Husqvarna 445e ii chainsaw review. Description, technical specifications and user reviews

How to start a chainsaw correctly: instructions

Let's look at the main steps that need to be followed in order to properly start the Stihl chainsaw.

• Before starting, the chain brake must be activated. It is activated by pressing it forward (as shown in the photo).
• Remove the protective cover from the tire.
• If the model has a decompression valve, it should be set to the on position, which will make it easier to start the tool’s motor.

• Press the fuel pump to reduce the number of pumps and make starting easier.
• The combination lever must be turned on in cold start mode. To do this, you need to lock the gas lever and press the combination lever all the way down.
• Before starting the system, it is necessary to ensure a level surface. In this case, the cutting part must be at a distance from the ground, otherwise it will become dull when starting.
• Hold the tool with both hands and keep it on the ground. The left hand should be on the chainsaw handle, and the right hand should be on the starting cable. Secure the tool with your right foot by stepping on the rear handle.

• Gently pull the starter rope with your right hand until you feel strong resistance. Using force, pull the starting rope several times, starting the engine briefly. In this case, to avoid abrasion, it is recommended to pull the cable upwards from the body.
• After a short start, the engine stalls. Now move the combination lever up one click. The lever should take the half-throttle position.

• Pull the starter cord again to start the chainsaw engine.
• When the engine is started by briefly pressing your finger, operate the throttle lever. The combination lever will automatically return to idle speed.
• Without touching the gas lever, move the chainsaw.
• Pull the handle towards you to release the chain brake. The position of the left hand remains unchanged, the hand is on the handle. The chain will be unlocked after the appropriate click.

You can see a detailed description on how to start a chainsaw correctly in the video. Using these detailed instructions, you can gain skills on how to start a chainsaw.

What to do if the chainsaw does not start?

But what to do if all the steps specified in the operating instructions have been followed, but the chainsaw still does not start? Regardless of the manufacturer of the chainsaw - Shtil, Husqvarna, Partner, Ural, Druzhba - a number of general activities can be identified for the tool factory.

Below are practical tips from professionals that have been tested in practice and have proven effectiveness:

1. Don't be nervous and don't try to adjust the chainsaw's carburetor.
2. Set the instrument aside and let it rest. The reason may simply be that the candles are flooded. Give them a chance to dry.
3. Take the instruction manual. Try starting the saw again. There is no need to turn on the saw brake.
4. If this does not help, try removing the cover from the chainsaw body and removing the air filter. This way you can check the cleanliness of the filter and at the same time make the starting process easier.
5. Replace the spark plugs. If it is not possible to install new spark plugs, you can use the old ones by first removing and calcining them.
6. If a strange, pungent odor appears, it means that excess fuel has entered the chainsaw engine. To correct this situation, you need to remove the spark plug and, turning the saw over with the hole down, drain the excess. Without returning the saw to its normal position, sharply pull the starter several times. This way you will ensure that combustion products leave the chamber. The spark plug must be wiped dry and calcined, and then screwed in again and started without installing the filter.
7. It is necessary to check the surface of the piston for the presence of fuel. If you unscrew the spark plug and notice through the hole that it is dry inside, you need to inject some fuel into the chamber using a syringe. The cause of problems in this case may be a blockage that interferes with the supply of fuel to the engine. If the engine can be started with a small amount of fuel, then the thrust will clear the blockage and the problem will be solved.
8. The last two actions can be performed only if the candle is dry.
9. Check the starter for serviceability. It is impossible to start a chainsaw without a starter.
10. Check the ignition unit for spark.
11. Try carefully removing the tool's muffler and starting it without it.

Each saw has its own manufacturing characteristics. You can watch the video on how to start a Husqvarna chainsaw. Follow the instructions carefully and the saw will serve you for a long time.

Is disassembly necessary?

You can adjust the carburetor of a chainsaw without any disassembly at all; in rare exceptions, you only have to remove the air filter cover. There is a considerable amount of contradiction here: on the one hand, the chainsaw is designed for unhindered access to the adjustment mechanism, on the other hand, it is recommended to access it as little as possible.

True, experienced fellers and sawers always carry a flat-head screwdriver with a long blade and periodically adjust the carburetor. This is explained simply: during the manufacture of a chainsaw, its carburetor undergoes rough adjustments designed for a certain composition of air and fuel. It is clear that the conditions at the work site are different from those on the bench.

When changing the brand of gasoline or, for example, increasing air humidity, an experienced chainsaw user will always adjust the quality of the mixture for greater performance and less wear on the piston part. But this, we repeat, requires considerable experience in working with a specific chainsaw and knowledge of the peculiarities of its behavior. In addition, the adjustment is incredibly fine - the screws are tightened only 1/10. 1/20 turn.

Another reason for adjustment is carburetor repair or replacement. In any case, adjustment of the mixture quality should be carried out only if the serviceability of the carburetor is reliably known (no debris, gaskets are not poisoned), the air filter is clean, the spark plug, clutch and ignition system are in perfect order. Otherwise, there is a high probability that the malfunction will be eliminated in a moment and the adjustment will suddenly become incorrect, and the engine will begin to wear out.

How to start a chainsaw

The question of how to start a chainsaw can be divided into two parts:

The information from the first part will be useful to those who have lost the annotation, or to those whose annotation is not very informative.

The 2nd part will tell you what needs to be done if you have done everything according to the instructions correctly, but the chainsaw still does not start. It will also be useful for those who have trouble starting their chainsaw.

1. Start the chainsaw according to the instructions

Different chainsaws may start differently. Let's look at two more popular mechanisms that are used to start a chainsaw, available today. For example, let's take the Stihl MS 180 and Echo CS-352ES chainsaws. To properly start a Stihl, Husqvarna or other brand of chainsaw, you must first read the instructions and follow its steps. If you have a chainsaw of a different brand, then just try to start it by analogy, because most likely you have the same or a similar mechanism.

Before starting the description of the starting process, I would like to see that some chainsaws have written in the annotation that before starting the chainsaw it is necessary to turn on the critical stop brake. It's safer this way. But with a fixed brake, it is more difficult to start the chainsaw, so it is better to unlock it. If you do everything wisely, then the chainsaw will not do anything for you during startup. If you are afraid that without locking the brake, the chainsaw will cause harm to you when you try to start it, then it is better not to take up this tool at all.

So, let's start with the Stihl MS 180.

The first thing you need to do before starting this chainsaw is to move the damper adjustment lever to the lower position (Fig. 1). Please note that this lever only moves all the way down on the chainsaw if the gas button is pressed. Therefore, we hold down the gas button and move the lever down. Then we close the valve in the carburetor and secure the gas in the pressed position on the chainsaw.

Rice. 1 After you have done this, then to start the chainsaw, you begin to vigorously pull the starter handle until you hear that the chainsaw tried to start and immediately stalled. Then we move the lever for adjusting the position of the damper on the chainsaw one step up (Fig. 2).

Rice. 2

• In this position, we again pull the starter handle until the chainsaw starts. With all this, if you manage to start it, due to the fact that the gas handle is fixed in the pressed position, it will immediately work at high speeds.
• Then we press and release the gas button on the chainsaw once - the throttle adjustment lever will automatically move to the working position (Fig. 3), and the speed of the chainsaw will drop.
  Now you can work. Rice. 3
• If you need to start a heated chainsaw, then you just need to put the lever in the position as in Fig. 3, and you can start it.
• To stop the chainsaw engine, raise the damper adjustment lever to the upper position (Fig. 4).

Features of maintenance and self-repair of Husqvarna brand chainsaws

Husqvarna chainsaws are indispensable assistants in the household. With the help of gasoline motorized equipment, you can perform various works related to construction, logging and simple trimming of branches. If the tool is handled correctly, it will serve for a long time, but during operation, various malfunctions occur as a result of intense loads.

When minor breakdowns are detected, they do not contact service centers and workshops; routine repairs of Husqvarna chainsaws are carried out independently, and it is necessary to investigate and analyze the probable causes of defects and ways to eliminate them.

Scope of application

The powerful, semi-professional chainsaw Husqvarna 340 can rightfully claim the status of a multi-purpose universal tool.

This model is focused on a wide range of economic work related to the procurement of fuel wood, crowning fruit and ornamental trees.

The list of tool capabilities also includes pre-assembly, transverse and longitudinal-radial cutting of construction wood, sawing of foam and gas block building materials.

The presence of special attachments allows you to use the chainsaw as a grinder, ice drill, plane, compact and efficient pump.

Why it won’t start and what to do

Among the malfunctions of the Husqvarna chainsaw are poor engine starting. The engine either cannot be started at all, or it starts poorly.

There is no clear answer to the question why the chainsaw won’t start. The main assembly unit of the tool is the engine. The following conditions affect the stability of operation:

• fuel mixing;
• air;
• presence of a spark;
• lubricant

Each factor is responsible for its own working unit:

• for the fuel mixture - carburetor;
• for air - a cleaning system, in particular an air filter;
• for the spark - the ignition mechanism and spark plug;
• lubrication - lubrication system and gasoline.

A common reason why chainsaws do not start is failure to follow the starting algorithm. The engine unit should only be started after all parts have been completely assembled:

The chain brake is always on. To avoid losing control of the instrument, you must not start in the air.

Starting the engine in a cold state is done as follows:

1. Place the tool on the ground, step on the back handle with your right foot, and place your left hand on the front handle.
2. The saw is in a stable state, the chain does not touch the ground.
3. With your right hand, take the starter handle and pull the cord, but do not twist it around your hand.
4. As soon as the first flash occurs, return the choke lever to its initial position, opening it, and repeat the start.
5. They gas it and let it go. The blocking is disabled.
6. The engine is switched to idle speed by quickly turning off the gas limiter.

Starting a warm engine is carried out in the same sequence, but without opening the damper.

If the start is made correctly, but the engine does not work, a possible reason is the lack of fuel in the tank, or the carburetor fuel chamber is not filled. Check the tank and chamber, fill them with the mixture.

If the ignition system malfunctions, inspect the spark plug and check for the presence of a spark at the electrodes. If it is wet (gasoline floods the spark plug) and a spark is not detected, the part is turned out, dried or replaced. If it is dry and there is a spark, then there is a problem in the fuel equipment - clogging, depressurization of the gas intake.

Magneto malfunctions are also confirmed by a weak spark. Despite the ignition operation, there may be no flash in the cylinder, while the spark plug removed from the cylinder is wet. The solution is to purge the cylinder with the carburetor flaps open.

The electrodes of the system are covered with soot or oily. This can be removed with a wire brush. The spark plug is washed and cleaned by allowing the gasoline to evaporate.

Violation of the gap between the side and central electrodes leads to a poor start. The normal interval is 0.6-0.7 mm. It is adjusted by hemming.

If the ceramic insulator surrounding the central spark plug or the current-carrying core of the wire is damaged, replace it.

If it starts and stalls

The Husqvarna chainsaw starts and stalls when you press the gas. This is caused by a clogged carburetor jet and a dirty fuel tank filter. The defect is eliminated as follows:

• disconnect the fuel hose from the carburetor;
• inspect the fluid leakage - the breather is clean if a full stream comes out.

The next reason why a chainsaw stalls is contamination of the muffler with exhaust resins. The issue can be resolved by cleaning.

Wear of piston rings affects the operation of the cylinder-piston group. If there is play during inspection, parts are replaced.

When starting the engine, the unit may also stall:

• as a result of water entering the mixture;
• due to poor chain lubrication;
• oil wire leakage;
• clogged channels.

Pay attention to the chain:

• if dryness increases, clean the oil supply channels, inspect the elements connecting the fittings to the tubes;
• If there is an oil leak at the connecting points or there are cracks in the tubes, they are sealed with sealant.

The engine does not develop speed:

• if the piston rings burn in the grooves;
• when the crankcase rubber seals wear out and lose elasticity;
• leaks in the connection between the cylinder and the crankcase;
• due to incorrect setting of the ignition timing;
• as a result of contamination of the cylinder fins and fan grille;
• under heavy load immediately after purchasing a new engine.

How to set up a chainsaw

In the process of repairing Husqvarna chainsaws with their own hands, they identify some malfunctions that appeared as a result of incorrect ignition adjustments and carburetor settings.

The mechanism is responsible for engine speed and is adjusted for operation taking into account the necessary conditions:

• climate:
• height above sea level;
• petrol;
• loads;
• oil used.

By default, for productive work, the factory settings of the carburetor of the Husqvarna chainsaw are set during testing.

The device has 3 customizable areas:

• “L” - low speed jet;
• “X” - high speed jet;
• “T” - idle speed adjustment screw (XX).

The standard settings are:

To set up the chainsaw, after break-in, adjust the carburetor: first work with the “L” jet, then with the XX “T” and “X” screws. When “L” and “X” are rotated clockwise, the quality of the working air-fuel mixture deteriorates; when rotated counter-clockwise, it becomes richer. Rotating the screw “T” clockwise increases the idle speed.

Modifications

Husqvarna 240 has two modifications, these are Husqvarna 240 e series and Husqvarna 240 e series TrioBrake.

In the e series configuration, the saw is additionally equipped with a Smart Start system, which is designed to make it easier to start the chainsaw, as well as hinged fuel and oil tank covers, and a chain tensioning system without the help of an additional key. Essentially, the Husqvarna 240 e-series is a luxury version of the basic chainsaw model.

Husqvarna e-series TrioBrake is also a luxury model of the 240, only additionally equipped with innovative TrioBrake technology, which protects the operator in the event of a kickback. Upon external inspection, it is very easy to identify a chainsaw equipped with this system because it has an additional lever in the area of ​​the handle under the right hand, which is responsible for activating the saw chain brake during a rebound.

The video below provides a description of how the system works and why it is needed.

How to dilute gasoline for a Husqvarna chainsaw

For productive work and increased service life at high power, maintain the proportion of oil and gasoline for the chainsaw, measuring the ratio of the ingredients of the fuel mixture with a measuring tank. When preparing even a small quantity, small inaccuracies affect the quality of the fuel.

For dilution, use high-quality gasoline with a minimum octane number - RON 90. If the parameter is less than recommended, the engine begins to knock, which leads to overheating and increased load on the bearings. When constantly operating at high speeds, choose gasoline with an increased rating.

It is recommended to use 2-stroke oil.

To properly dilute gasoline for a chainsaw, use the following mixing scheme:

• for engines with a cylinder displacement of up to 80 cm³ - 1:50 (2%), i.e. 5 liters of gasoline - 0.10 liters of oil;
• for engines with a volume above 80 cm³ - 1:33 (3%), i.e. 5 liters of gasoline - 0.15 liters of oil.

Starter repair

The starter is responsible for starting the unit. Malfunctions indicate the presence of the following malfunctions:

• the spring burst;
• the pulley is damaged;
• The starting cable is damaged.

Sequence of actions for replacing a worn starter cord:

• the starter is disassembled, the mechanism is removed, having first unscrewed the screws securing the housing to the engine crankcase;
• the cord is pulled out at a distance of 30 cm through the hole in the pulley;
• the return spring is set to the neutral position;
• the central screw is unscrewed and the pulley itself is removed;
• a new cord is inserted, tensioned, while 3 turns are wound around the mechanism and secured with a screw;
• the cord is then pulled through a groove in the starter housing and handle.

The return spring is tensioned by rotating 2 turns clockwise, taking into account that it is compressed. When replacing a broken part, the spring should pop out after pulling the inner part down.

Why is the chain not lubricated?

Oil does not flow to the saw set as a result of a malfunction in the chain lubrication system. The reasons for this are as follows:

• presence of defects in the oil pump;
• clogging of the filter, channels;
• breather defects;
• oil hose rupture;
• mismatch of the oil hole on the saw body and the bar;
• drive gear malfunction.

Dismantling and disassembling parts will allow you to correct identified defects and eliminate them by replacing them with new ones.

The oil pump is responsible for increasing or decreasing the oil supply and is located on the right side of the chainsaw. Leaking or contamination may result in insufficient lubrication. It is removed after the clutch is released.

The oil supply to the chain is adjusted by adjusting the oil pump.

Recommended saw set for Husqvarna 130

The saw set for the Husqvarna 130 is the same as for amateur chainsaws Husqvarna 135, Husqvarna 140 and another new product. Husqvarna 135 Mark II models.

That is, a laminated guide bar with a narrow shank (regular or X-Force) with a length of 35 or 40 centimeters (14″ or 16″) and chains “X-Cut S93G” and “H37″ (chain pitch: 3/8" mini .shank width: 1.3mm)

Recommended combinations guide bar saw chain ( Husqvarna ).

With a tire length of 40 cm (16″):

• guide bars with codes: “582 20 76-56” and “501 95 92-56”
• saw chains with codes: “585 40 42-56” and “576 93 65-56”

With a tire length of 35 cm (14″):

• guide bars with codes: “582 20 76-52 and “501 95 92-52”
• saw chains with codes: “585 40 42-52” and “576 93 65-52”

And quite unexpectedly, the recommended combination for a 30 centimeter (12″) guide bar was included in the list of recommendations: “501 95 92-45” “585 40 42-45”

Is it worth buying a Husqvarna 130 chainsaw in 2022 (No!!!)

How to remove and replace the drive sprocket

The chain moves along the bus by a drive sprocket, which is connected to the gearbox. It is an assembly unit that rotates due to a bearing. At the end of the tire there is a driven sprocket with the same pitch relative to the drive one. Therefore, when carrying out repair work, all factors are taken into account: the alignment of the splines, the presence of bearings, and the kinematics of the tool.

When the spline wears out, the drive sprocket is replaced, otherwise traction with the chain will not occur.

In order to change a part, you must perform the following steps:

• unscrew the nuts of the tire cover and remove the headset using working tools;
• remove the air filter;
• unscrew the saw spark plug;
• remove the clutch on the chainsaw;
• inspect the drum and check the crown;
• remove the chainsaw sprocket;
• if necessary, replace the broken part with a new one;
• Reassemble all parts in reverse order.

If the process of replacing a sprocket on a Husqvarna chainsaw is difficult, use the services of a specialist.

Purpose of the 445th model

According to the manufacturer, this Husqvarna chainsaw model is quite versatile, but it is preferable to use it for more complex tasks. It performs well in industrial wood harvesting and as a chainsaw for pruning branches.

Husqvarna 445e II, the saw is quite durable and can withstand daily work for 8 hours without any problems. At the same time, the operator will not overexert himself, since it is relatively light in weight compared to some professional Husqvarna chainsaws.

The saw can also be used in construction; it will work reliably when installing frame buildings or making log houses. Many owners use the 445 to work on sawmills or when preparing firewood for the public. Another area in which this chainsaw can work confidently is public utilities.

Husqvarna 445 is popular with electricians who clean green areas under power lines.

Break-in rules

Running in a chainsaw does not last long at XX. Therefore, after starting the engine, you need to idle for about 5 minutes, then start sawing trees with a diameter of no more than 10 cm at medium speed.

The technological process is carried out according to a cyclic scheme:

• 1.5 minutes with minimum load;
• 20 seconds on XX without it.

After operating for the first 25 hours, the unit can reach full power; all rubbing parts are worn in.

During this period, be sure to adhere to the following recommendations:

• do not overheat the power plant;
• do not work for a long time at XX;
• do not load as much as possible;
• suppress long-term slipping of the clutch.

After final running-in, the following work is carried out:

• inspection of the crank mechanism;
• cleaning carbon deposits on all parts;
• checking fasteners;
• assembly;
• preparation of a flammable mixture;
• adjusting the carburetor to maximum power under load.

The saw chain also needs running-in. Attention is paid to its lubrication and tension. The part is tensioned so that it can be rotated freely by hand. Lubrication is carried out by immersion in oil. Then the chain is run at idle for 3-5 minutes. The engine is stopped, the chain cools down and only then the tension is checked.

Chainsaw and two-stroke engine devices

By design, all models of modern chainsaws are a mechanism driven by an internal combustion engine. Usually this is a single-cylinder two-stroke version, which does not have a classic gearbox. Its function is performed by a single-stage chain transmission, which drives the saw set. The main components of the chainsaw design:

• membrane type carburetor;
• ignition;
• fuel system;
• starter;
• air purification unit;
• chain and bar;
• chain brake (contact and inertial);
• tension mechanism;
• Lubrication system.

Figure 1 - External structure of a chainsaw
Chainsaws are equipped with a centrifugal clutch, which is activated automatically depending on engine speed. With sufficient power, special elements are pressed against the inside of the drum, setting the drive sprocket in motion. The advantage of such a mechanism is that when the saw jams in a cut, the clutch begins to slip, reducing the risk of breakage of the internal mechanisms.

Important ! The internal combustion engine in chainsaws has a maximum speed of up to 13.5 thousand per minute. The quality of its work directly depends on the fuel mixture and oil.

How to start a chainsaw?

In most European models, the starting system and starter have a similar device and operating mechanism. The exception is old domestically produced chainsaws (Ural, Lesnik). There is a handle on the body through which the cable is passed. If you lift it, the cable engages with the ratchet drum, and several revolutions of the crankshaft occur. At the same time, fuel is released and ignited with the help of a spark plug, after which the chainsaw starts up. To simplify the start, the following mechanisms can be implemented in high-quality chainsaw models:

• installing a damper in the carburetor to pre-enrich the fuel mixture;
• decompression valve, which reduces the operating pressure in the engine cylinder;
• a spring that simplifies the unwinding of the crankshaft while the cable is moving;
• additional pump for pumping fuel (usually found in American manufacturers).

The starter is constantly subjected to dynamic load. Because of this, it can fail at any time right during startup. If the saw is used frequently, it is recommended to carry out preventive maintenance at least once a year. It is recommended that only two people replace the cord in the starter, as it is necessary to securely fix the spring.

The lineup

The Husqvarna company offers consumers a wide range of devices. On sale you can find professional tools designed for specialists working in the field of logging. You can also purchase devices that are used in private households. Buyers will choose equipment based on their needs.

Professional chainsaws are in demand in the woodworking and forestry industries. The Swedish brand produces gasoline-powered saws; in terms of their characteristics, all models are not inferior to the products of European and world leaders.

When choosing a suitable model, you should pay attention to the design of the Husqvarna chainsaw. It is distinguished from products from other manufacturers by its simple design

This allows you to carry out repairs on your own, without contacting a technical center.

When the saw is assembled, it consists of a body, handle and guide bar. The unit is equipped with a control button and a brake lever. There is a muffler and switches.

There are covers on the body; they perform a protective function. Thanks to them, the parts of the saw and its mechanisms are not damaged during operation. The tool is comfortable to hold in your hands, there are handles on the front and back. It is also present on the starter cord.

The tire is equipped with a saw chain; the length of this structural element differs for each model. The operator's right hand is protected by a guard. The tool has 2 reservoirs. One of them is necessary for filling fuel, and the other is for oil.

The manufacturer placed the engine under the body, where the carburetor and starter are also located. The ignition system is reliable, so the saw starts even in severe frost.

How to turn on a chainsaw?

After preparing the tool for sawing and filling the fuel tank, you can proceed directly to start-up. It should be remembered that after purchasing a chainsaw, a run-in is required - starting at idle, cutting wood (up to 10 cm in diameter) at medium speed. Foreign models reach full power after 5-7 tanks have been used up; old domestic saws are run in at partial load for 24 hours (3-4 full refills). During this period, it is strictly forbidden to heat the engine, allow prolonged idling, or apply maximum loads when sawing.

Launch stages

After all checks, you can run the tool for further work. To do this, the saw must be placed on a stable surface so that the bar does not touch the ground. Step-by-step algorithm:

1. Disengage the chain brake using the handle on the body of the chainsaw.
2. Turn on the ignition by pressing the button or switch (usually the leftmost position).
3. Move the air supply damper to the closed position. Pull out the throttle lever and lock it in an intermediate position.
4. Take the front handle with your left hand and press it lightly to the bottom. Step on the protective shield of the right handle with your foot.
5. With your other free hand, you plan to pull the starter handle towards you until the pawls in the ratchet mechanism engage the drum clutch. Make a sharp jerk.
6. After the first flash in the ignition chamber, turn the air damper to its original position. Start the saw again.

Once the engine starts, give full throttle and release the throttle lever completely. Normally, the trigger unit should automatically turn off.

Important ! The starting position of the saw depends on the specific model as well as your dominant hand. Compact versions of this tool can be launched on weight.

Features of starting with a cold and hot engine

In order for the engine to start, several processes occur simultaneously in the device. The supply of the fuel mixture to the engine piston begins, it is compressed and ignited by a spark from the spark plug. At the same time, the quality of the air mixture differs when starting with a cold and hot internal combustion engine.

If in a heated state a normal level of air is sufficient, then in a cold state there is not enough of it. In such a situation, it is necessary to pull the starter many times, which leads to wear on its cable. To regulate the supply of air mass in the carburetor there is a special damper. In cold weather, it must be opened completely, if necessary, pump fuel directly into the carburetor using a primer. This will speed up the startup of the chainsaw and reduce the risk of damage to its main components.

How to hold the instrument?

There are several methods for holding a chainsaw to start. The simplest option is to place the tool on a flat surface, grab the upper handle with your left hand, holding the guard with your foot. The second way is to hold the top handle of the saw with your hand and secure the back part between your legs. This position is only suitable for low-power and compact models of household chainsaws.

Figure 4 - How to hold a chainsaw

Checking the oil supply

To achieve the sliding of the chain along the headset, there is a special oil tank in the engine crankcase - it supplies oil to the tire. Its operation is controlled by a special pump, which starts when the engine speed increases. To check the flow and operation of the lubrication process, you need to remove the side protection of the tire and start the tool. If the oil enters the headset and decreases in the tank (check with a dipstick), then no action is required. If the amount of mixture is insufficient, it is recommended to clean or replace the filter, and then adjust the flow.

Distinctive features of winding of different brands

Some models may have a slightly different starting system. The main difference is in the location of the main elements on the body (the presence or absence of a primer, the number of bolts for tensioning the chain, etc.), as well as in the proportion of preparation of the fuel mixture. After purchasing the tool, you should carefully read the instructions, which always indicate the algorithm for the first start-up, running-in and frequency of preventive measures.

Important ! The design elements of Chinese chainsaws are especially often different. When choosing such a tool, you should check in advance for detailed instructions.

Features of launching in winter

Before starting work in winter, it is recommended to first bring the chainsaw into a warm room for 10-15 minutes. If this is not possible, start the tool at idle speed, moving the air damper to the middle position. Increase engine power only after pre-warming. Some models have the ability to switch air intake in summer and winter mode - this is the optimal solution if you often work in the forest at any time of the year.

Is it possible to start without a starter?

It is impossible to start a chainsaw without a starter. In the absence of this element, disturbances will occur in the engine cooling process, since it contains the so-called “snail” that regulates the flow of cold air from the flywheel impeller to the internal combustion engine cylinder.

Description

Chainsaw. This is a necessary tool for farming. Used for professional tree felling and for everyday garden maintenance. The saw runs on a mixture of gasoline and oil and is independent of electricity.

Contents: General characteristics of chainsaws

Chainsaws. portable machines, usually with a two-stroke engine.

The tool consists of two blocks. One contains the fuel tank and handles, the second contains the engine and saw part.

This design is due to an attempt to reduce the vibration received by the user.

The saw set consists of links and is closed in a ring. Usually it comes with a chainsaw. The chain is attached to a bar, which is a metal plate.

Its standard pitch is 0.325, 3/8 or 0.404 inches. The longer the stroke, the more aggressive the saw .

There is a pattern between the size and power of the engine and the headset used.

With an engine volume of 45 - 55 cm³, it is optimal to use a chain with a pitch of 0.325 inches. A 3/8 unit headset will require a more powerful engine.

Saw bars vary in size. The longer it is, the greater the load on the engine. Therefore, the manufacturer's recommended size should be used.

The main indicator of a chainsaw is the power of its cylinder. When choosing a tool, consider the purposes for which it will be used. A household chainsaw is sufficient for preparing firewood and cutting knots. For cutting hard and large-diameter wood, choose more powerful models.

Characteristics of the Husqvarna 135

The Husqvarna 135 chainsaw is a household type of tool. It is suitable for irregular cutting of boards and individual trees.
