial chain brake. This structural element ensures safety during work. The brake is activated when there is heavy kickback or when the front hand guard is pressed.

Lateral chain tension. This is another design feature that increases the safety of the equipment. The chain tension is adjusted through a screw located on the side and protected by the chain sprocket cover. This arrangement eliminates the possibility of the worker’s hands coming into contact with the sharp chain and gear stop.

What is the price

The Chinese-assembled product, the Stihl MS-660 chainsaw, is highly popular for its reliability, safety and ease of use. Users note the low level of noise and vibration during operation of the unit, long service life and the ability to operate in winter conditions. A significant disadvantage for many professional lumberjacks and land owners is the price of the tool and spare parts for it. Sometimes you have to wait a long time for the necessary parts, which negatively affects the logging process.

A new factory-installed product costs between 70,000-75,000 rubles. The variation in cost is determined by the buyer’s place of residence, the status of the trading organization and the choice of method of delivery of the goods. Used tools in good condition can be purchased cheaper. They offer to buy it for 50,000-65,000 rubles, depending on the condition and degree of wear. Offers indicating a lower price should be rejected. There is a high probability of buying a fake that will not last long.

Do-it-yourself adjustment of the Stihl MS 660 chainsaw carburetor

All carburetors on Stihl MS 660 chainsaws are factory tuned at equipped stands. This ensures the best operating parameters of the internal combustion engine in all modes. Settings are rarely lost. Before making adjustments, you need to make sure it is necessary. Deterioration of internal combustion engine performance may be caused by other reasons:

  • The air filter is clogged.
  • The spark extinguishing grill and the muffler outlet pipes are clogged with carbon deposits.

If there are no problems with them, or they have been eliminated, and the internal combustion engine is not working normally, begin adjustment.

The carburetor of the Stihl MS 660 chainsaw has three adjusting screws:

  • LA for idle speed adjustment.
  • H for adjusting fuel supply at high speeds (main screw).
  • L to adjust the proportions of fuel and air (mixture quality screw).

Screws L and H are located next to each other, LA is located at a distance from them. All of them are marked on the body.

What is needed for adjustment

To access the adjustment, simply remove the top housing cover and the air filter. Therefore, the only tool required is a screwdriver for the slots of the adjusting screws.

To professionally adjust the carburetor, you will need an electronic tachometer. It accurately indicates idle and maximum speed. Idle speed of the Stihl MS 660 chainsaw is 2,500 rpm, maximum speed is 13,000 rpm.

Without a tachometer, the quality of carburetor adjustment is determined by ear and by the actual operation of the chainsaw’s internal combustion engine.

Standard or basic adjustment

Screws H and L are tightened clockwise until the end, counting the number of revolutions made. Their number is written down or remembered. If the carburetor adjustment fails to start the engine, this data will allow you to return to the original factory settings.

  • Screws H and L are unscrewed back counterclockwise, each by 1 turn.
  • Start the engine and check its operation by ear or with a tachometer.
  • If the speed drops (chokes) when you press the throttle, screw H is unscrewed another 1/4 turn.
  • If, when you press the throttle, the engine runs as if idling, tighten screw L 1/4 turn.

Each Stihl MS 660 chainsaw that has been in operation for some time has its own characteristics, including the compression ratio in the cylinder. Therefore, the setting is individual. By turning screws H and L by 1/4 - 1/3 turns in one direction or another, optimal operation of the chainsaw engine is achieved at medium and maximum speeds.

Current setting

Experienced operators may notice during their work that the internal combustion engine of the chainsaw has begun to work worse. Sometimes it is enough to turn the screws H and L alternately in one direction or another by a small step of 1/5 - 1/6 of a turn and immediately check the result of the carburetor adjustment in real operation. This is one of the easy ways to achieve good tuning.

The video material contains information on how to adjust the carburetor of a chainsaw and check the result of the adjustment.

Idle speed adjustment

This is done using the LA screw.

Adjustment is required if the engine stalls at idle - few revolutions, or the chain spins - many revolutions.

The speed is reduced by tightening the LA screw counterclockwise until the chain stops, then unscrew it back 1/5-1/4 turn.

Adjustment with the LA screw is almost always required after adjusting the L screw, which also changes the ICE operating parameters at idle.

Screws LA and L regulate idle speed in fundamentally different ways. L changes the quality and quantity of fuel supply through calibrated holes. LA is called "jumper" because it affects the throttle position at idle speed.

Chinese version

Chinese Calm 660 is very different from the original in technical characteristics and appearance.

An experienced craftsman will determine at first glance that it is a fake. For those who do not understand gas tools, we recommend immediately paying attention to such details as:

  1. The starter housing is clearly different from the original;
  2. The oil and fuel tank caps, in the original saw, are made to fit a combination screwdriver, which should be supplied with the saw. In the Chinese version, the lids are convex and unsightly;
  3. An air filter cover, the screw of which is located on the top, and not on the back, like the real Shtil 660;
  4. The original saw always comes with a proprietary instruction manual.
  5. Although the colors of the fakes imitate the real ones, they are still not so bright and beautiful.

The original Stihl chainsaw always has a serial number. It is located on the body, immediately below the muffler. The number is also duplicated with a small sticker; it is also indicated in the company warranty card.

Upon closer inspection, you will notice that the Chinese version has a smaller volume and, accordingly, power, and the parts are made of poor quality and poorly fitted.

In fact, a counterfeit can be sold under any brand. In order for a Chinese saw to turn from Shtil to Husqvarna, careless manufacturers only need to change the sticker on the starter, and the color of the chainsaw may remain the same.

Now you know how to distinguish a fake, let's figure out what to do if you bought it.

Main differences

Most often found on the market is a Chinese copy of the Shtil 660 petrol saw, the most powerful and best-selling model. The analogue from China has an unusually low price, which attracts most buyers.

The original Stihl 660 chainsaws have long been removed from the production line. Model 660 was replaced by an improved modification with the index 661. Therefore, the new chainsaw of the 660th modification can only be purchased from China.

The Stihl MS 660 has become the most frequently copied model due to the fact that the original has standard dimensions and features for a budget chainsaw. Therefore, Chinese models can easily be made into doubles of a popular brand by changing their appearance.

The original model has a curb weight of 7 kg and a power of 7 hp. With. A copy from China may have the same mass, but have a smaller engine. Therefore, the original model is used for professional purposes, and the Chinese one is used only in domestic conditions, since it does not have enough traction to work in difficult conditions, as well as the quality of assembly and workmanship.

The main differences between the German Stihl 660 and a similar Chinese-made model:

  1. The original comes with proprietary instructions in several languages, one of which is Russian. The quality of the translation is excellent.
  2. The copy is colored paler.
  3. The original version has a unique starter design that cannot be faked.
  4. The German version of the chainsaw has tank caps with a combination mounting screw (screwdriver included). The Chinese version is equipped with a simpler fastener for a standard Phillips screwdriver.
  5. On the original version, the serial number is located on the body under the muffler.

Advantages and disadvantages

Despite its Chinese origin, Shtil 660 has undeniable advantages:

  1. Low price for a new unit with a warranty period.
  2. The original Shtil 660 model is not produced, but its analogue from China is sold in stores.
  3. With careful use on light work, it can last much longer than its warranty period, but it is not recommended to use a Chinese-made saw to work with dense or sticky wood.

Chinese Shtil chainsaws are produced in different factories, so the quality of their workmanship may vary. Some models will work for several days and even hours, and some will only be slightly inferior in resource to the German version.

The main disadvantages of chain saws from China:

  1. Unreliable and weak clutch mechanism.
  2. Weak starter return spring, causing the starter cord to retract poorly.
  3. The air filter housing is made of fragile, cheap plastic.
  4. The saw bar does not perform its functions well; it is recommended to replace it immediately after purchase.

Chainsaw Stihl ms-660

The Stihl ms-660 chainsaw is a professional tool that allows you not only to cut down trees, saw trees, saw boards, but also to cross-cut very large trunks, as well as use the saw to work on mobile sawmills such as “Murki” or “Logosol”. The basic package of the device does not include a saw set. This allows the new chainsaw owner to choose a tire and chain variation to suit himself and his needs.

The Shtil MS-660 chainsaw weighs 7.3 kg. and has the following characteristics: equipped with a high-performance carburetor two-stroke engine of Stihl’s own production, the power of the power plant is 7.1 liters. With. Overheating protection is air, manual starting from an inertia starter, ignition system is contactless. The launch control is carried out with one lever (both cold and hot). A decompressor is built in to make starting easier. If necessary, the inertia chain brake will instantly stop the unit.

The carburetor is a diaphragm carburetor with a built-in compensator, which allows you to level out the power of the power plant and ensure almost complete combustion of the fuel-air mixture, resulting in cleaner exhaust. The structure of the carburetor does not allow the chainsaw operator to independently adjust the engine speed, but it does allow the idle speed to be adjusted, at which the chain should not move. There is a heated carburetor, which is effective during cold weather.

The chain tension is lateral, simplified, with maximum protection for the operator’s hands. To protect the engine from contamination, a reusable air filter is provided. Lubrication of the cutting element at specific points saves up to 50% of lubricants. Anti-vibration protection of the handles takes care of the operator’s health.

Chain selection

Recommendations for completing the saw set are set out in the instructions. In any option, branded chains and guide bars are preferred, which in length correspond to the drive power and the nature of the work to be done.

A chainsaw chain is links connected by rivets. The links contain teeth and pushers. Saw chains vary in tooth thickness, tooth shape, link pitch and profile height. It is not recommended to install chains on a chainsaw with a pitch different from the standard one for a particular model.

There are chains specifically for frozen wood - with soldered teeth. However, in soft wood such a chain will quickly become dull.

Chains vary in length, you need to choose according to the tire. The new chain will stretch a little during operation, so it is necessary to regularly tighten it with a special screw on the bar.

The equipment must perform certain tasks and have sufficient power and maneuverability to do so. You should select equipment with the necessary parameters for these tasks:

  • Cutting speed;
  • Safety;
  • Vibration protection;
  • Power, weight;
  • Material, type of chain;
  • Additional accessories.

Particular attention should be paid to anti-vibration mechanisms and security systems. The equipment has significant weight, high speed of chain rotation, which can cause the phenomenon of kickback

An inertial brake mounted with a drive guard on the left hand side ensures safe operation of the saw.

Additionally: Chainsaw Shtil 660: Chinese version

In simple models, the role of the vibration-absorbing structure is played by a set of rubber gaskets installed between the body of the product and its handles. Representatives of the newer release are designed on the principle of a counterweight: the motor of the device is distant from the handle to the fuel tank.

Household models of Stihl chainsaws are equipped with low-profile chains with a 0.325-inch pitch. This ensures they operate with the lowest level of vibration. However, due to this design, the equipment has lower productivity. The more powerful tool features 0.404-inch chains.

Particular attention should be paid to the device's headset. Sprockets, chains, and tires of the drive sprocket must be manufactured by the same company, which will ensure their smooth operation

There are narrow, flat, lightweight tires on replaceable heads. The first ones are installed on household instruments, the second ones equip semi-professional models, and the third ones ensure stable operation of professional devices.

Other characteristics

If you want to know how to distinguish a fake STIHL chainsaw, you should familiarize yourself with the typical characteristics of the MC-660 model. The following are the features of a German-made tool:

  • Classification group – high-power chainsaw for professional activities.
  • The effective volume of the power plant (cubic cm) is 91.6.
  • Power indicator (kW) – 5.2.
  • Motor power (hp) – 7.1.
  • Weight (kg) – 7.3.
  • The ratio of mass and power of the unit (kg/kW) is 1.4.
  • Operating chain type: Oilomatic Rapid Micro at 3/8 pitch.
  • Tire size (mm) – 500.

If you decide to purchase a STIHL MS 660, how to distinguish a fake, the price of which is sometimes comparable to the original? Firstly, this is a heavy instrument in every sense, weighing more than 7 kilograms and with a power of over seven horsepower. The saw can be used in industrial workshops, with continuous operation over a long period.

This unit costs at least 45 thousand rubles in retail sales. The fake copy has similar dimensions and weight, but the power rating is half as much, and the duration of continuous operation is significantly lower, plus the insufficient strength of the body and working parts.
