Husqvarna saw - characteristics and design of a chain saw, operating instructions, how to use

Today, it is probably difficult to meet a man who does not have in his house such an indispensable tool in everyday life as a chainsaw. Especially if he has some kind of land. In fact, a saw is an indispensable device for preparing firewood (see how to cut down a tree), working with wooden materials, etc. But of course, buying a tool is not difficult; you also need to learn how to handle it correctly. This is exactly what we will talk about in this article, namely about the operation of chainsaw models from one of the most popular companies of the present time - Husqvarna. In the article, review the operating instructions.

The ratio of gasoline and oil for a Husqvarna chainsaw

Before starting a Husqvarna gasoline saw, you need to fill it with a high-quality fuel mixture. To prepare it correctly, you need to study the instructions in the operating instructions for the garden tool you are using.

The manufacturer advises diluting fuel for Husqvarna chainsaws only with branded motor oil designed specifically for gasoline chainsaws of this brand. These oils contain all the necessary additives that clean the fuel from harmful impurities and protect the engine's rubbing parts from corrosion.

To prepare the fuel mixture, you need to use a ratio of 1:40. This means that 25 ml of motor oil must be diluted in 1 liter of fuel. This will be enough to protect the moving parts of the internal combustion engine and ensure smooth, stable operation of the engine in all weather conditions.

Operating instructions and safety precautions when handling the tool

Basic rules for operating a Husqvarna chainsaw:

• chainsaw fuel - high purity gasoline;
• the saw runs on a mixture of fuel and oil, the fuel is mixed in a ratio of 50:1, this ratio gives the best effect for engine operation. Do not change the ratio of the components of the combustible mixture!
• It is recommended to take the following types of oil: Husqvarna HP, for 2T engines, semi-synthetic;
• prepare the fuel mixture in the required proportion in a special mixing container; in no case should you dilute good gasoline with cheaper gasoline;
• It is also forbidden to dilute one type of oil with another;
• It is recommended to fill fuel away from sources of fire and gas.

Operating and safety rules for working with a Husqvarna chainsaw:

• You should always drive the chainsaw from top to bottom or sideways over the entire surface of the tree trunk; if you drive the saw only with the edge of the sprocket, you can get strong kickback from the tool and greatly increase the likelihood of injury;
• if the saw does not want to start, make sure that all components are assembled and installed correctly, and then try to determine the reason;
• Do not use the device in the rain or near fire sources;
• It is unacceptable to use a chainsaw without protective equipment (headphones, mask, glasses);
• You cannot remove the engine and disassemble it yourself while the device is under warranty.

The main malfunctions of chainsaws and how to fix them

Why doesn't the Husqvarna chainsaw work? The main causes of malfunctions and methods for eliminating them are indicated in the table.

How to start a Husqvarna chainsaw - procedure

Starting a Husqvarna chainsaw with a cold standard engine should be done in the following sequence:

1. The operator must first apply the chain brake. To do this, the built-in lever, initially located in the middle part of the body, must be pushed forward from you;
2. Next, you need to press the decompression button once, if the Husqvarna chainsaw device allows it;
3. Then you need to quickly pull the standard starter cable towards yourself several times until the saw motor starts;
4. At the end, you need to apply the gas and turn off the inertial brake by pulling its lever towards you.

This procedure must be used every time there is a cold start of the motor of the garden tool being used. If the Husqvarna chainsaw is warm, the operator simply needs to turn on the built-in ignition and quickly pull the starter cable several times. In this case, there is no need to manipulate the combination lever.

Controls

Here in Husqvarna 142 is the classic minimum. They are represented by a switch that can be set to On or Off, a choke position lever that can be in one of three positions, and a combined throttle position control lever with a stopper. Here only “suction” requires explanation. Between the fixed positions of the open and closed damper, there is a third stable position, corresponding to the half-open damper of the chainsaw carburetor. It is used when turning on a cold engine after several jerks with the starter with the throttle closed. Husqvarna 142 does not have a primer. Primary fuel pumping is carried out using the starter handle. Well, the fewer nodes, the fewer breakdowns!

Proper running-in of a Husqvarna chainsaw

The essence of running in a Husqvarna gasoline saw is to subject it to minimal loads during the first hour of working with the tool you are using.

To do this you need to act in this order:

1. The chainsaw with the standard fuel and oil tanks pre-filled must be placed on a stable, flat surface and started;
2. After this, you need to leave the saw with the built-in internal combustion engine running at idle for about 15–20 minutes. In this case, you need to press the standard gas trigger every minute;
3. Then you can move on to sawing small branches and twigs. You need to work with thin wood directly until the first tank of fuel mixture is used up;
4. After this, you need to re-thread the saw, start its engine and start working with larger branches;
5. After about 10 minutes of work, you can begin sawing large logs and trunks.

The manufacturer advises running in the Husqvarna chainsaw not only after purchasing it, but also after each long period of inactivity of the garden tool. This will protect its parts from excessive loads and will extend the life of the chainsaw engine cylinder-piston group.

About the manufacturer Husqvarna

Huksvarna is a Swiss company that is directly involved in the manufacture and production of tools and equipment designed for work both in the garden and in the construction industry.
The products manufactured by this manufacturer include: lawn mowers, saws, specialized tools for cutting stone materials and others. It is precisely due to the fact that the company takes the production process itself quite seriously , uses exclusively high-quality materials and modern innovations, that consumers fully trust it. In this article you can get acquainted with the best models of this world-famous manufacturer and find out why it is the leader in the electrical engineering market. So let's get started.

Adjusting the Husqvarna chainsaw carburetor

It is necessary to adjust the standard carburetor of Husqvarna gasoline saws in case of unstable engine operation at low and high speeds, a sharp increase in the volume of fuel consumed, as well as when the engine randomly turns off immediately after starting it. Correctly adjusting the carburetor on a Husqvarna chainsaw is only possible if the factory engine of the tool used is in fully working order.

Setting up the Husqvarna chainsaw carburetor should be done in the following sequence;

1. First, on a saw with the engine not running, you need to move the bolts H and L clockwise until they stop. Immediately after this, both screws need to be turned about a quarter of a turn in the opposite direction;
2. Then you need to start the internal combustion engine of the Husqvarna saw and let it idle for 5 minutes;
3. After this, you need to set up stable operation of the built-in motor at idle speed. To do this, the operator must alternately turn the metal screw L in different directions immediately until the standard engine begins to operate as stably as possible. Immediately after this, the built-in screw L will need to be turned about a quarter turn directly counterclockwise;
4. If after this the used chain on the standard Husqvarna chainsaw bar continues to rotate, it means that you need to turn the T screw clockwise or counterclockwise. As a result, the chain should stop.

After completing the steps, you need to check the operation of the household garden tool. A chainsaw with a properly adjusted carburetor will quickly gain speed immediately when you press the standard gas trigger and just as quickly lose it when you release the trigger. If this does not happen, then the carburetor adjustment will need to be repeated.

What is a carburetor?

A carburetor is a device that has the following functions: mixing gasoline and air, creating a combustible mixture to power the engine and regulating its flow. Husqvarna carburetor parts are made by casting from various alloys with further mechanical finishing. This ensures the high quality of Husqvarna carburetors, which you can verify by purchasing this spare part at the 220 Volt store.

This is an integral element of many tools among garden petroleum equipment, for example, chainsaws, brush cutters, and lawn mowers. In a number of situations, for example, with poor fuel filtration, the carburetor may fail. Fortunately, this will not be a reason to spend money on a new tool, because you can buy a carburetor separately (both regular and assembled).

A carburetor is a device that is designed to prepare a combustible mixture of liquid fuel and air, which ensures the operation of carburetor internal combustion engines.

The carburetor is one of the main parts of any fuel-powered equipment. To ensure normal and stable operation of the equipment, the carburetor must be periodically checked and, if necessary, adjusted.

Chainsaw carburetors have three adjustment screws. The “L” screw is designed to regulate low speeds, the “H” screw is responsible for regulating high speeds, and the “T” screw is for idling the chainsaw. So, with screws “H” and “L” the ratio of the mixture of air and gasoline is adjusted; when the screws are unscrewed, the speed increases, as the mixture becomes richer, and when tightened, the speed drops.

A versatile, multi-purpose saw for part-time use. Narrow and sleek body, excellent power-to-weight ratio, and some of the best vibration performance of any saw available. The economy pump stops supplying lubrication to the chain when the saw is idling. Easy Start system - a new spring-loaded starter mechanism and fuel pump that reduce the number of jerks required to start.

Air injection Air injection Centrifugal air cleaning system for long filter cleaning intervals, trouble-free operation and reduced wear. Easier to start Combination regulator/stop makes starting the saw easier. Decompression valve Easy to operate The narrow body, high center of gravity and flat bottom make our saws extremely easy to use.

Easy to clean The bayonet-mounted air filter makes it easy to remove the filter for cleaning.

Safety in use The double-action chain brake, right hand guard and chain stop increase the safety of working with the saw.

Replacing a sprocket on a Husqvarna chainsaw

As a result of intensive use of a Husqvarna chainsaw, the drive sprocket is one of the first to wear out. Because of this, the guide bar begins to heat up, and the chain on it either rotates with great effort or stops rotating completely.

To remove the sprocket from the Husqvarna chainsaw, you need to act in the following sequence;

1. First you need to remove the right side cover of the tool body;
2. Then you will need to loosen the chain and remove the tire;
3. Next, you need to carefully unscrew the spark plug - this way, the operator will have free access to the piston of the internal combustion engine of the chainsaw being used;
4. After this, you need to start manually rotating the sprocket. At the same time, the piston will rise up. Once it reaches the highest point, it can be secured using a rubber bushing;
5. The operator will then be able to unscrew the sprocket itself.

In the end, all that remains is to remove the part and install a new drive sprocket in its place. Further assembly of the Husqvarna chainsaw is performed in the reverse order.

Why the Husqvarna chainsaw does not start - reasons and repairs

Malfunctions associated with the failure to start Husqvarna chainsaws most often indicate a severely clogged fuel filter, as a result of which fuel does not enter the tool’s engine cylinder. To solve the problem, you need to carefully remove the filter element and clean it. If a hole has formed in the filter, then the part will need to be replaced.

If the Husqvarna chainsaw does not start, this indicates a violation of the optimal clearance between the factory flywheel and the built-in ignition coil of the tool. In normal operation, the distance between these parts should be 0.2 mm. If the gap is larger or smaller, the spark plug will not be able to produce the spark required to ignite the fuel in the cylinder, as a result of which the saw will not start.

To set the gap, the operator will need a template of the appropriate thickness.

Next you need to proceed in this order:

1. First you need to remove the side cover that protects the ignition system of the Husqvarna chainsaw;
2. There are 2 bolts located next to the flywheel. By turning them counterclockwise, the operator will be able to move the flywheel away from the reel;
3. Next, you will need to attach a template to the existing coil and start turning the screws clockwise;
4. Once the flywheel is very close to the template, the screws can be loosened and the side cover can be replaced.

After completing the steps, you need to try to start the chainsaw. If the gap setting was done correctly, the tool motor will start after 2-3 manipulations with the starter.

Husqvarna chainsaw stalls when pressing gas

The main reason for this malfunction is the wear of the air and fuel filters. In the first case, air does not enter the carburetor, which is why the engine cannot create enough thrust to operate at low and maximum speeds. If the fuel filter is clogged, the cylinder does not receive enough fuel necessary for its stable operation.

Cleaning the filters will help solve the problem. To do this, you need to remove the elements, clean them from dust and put them in a container with clean gasoline for a day. After this, the filter must be thoroughly dried and reinstalled. If a large number of holes or abrasions have formed on the surface of the parts, then it is best to replace them.

Why is the chain on the Husqvarna chainsaw not lubricated?

The essence of this breakdown, as a rule, lies in the wear of the oil pump, which is responsible for pumping lubricant to the headset of the Husqvarna chainsaw. As a result, the chain of the garden tool does not rotate, or it continues to rotate, but with quite a lot of force.

In this case, the operator can repair the mechanism independently. To do this, you need to remove and disassemble the pump. After this, you will need to wash its parts and replace the rubber bushings - most often, due to their deformation, all the chain oil flows out, and only a small amount of lubricant gets into the pump itself.

If the lubricant does not reach the chain even after replacing the bushings, then it is best to completely replace the pump. To do this, it is better to choose branded Husqvarna oil pumps, since any Chinese copy will last 2-3 times less than the original.

Malfunction of the chain lubrication system in the chainsaw

What types of breakdowns occur in the chain lubrication system:

• No or low oil supply
• Oil leakage

In the first case, we first inspect the channels through which oil is supplied to the tire and clean them. Their clogging is a fairly common occurrence.

If there is significant oil leakage (small oil leakage is normal for all gasoline saws), you should check the tightness of the tubes and fittings of the oil pump. Tubes may fall off and even crack. Violation of the tightness of the tubes is eliminated by replacing them or sealing them with sealing material.

As for oil pumps, they may have different designs for different models of chainsaws, and the drive is also carried out differently (as a rule, the drive is carried out by a drive sprocket or a special gear on the crankshaft). If there is a problem with the oil pump, then most often you will not have to completely replace this entire unit; it will be enough to replace its moving part (plunger), which most often fails due to the ingress of large amounts of dirt and sawdust.

The most serious damage is a crack in the oil pump housing. In this case, you will have to completely replace it.
