Features and advantages of PIT chain saws (PIT)

The mechanization of lumberjack labor is not a new invention: the canonical bearded man with an ax ceased to satisfy the growing appetites of industry and construction at the end of the 19th century. At the same time, the basic elements of a modern chainsaw were invented, finally assembling the saw chain, guide bar and light gasoline engine at the beginning of the twentieth century.

Much has changed since then, but the design of the chainsaw retains time-tested features: a two-stroke engine, a centrifugal clutch, a chain with sharp teeth rotating along the perimeter of the guide. But even taking into account the age of this mechanism, in which, it would seem, everything has already been brought to perfection, choosing a reliable and convenient chainsaw can be difficult. Well, let's try to understand what the market offers us today. We present the rating of the best chainsaws of 2022 - early 2022, and we will also tell you how to choose a chainsaw and which model is best for your home or garden.

Design features and characteristics of models

The PIT saw is easy to use and is equipped with a two-stroke engine, a feature that makes it possible to reduce the effort required when starting the engine. The anti-vibration system includes 4 shock absorbers that reduce vibration. The filter has a special casing that comes off using a rotary roller.

There is a primer for pumping fuel; its presence makes it easier to start the engine after a long break. The design is easy to maintain. There are no tools required to access the spark plug and filter. The lid lock is released manually and the lid can be easily removed. After this, clean the filter.

The chain is tensioned using a screw. After starting the device, the rotation of the chain will begin only after the operator presses the upper and lower buttons simultaneously. This is how the system protects against accidental starting of the tool.

Technical characteristics of the PIT GCS D chainsaw:

• Chainsaws of the PIT line have high power; the length of the bar is 45 cm, which will allow the summer resident to carry out work in the garden.
• The cylinder volume is 45 cm³.
• The fuel tank has a capacity of 550-600 ml, which is enough for 1-2 hours of operation.
• An oil tank with a volume of 300-400 ml is installed to lubricate the chain. This is enough for 2-3 hours of work.
• The engine is two-stroke, runs on AI-92 gasoline mixed with chainsaw oil, the proportion is 1:50.
• The housing has a hole for adjusting the fuel supply and idle speed.
• The engine starts easily if you follow the starting technology.

To start the engine, you need to pull out the choke all the way, place the tool on the floor, rest against the handle and crank the engine by sharply pulling the starter handle. It is necessary to repeat attempts until the engine starts working. After this, you need to remove the choke and start the engine.

The PIT GCS D-52 chain saw is a manual start model designed for professional and domestic wood cutting. The device has a 3 hp gasoline engine. The engine capacity is 52 cm³. The volume of the fuel tank is 0.45 l. The length of the bar is 45 cm. The number of speeds is 1. The weight of the saw is 7 kg. There is a vibration protection system.

You can see how exactly the cuts should go in the video. While
learning how to cut correctly, you should not forget about a common situation. If the tire is stuck in the barrel, it should not be jerked sharply. First you need to turn off the engine and put on the brake, then manually carefully tilt the barrel until the chainsaw pops out. To prevent getting stuck, it is recommended to place small stakes during work.

Particularly thick trees are felled only with the help of special equipment and with the involvement of professionals. Beginners should not do this themselves, since there are many felling methods, and the choice depends on various factors.

Cutting down branches

Branches are pruned only from a fallen trunk. When working, you need to exercise special care and caution, as there is a high probability of the branch rebounding.

When working, you should follow several rules:

• First of all, it is important to secure the barrel so that it does not roll. It happens that the trunk rests on just one branch; after cutting it down, the tree tilts or begins to roll.
• First, cut down the lower branches, gradually moving towards the upper ones. They begin to work standing to the left of the tree.
• When working, the chainsaw can be pressed against a thigh or tree. The branches are cut off from the top by turning the tool on its side.

• When considering how to properly cut down branches, it is worth remembering an important point. It is not recommended to use the nose part of the blade; it is better to cut with the middle and bottom part, otherwise the branches will bounce off.
• Thick branches can be cut down in sections, starting from the top. You may also need to make cuts on both sides.

If the blade is jammed, it is released as if it is stuck in the trunk: first turn off the tool, then pull the branch to the side.

Owner reviews and prices

Prices for Chinese PIT models range from 3,200 to 5,500 rubles. Reviews from the owners of this tool will help you make the right choice when buying a chainsaw.

Sergey Ivanovich, 40 years old, entrepreneur, Moscow

He opened a small enterprise for the production of wood products. The Chinese-made PIT saw helps with the work. The tool is durable and reliable, equipped with a vibration protection system and easy starting. Working with such a tool is convenient and comfortable. The noise level is low, the saw can operate for a long time without interruption.

Fedor, 45 years old, carpenter, Krasnodar

I work at a woodworking plant. The company has several PIT brand chainsaws. We purchased them at prices below market prices. These devices are highly powerful and efficient in operation.

Svetlana Aleksandrovna, 54 years old, summer resident, Tuapse

My husband recently purchased a new PIT brand chainsaw. Using this device, he cuts dry branches from trees and cuts down unnecessary dried trunks. This device is also used for various housework. The device operates without noise or vibration.

How to use a chainsaw correctly

Launching the tool is easy, but working with it can cause some difficulties. A few tips will help make the process easier and safer:

1. The saw must be held with both hands, the handle held firmly with all fingers. The left thumb should be located under the front handle.
2. You need to keep the tool closer to your body: this makes it easier to maintain control over the saw and maintain balance. In addition, in this position the hands get less tired.
3. Your legs should be wide apart and your knees bent to maintain stability. It is better to keep your back straight.

When figuring out how to cut with a chainsaw correctly, do not forget about the importance of correct movements. If it is necessary to change position, turn off the chainsaw and put on the brake. In some cases, if a long break in work is required, the tire should be covered with a casing.

Experts recommend learning to use a chainsaw on horizontal logs of medium thickness. They are not difficult to work with, and in the process it is easy to figure out how to properly handle the saw.

The only difficulty with cutting logs is choosing a blade. The thinner the log, the smaller the canvas should be. However, this is not a mandatory rule and can be ignored.

About the PIT brand

The production of PIT chainsaws is located in China. Like most modern manufacturers in our time of global production without borders, PIT uses some components from large specialized concerns for assembly. For example, PIT models have high quality carburetors from the Japanese company Walbro.

PIT is a large manufacturing concern. It has its own industrial site, where most of the components for chainsaws are made. This distinguishes PIT from pure assembly manufacturers, who simply assemble products almost entirely from other people's components.

The birthplace of the brand and the country of manufacture of PIT chainsaws is, of course, China. Some sources indicate Russia as the birthplace of the brand. Most likely, this is due to the fact that the supplier companies ordering PIT chainsaws for the Russian market are located in Russia.

Features of PIT chainsaws

According to experts, the first acquaintance with PIT models leaves an impression of good quality. Even the smallest details show the manufacturer’s responsible approach to quality.

• the factory box has a factory seal;
• each chainsaw has its own individual serial number;
• Labels and labels are not made on paper stickers or painted on surfaces, but on a specially made plastic base.

1. PIT chainsaws are equipped with “Easy Start” systems, like all the latest models from expensive, reliable brands.
2. PIT mufflers are larger than all other brands. On some models - with three rather than two nozzles. This dramatically reduces the possibility that the exhaust system will become clogged with carbon deposits over time.
3. PIT models have a screw for adjusting the oil supply to the cutting head, which is rare. Typically, manufacturers strive to simplify and reduce the cost of production by getting rid of any additional part, even the necessary one.
4. The tire is fastened in the best way today - on two (not one) studs and nuts. The plastic cover over the tire is protected from being pressed by the nuts by a metal sleeve inside the holes for the studs.
5. The chain tensioning is also done in the most convenient way - from the side, and not from the end, as in some brands, using a regular flat-head screwdriver.

Equipment

In a sealed PIT box, the buyer receives, along with the saw, a set that is standard for most brands:

1. tire;
2. chain;
3. universal screwdriver for spark plug and tire fastening;
4. instruction manual with warranty card.

In addition, the PIT buyer receives:

• second spare chain;
• measuring tank for precise dosage of oil for mixing with gasoline.

Different PIT models differ significantly from each other in layout and appearance. Some of them are estimated to be similar to the best Carver chainsaws. Others look like Hitachi.

Review of the most popular PIT chainsaws

Today there are four PIT models on sale on the Russian market. Let's look at each of them in more detail.

Chainsaw PIT GCS-52-D

Designed for home use. The most powerful option among the entire PIT range.

• power 2.2 kW or 3 hp;
• combustion chamber volume 52 cc;
• fuel tank volume 550 ml (0.55 l);
• volume of the oil tank for chain lubrication is 200 ml (0.2 l);
• bar groove width (chain thickness) 1.5 mm;
• links in the chain 72 pcs;
• weight 5.8 kg;
• 1 year warranty;
• price - about 5000 rubles.

Review: We bought it to tidy up an old garden. Throw down some of the trunks and trim off thick branches. We chose not by the name of the company or capacity, but based on how much money we had, the most inexpensive option. We recommended this model. It cuts calmly and has enough power. I don’t give it all the gas, let it run in. We are happy with the purchase.

Sergey Nikolaevich, Ryazan.

Chainsaw PIT GCS-45-D

Recommended for semi-professional use.

• power 2.0 kW or 2.7 hp;
• combustion chamber volume 45 cc;
• fuel tank volume 450 ml (0.45 l);
• volume of the oil tank for chain lubrication is 260 ml (0.26 l);
• bar groove width (chain thickness) 1.5 mm;
• tire length 40 cm;
• weight 5.6 kg;
• 1 year warranty;
• price - about 5000 rubles.

Review: Starts very easily. Literally from the second pull of the starter. The first, as required by the instructions, is done with the damper lever extended. If at the end of the jerk the engine starts to seize, the lever is pushed in and the engine starts on the second pull. Chainsaws from other manufacturers often start much worse. It works smoothly, no complaints yet.

Konstantin, Rostov.

Chainsaw PIT GCS-45-C1

Positioned as a semi-professional chainsaw. The characteristics are almost identical to the previous model PIT GCS-45-D.

The numbers in the article numbers of PIT models indicate the volume of the engine combustion chamber. For the PIT GCS-45-D and PIT GCS-45-C1 options they are 45 cc.

There is a slight difference in the volume of filling containers and weight. But there is a noticeable difference in price. From which we can assume that option C1 is of higher quality. Externally, this can be assumed already because the muffler of the C1 version has three exhaust nozzles instead of two.

• power 2.0 kW or 2.7 hp;
• combustion chamber volume 45 cc;
• fuel tank volume 550 ml (0.55 l);
• volume of the oil tank for chain lubrication is 190 ml (0.19 l);
• bar groove width (chain thickness) 1.5 mm;
• tire length 40 cm;
• weight 5.9 kg;
• 1 year warranty;
• price - about 6500 rubles.

Review: I recently bought it. In a couple of years I will be able to say something about reliability. Now it’s just the feeling – I like it. It's a pleasure to pick up and work with. It feels like everything was done diligently and well, everything was thought out. It starts up well and drives as expected. Then, perhaps, I will be disappointed, but for now this is how it is. Of the minuses, the chain most likely needs to be changed, put in a real one from Oregon or Stihl (we recommend reading why Stihl chains are popular).

Vasily, Tambov.

User questions about chainsaws

The Husqvarna chainsaw started only on choke and then stalled. I bought a new Chinese carburetor, it looked exactly the same, it started idling smoothly and started without any suction. You start sawing and after 2 seconds it stalls. If you re-gear it, it still cuts for a little while, but then it still doesn’t hold high speeds. What's the matter?

First, check the fuel filter. If OK, back out the low speed screw (L) until it starts to pick up speed normally. Since X.X will increase, reduce it with the bolt (T) that is on top.

Chainsaw McCULLOCH MAC930 CC30 KW1.2 tire 35 cm, assembled in Italy in the 90s. Piston, seals are ideal. Doesn't hold idle speed or doesn't pick up speed when you try to accelerate it, it feels like it's choking on gasoline. Gasoline is pouring from the exhaust. What is the problem and how to fix it?

According to the symptoms described, gasoline is not flowing well, probably because the diaphragm has dried out due to long inactivity. You can fill the saw with gasoline, pump it manually and leave it for a while. From gasoline, all the rubber bands should get wet and start working. If that doesn’t help, then you can pick up a carburetor from some modern Chinese saw of similar cubic capacity (for example, from Shtil). After replacement, adjust the joint with the cylinder.

If I fill a Husqvarna chainsaw with Stihl oil or any other branded oil, should I follow the proportions of 1:25 as indicated in the instructions?

If branded oil for two-stroke engines is poured, then it does not matter which manufacturer it is from. High-quality fuels and lubricants from well-known brands are interchangeable, and recommendations are only a marketing ploy. You can safely fill a Stihl chainsaw with Husqvarna oil and vice versa, observing the proportions as for branded fuels and lubricants.

Why does a chainsaw cut crookedly, that is, it moves to the side?

The tire misaligned due to uneven wear. Don't forget to turn it over when working! If the tire is already worn unevenly, only replacement will help.

Why does the Taiga 245 chainsaw only work on suction and the carburetor cannot be adjusted?

Possible options: the carburetor diaphragm is broken, the gasket between the cylinder and the crankcase, the carburetor and the cylinder is not sealed, the crankshaft seals are leaking. In Taiga 245, when air is sucked into the crankcase from the outside, the functionality of the fuel pump built into the carburetor is disrupted due to the lack of vacuum. In this case, the saw will not work. The suction closes the air supply to the carburetor. This confirms the lack of tightness in the places indicated above.

Advantages and disadvantages

The main advantage of PIT over impersonal manufacturers is factory quality control and the desire to produce high-quality goods. This can be seen from the carefully worked out details, but most importantly - from the individual number of each product and the factory seal on the packaging.

If desired, each user or service center employees can contact the manufacturer and report the product number and the nature of the problem. Based on this number and date of work, the manufacturer will take measures to improve quality. That is, in this case, the number and seal are akin to the master’s signature, guaranteeing quality.

It is important to buy PIT chainsaws exactly in packaging with a seal and number. Because there is no insurance against the appearance of Chinese counterfeits for the same Chinese brand.

Of the specific technical advantages, users note:

1. Easy and quick start.
2. Quieter engine operation due to improved muffler.
3. Possibility of adjusting the oil supply to the chain.

A commercial advantage can be considered the low price of PIT chainsaws, which is especially obvious in comparison with well-known reliable brands.

Due to the quality of chainsaws or because they appeared not so long ago, specific shortcomings inherent specifically to PIT chainsaws have not yet been noted. Except for minor faults.

The design and principle of operation of the carburetor

The main purpose of a carburetor in any internal combustion engine is to mix fuel with air in certain proportions. If they are violated, the engine starts to work incorrectly or stops completely.

Chainsaw carburetors of different brands have some differences in design, but the main components of this part, as well as the principle of their operation, are approximately the same:

• The base (body) is a wind tube with an air damper located across it. Its purpose is to regulate the air supply to the inner chamber.
• The float chamber is a container that holds the fuel mixture in a stable state.

• The atomizer is the area where air and fuel come into contact. Fuel enters the atomizer from the float chamber through a nozzle.
• A diffuser is a part that increases the speed of air flow, with the help of which the required pressure is maintained. The diffuser is located in the narrowed part of the tube.

The operating principle of the carburetor is as follows:

1. After the engine starts, the damper opens and air enters the channel.
2. The flow rate and the level of the float in the chamber are regulated by the position of the damper, due to the difference in pressure in the float chamber and the air channel.
3. Fuel from the float chamber is sucked into the nozzle and then into the diffuser. Moving through it, the air captures the incoming fuel.
4. The resulting mixture is fed into the cylinder cavities through the intake channels.

Popular faults

The only negative review about the malfunction of the PIT chainsaw that has become known is the leakage of the oil tank plug.

The exact reasons are unknown, they may be:

1. Defects in the thread of a hole or plug when molding plastic.
2. Defects in the rubber gasket.
3. Thread stripping by the user due to over-tightening.

If there is an obvious manufacturing defect, the product must be replaced. In case of your own negligence, the problem can be solved:

1. Changing the gasket.
2. By applying an oil-resistant sealant to the threads, this will increase their relief and can restore tightness.

Adjusting the PIT chainsaw carburetor

Not all modern PIT chainsaw carburetors provide for adjustment at home. They have screws for factory adjustment, but the screws may not have slots for a screwdriver or wrench. They're just naked. Walbro carburetors found on PIT chainsaws can be adjusted using adjusting screws.

This video shows a professional adjustment of a Walbro type carburetor, although the chainsaw is not a PIT.

The adjustment is carried out by measuring revolutions using an electronic tachometer. However, it can be done without a tachometer, by ear.

Video description

How to check chain lubrication is shown in this video:

• After starting and before you start using the Shtil chainsaw, the engine must run for at least a minute to fully warm up. To do this, squeeze the gas to the end.
• At the end, turn off the brake and check the lubricant supply. To do this, the instrument is brought to a light object (sheet of paper or wood) and held above it. If traces of oil appear on it, then there is enough lubrication.

Using the above method, start the chainsaw with a cold motor. If the tool has been running for some time and has not cooled down after that, there is no need to move the throttle valve.

Analogs

PIT chainsaws can take an extremely advantageous position in the market in comparison with analogues in terms of power.

• they are close in price to the cheapest models, but can be an order of magnitude superior to them in quality;
• in quality they can be close to brands of expensive brands, remaining 2-3 times lower in cost.

As a result, if this manufacturer continues to focus on quality at an affordable price, it can significantly expand its niche in the market.

PIT chainsaws are a kind of middle ground between cheap Chinese saws and expensive German ones, for example Stihl. Before choosing, the main thing is to understand for what needs the tool is being purchased. If the budget is limited and you do not plan to use the chainsaw often, then the PIT gas chain saw will be an excellent choice for the home.

Preparing for work

After choosing a suitable saw and purchasing it, you must carefully study the operating instructions. A chainsaw is a dangerous tool; working with it requires extreme care.

Preparing the saw for work consists of several steps:

• It is necessary to check the tool externally: the parts must be well secured, the body is not damaged, the tire is fixed in its normal place, the chain is inserted into the grooves and engaged with the sprocket.

• Then, in the process of preparing the chainsaw for work, you need to check the chain tension. It must be optimal: if the tension is too strong, the load on the engine will increase; if it is weak, the chain may jump off during operation. To check, you need to try to pull the chain in the middle: it should come out of the groove by a few millimeters. Then the chain needs to be turned a little - it should move freely without getting stuck. If the chain does not move or rise, the tension needs to be loosened; if the chain sags, tighten it.
• Afterwards, you need to fill the chainsaw with fuel: gasoline and oil for two-stroke engines. The ratio of gasoline and oil is indicated by the manufacturers themselves. Usually take 20 ml of oil per liter of gasoline. Both substances are mixed and poured into the tank.
• Finally, add oil to lubricate the chain. It is necessary to use only special oils - motor oils can easily damage the engine.

It is important to remember that fuel and lubricant are consumed approximately equally. It is necessary to regularly check their level and top up as needed.

About company

The PIT trademark was founded in 1996 by a group of companies engaged in the production, supply and sale of hand-held power tools and gasoline-powered equipment. At the moment, the brand is widely represented in Europe and the CIS countries, and its presence is expanding in other countries, including Russia. The instrument appeared on the Russian market in a wide range by 2009 and has already proven itself to be excellent. The advantageous difference between the company and other Chinese manufacturers is the full production cycle, from the production of spare parts to final assembly and packaging. Most competitors have production scattered across different regions of China, and even in other countries, this creates certain problems with quality control and logistics, and also affects the cost of products. The production of tools is certified according to ISO 9001, which allows the sale and use of products in almost any country in the world.

Development

Since 2010, the group has been the official distributor of the PIT brand in Russia. All main types of power tools are on sale: drills, screwdrivers, rotary hammers, welding equipment and gasoline-powered equipment, spare parts, as well as a wide range of machines for various purposes. The company is developing a dealer network in various regions, offering mutually beneficial conditions for collaboration. Our specialists are always ready to provide quality advice on any product item. There are more than 200 service centers throughout Russia, where any warranty or non-warranty repairs will be done quickly and efficiently. All decisions in our company are made promptly and in favor of our partners and clients. The main goal of our company is to take one of the leading positions in the sale of power tools on the Russian market, while maintaining high quality and affordable cost. Our company is a regular participant in the annual International specialized exhibition of tools, equipment, and industrial technologies “Mitex”. Marketing research is constantly carried out, the demand and needs of the end consumer are studied. It's no secret that consumer behavior has changed in recent years - the widespread development of lending has made them more price sensitive. If previously the key role was played by the big names of famous brands, now people prefer the optimal price/quality ratio and do not want to overpay for the name on the label. Therefore, the brand is the best choice of power tools for both professionals and amateurs.

Production

High-quality combined materials and modern technologies are used in the production of products. The use of high-strength light alloy metals reduces weight and increases the service life of the tool; multilayer polymer plastic guarantees additional protection from shocks, falls and other physical impacts on the product. The ergonomics of the tool provide more comfortable working conditions; silicone inserts in the grip areas help reduce vibration. Until 2012, the manufacturer placed the main emphasis on quality, although sometimes this was partly to the detriment of ergonomics. In 2012, a breakthrough was made - a new black line was developed and launched, and here the closest attention was paid to ease of use. The quality of products has also reached a new level; in the “black” line, the armatures of electric motors are already filled with a compound, which significantly increases their protection from dust and debris and helps to extend their service life. The new products are much more reliable, more convenient and “user-friendly” than their predecessors, and have already taken their rightful place in the Russian market.

Signs of incorrect carburetor operation

Carburetor malfunction may be due to clogged intake ports and incorrect settings.

Signs of incorrect operation:

• Gasoline consumption is increased, thick white smoke comes out of the exhaust port;
• the engine runs with difficulty, with a characteristic sound;

• the engine starts and stalls or does not start at all;
• the chainsaw “shoots” at the carburetor.

Is adjustment always necessary?

Before interfering with the factory settings of the carburetor, make sure that the incorrect operation of the chainsaw is associated with it:

First, make sure that there is a fuel mixture in the tank of the saw that does not want to start and that it is entering the carburetor.

If the tank is full, check the fuel line. Disconnect the tube from the carburetor and perform pumping. If everything is in order, gasoline will spit out in accordance with the manufacturer's standards.

Weak flow indicates a clogged channel or fuel filter. In this case, it is enough to clean the fuel pipe and replace the filter.

Incorrect operation of the tool may be due to an overfilled chainsaw tank. In this case, smudges will be visible under the crater cover. If they are, check the connection of the fuel pipe to the carburetor. It is sometimes squeezed out when screwing on the cap of an overfilled tank. The engine may not start for this reason.

The reason for poor chainsaw performance may be the quality of the oil-gasoline mixture. If you do not drain the residue and leave the instrument in storage for more than 2 weeks, the processes of resin formation and polymerization of the components will begin to occur in the tank. This can cause carbon deposits to form on the piston, rings and cylinder liner. Therefore, always prepare the mixture immediately before work in the required quantity.

If the fuel quality is fine, the chainsaw engine may not start due to clogged fuel and air filters:

To diagnose the fuel filter, disconnect the gasoline supply channel from the carburetor and pump fuel. If there is little or no pressure in the pipe, disconnect the filter.

Before doing this, empty the tank of the mixture and remove the filter element itself. A clogged replacement cartridge can be cleaned, but it is best to replace it with a new one. When using the tool in dusty conditions, cleaning should be done regularly.

Remove the air filter carefully so that dust accumulated on its surface during operation does not get into the carburetor: this may require expensive repairs.

After disconnecting the cartridge, thoroughly clean it of accumulated dirt and wash it with detergent. Then dry it and carefully put it back in place.
