DIY Carburetor Settings

The principle of operation of the carburetor of the chainsaw also includes the supply of the air mixture to the device. As you know, not pure fuel (oil with gasoline) enters the combustion chamber, but the fuel mixture is oil with gasoline from the tank and air, which previously passes through the filter element.

It is interesting!The filter that is installed on the carburetor must be regularly cleaned, otherwise its clogging helps to reduce the flow of air into the system, which often causes improper operation of the unit. Many inexperienced sawmen are immediately accepted for setting up the carburetor, however, it is enough to clean the filter and blow it up with a compressor to eliminate the causes of uneven or unstable operation of the tool. So, the air passes through the filter, and enters the device through the membrane under number 7.

Air damper 7 during cold starting is almost completely closed, as shown in the diagram. Through it there is a slight flow of air into the system. Air enters the diffuser 16. Number 12 indicate channels or nozzle nozzles and medium speeds. These channels are interdependent, that is, the average speed channel is transitional from the idle. These channels are constantly open, so the fuel in the corresponding dosage enters the diffuser, where it mixes with air, heading for the cylinder.

Under number 15, the maximum speed channel is indicated, which consists of a valve with a rubber base. Through this valve, fuel is supplying in one direction. Into the camera of the diffuser. Next, the throttle 8 enters the system, the movement of which depends on the force of pressing the gas gas on the gas. When starting the valve 8 vertical position, so the chainsaw works only on the fuel mixture coming from the xx channel. The amount of air is small, since the damper 7 is also open by several millimeters. When pressing the trigger of the instrument, the damper is deviated by 10-15 degrees, as a result of which the fuel mixture from the medium-speed channel 12 on the diagram above is supplied.

When the saw begins to saw wood, then the number of revolutions increases to maximum, so the damper moves to an angle of up to 90 degrees from the original position. An increase in the amount of fuel occurs, which helps to accelerate the burning of the fuel mixture.

To fill the chamber with a 14.Fuel mixture of gasoline with butter, which enters the channel closed with a needle, you need to create a vacuum, due to which the membrane 13 will be pulled inside, thereby acting on the stem. The vacuum in chamber 14 is created while pulling the starter handle when the crankshaft moves the tool. The piston moves up and down when “shhrings” or “poked” the starter handle, which provokes the creation of pressure inside the camera 14. As a result, the camera is filled with fuel, which enters the corresponding channels to the diffuser, mixing with air, and heading for the cylinder.

After the unit engine is launched, the piston will begin to move under the influence of the burning mixture, so the vacuum in the chamber is formed constantly, which actually provokes the bending of the plate 13, which affects the needle valve through which fuel enters the main chamber of the carburetor of the tanker.

Actually, this is the principle of operation of the carburetor of the chainsaw of the membrane type, the functioning of which does not depend on the angle of its location. Knowing the design and principle of operation of the unit, you can begin to set it up, cleaning and adjusting it.

The main malfunctions of the Stihl brand and ways to eliminate them

  • STIHL chainsaw refuses to start. Reason: Fuel, air filter is clogged, not enough fuel mixture. Elimination: cleanse the filters, add the fuel mixture, monitor the quality of the fuel, this contributes to better operation of the device.
  • The chainsaw does not work at full power, makes extraneous sounds, for example, knocking or rattling. Reason: Carburetor adjustment is required. Elimination: conduct an adjustment of the carburetor in the service if you drank under warranty.
  • The chainsaw stopped gaining power. Reason: problems with the piston group, you need to adjust the carburetor. Elimination: Check the condition of the engine, carburetor and fuel filter, as well as ignition systems.

When you need to set the carburetor?

Initially, from the moment the tool is sold, all carburetors are adjusted and set up at the manufacturer. However, in the process of work, the settings are gradually being knocked down, and the functioning mode changes in accordance with the operating conditions. Signs of problems in the operation of the carburetor can be:

  • Too high gasoline consumption, thick smoke comes from the exhaust pipe;
  • The engine power is clearly not enough to perform ordinary tasks;
  • Engine revolutions “swim”;
  • After starting, the motor stalls either immediately or after a few seconds;
  • The engine is generally impossible to start;
  • “Shoots” chainsaws, harsh claps occur in the engine engine.

Note! The reason for the poor operation of the engine may be the wear of the piston group, then the adjustment of the carburetor of the chainsaw does not give a complete resolution of the problem. Also, no setting will give the expected effect if in parallel the node is not cleaned of small particles of garbage. The most problematic elements are nozzles and filters, both gasoline and air.

It must be taken into account that during the run.In the new engine, the carburetor is tuned for reduced fuel supply, in order to limit the engine power. After the end of the runaway, the fuel supply increases to the nominal value. These settings are made using adjusting screws on the carburetor housing (usually two or three).

Starter device, principle of operation

Almost all manufacturers when assembling chainsaws use a starter of the standard design, which works according to a simple principle.

  • In a small groove of the tool case there is a pen where a special cord is located.
  • When the operator raises the handle and the cord. This affects the drum (the hook occurs) located in the ratchet system (a simple mechanism that is the same in almost all models of chainsaws).
  • After engaging the drum, the latter begins to interact with the spits who are attached to the shaft.
  • At the same time, the crankshaft rotation occurs, which causes the compression of the fuel mixing oil, which takes place in the gap between the piston mechanism and the cylinder (its head).

When the operator lowers the handle, the spitz and the ratchet stop the contact and the shaft stops.

Когда мощность топливной воспламеняемой смеси улучшается (используется премиальная или предварительно проводится настройка топливной системы), это положительно сказывается на мощности бензопилы. Then you can start the tool with several jerks of the lace of the starter mechanism. To achieve maximum drum acceleration (return mechanism), manufacturers use a specialized return spring made of high.Quality metal with good elasticity.

To facilitate the launch of the unit, the leaders of household appliances use:

  • A separate damper, due to which the fuel mixture is enriched;
  • Integration of the decompression valve (automatic system), which provides a decrease in the pressure indicator in the tool cylinder;
  • Installation of the primer, which pumps fuel until the engine starts;
  • Preliminary enrichment of the fuel mixture using a separate damper.

All these technologies simplify the easy launch of the starter system, and also extend the operation of this part, even if the chainsaw is actively used by the operator at low temperatures.

Replacement of the starter

The procedure for replacing the starter of the chainsaw:

  • Remove the knot from the tool.
  • Unscrew the fasteners and dismantle the side cover.
  • Unscrew the mounting screw with which the starter is attached.
  • Remove the clamp and the spring mechanism of the launch system.
  • Shout with a cord.
  • Replace all worn out and damaged elements.
  • Perform the pulley winding.
  • Install a new starter.
  • Install the pulley with a cord, clamp and spring in place.
  • Screw the side cover and install the node on the chainsaw housing.

Before installing a new starter, it is recommended to inspect it for a marriage, check the build quality and the presence of a guide sleeve.

DIY chainsaw repair principles

Chainsaw. An indispensable tool in the life of a home master. With it, you can saw off the old tree, build a bathhouse or just a gazebo for relaxation. Sometimes this tool also becomes unusable. To solve the problem, it is not necessary to contact expensive specialized services, you can repair a chainsaw with your own hands.

Independent repair

For repair at home, it is necessary to have spare parts, tools and appropriate skills. For example, a home.Made remote control can be useful for disassembling a chainsaw, which will have to be made for a very long time.

In some modern devices of semi.Professional and domestic type, appropriate tools are not attached to adjusting the carburetor and analyzing the drive asterisk.

General principles of disassembly

Basically, all chainsaws have the same components that are dismantled according to a certain scheme. If the assembly of the saw is Chinese, then there is nothing to worry about: most often they are done in the likeness of European models. How to disassemble a chainsaw:

  • The clutch cover is removed.
  • The starter cover is removed. To do this, you need to unscrew the screws and remove the transverse handle.
  • To remove the handle, you need to remove the lid that closes the air filter.
  • The gasoline hose is removed from the fitting cover.
  • The saw case is dismantled. You need to unscrew the screws and remove the oil tank cover.
  • Before you remove the ignition module, you need to analyze the clutch drum: you need to scroll the crankshaft clockwise until the piston blocks the exhaust opening of the gas.
  • Then you need to unscrew the clutch on the chainsaw and remove the coupling: you need to slightly hit it with a hammer.
  • Screws are removed, a gas tank with an oil hose is dismantled.

Possible problems

The problem arising during the repair is the lack of the necessary information on the repair. This is due to the fact that many foreign manufacturers believe that the saw should be disposed of after a certain period and production. Therefore, many masters have certain doubts, especially when repairing budget models.

How to assemble a tag on a trimmer

Repair of a gasoline trimmer for grass may be required at the most inopportune moment. In this case, there are two ways to solve the problem: replace a broken part or replace the entire assembly. The last option will cost more. To repair the device with your own hands, in most cases you will need only a screwdriver with an appropriate tip. Repair work does not take much time and do not require special knowledge. To achieve the desired positive result, it is enough to know the device, the principle of operation, the nuances of assembly and disassembling the starter on the trimmer.

The device and principle of the starter on the trimmer

Gas engine. This is, in principle, the main part of the brush. Its power is in the range of 0.5-2.5 liters.With. Movement from it is transmitted to the shaft located inside the hollow rod, and then through a gearbox consisting of gears, already fishing line or knife (working body).

Bigorezes also have the following elements:

  • Corrugated board;
  • Lever arm;
  • A belt designed for the convenience of using the device;
  • Starter used to launch an internal combustion gasoline engine.

make, tank, chainsaw, starting

All details of the brush are presented in the photo below.

The trimmer starter is an integral part that launches the engine. This is shown separately in two photos below.

The starting mechanisms of different models of gasoline bite to work on the same principle: when starting the internal combustion engine, the protrusions indicated by the number 1 in the photo above are included in the hook with dogs 3. When the engine is launched, they return to the previous position under the influence of centrifugal. A similar role is played by wires 2.

The process of returning to the initial position of the elements of the mechanism is due to the presence of a spring wound around the axis. It turns around when the rope is pulled. After releasing the cord, it is pulled and wound, collecting the spring. When the internal combustion engine starts, the trigger rotates its shaft until it starts (does not start).

Today, gasoline scooters are equipped with two types of starter mechanisms:

The first option is much more common.

A trimmer starter can work for a long time without breakdowns. It is impossible to unequivocally indicate the period of continuous time. Everything is determined by the initial quality of the device and compliance with the rules of handling it.

The main malfunctions of the trimmer for the grass of the starter

It is easy to determine the reason for the refusal of the circuit breaker. There are several main options:

It may happen that the starter mechanism is accidentally broken. The consequences will be deplorable if you wrap the rope on the flywheel of the current internal combustion engine: then the spring will burst, the pulley will break. But such cases when a complete replacement of the starter is required are extremely rare. In most cases, it is enough to put a new spring or replace the cord to fix the mechanism.

Removing and disassembling the starter, replacing broken parts

To repair the starter of the trimmer for the grass, it first needs to be disassembled, and then collect it. This process is not particularly complicated. You will need to work the shape of the screwdriver.

Everything should be done carefully, observing precautions, especially so that the spring does not injure the owner in case of accidental departure.

make, tank, chainsaw, starting

Starter installation analysis

Disassemble the trigger to install new parts instead of broken in the next sequence:

  • Unscrew the screw that attaches the pulley with the starter lid using a screwdriver;
  • Remove the spring and antennae;
  • Carefully remove the pulley (you need to turn your head or work, after putting on your glasses and gloves);
  • Determine why the trigger has broken;
  • If the spring fell apart almost completely, it is replaced;
  • Когда пружина выходит из крючка, она устанавливается на прежнее место, предварительно сгибая антенну (на фото показан процесс установки);
  • After the spring plate is installed inside the groove, carefully tighten it.

To change the spring, the work should be done carefully and accurately: it can accidentally explode under the influence of the force caused. Even if you carefully remove the video, the spring tape very quickly breaks away from the coil and can injure the hand with sharp edges.

Immediately put back a spring plate does not always work. This often slips, so attempts should be repeated to achieve the desired result.

Starter assembly

The assembly of the starting installation is carried out in several stages:

  • The coil turns over, installing it so that the bend of the spring accurately enters the groove of the case, as in the photo below;
  • Fold two washers between which the spring is located;
  • Put a cup with a mustache in place;
  • Tighten the screw (photo below).

When making the above manipulations, it is necessary to put two goals. If this is not done, the spring will ultimately damage the plastic cup, and when it is removed, jamming will begin. This makes you feel that spring has come. To eliminate this drawback, it is necessary to install this part of a larger length or an additional goal.

When such details are not enough, you can just unscrew the screw a little, and the starter assembly will start working without fixing. But this option is temporary. It is better to repair it as soon as possible.

Spring tension

After installing the spring, tighten it. To do this, follow the following actions:

  • Remove the handle from the starter cord;
  • Then the rope is inserted into the groove of the coil;
  • The spring is delayed by the rotation of the turn in the opposite direction clockwise (winding);
  • Make the required number of revolutions specified in the instructions for the operation of the used trimmer model for the grass, and the corresponding length of the cord used;
  • At the very end, the rope is lowered into the hole provided for this, located in the starter cover;
  • Place the handle in place by fixing it with a node.

Malfunctions of the Chinese chainsaw: review of popular and ways to solve them

Buy cheap chainsaw of China’s production is not particularly difficult: in the markets, construction hypermarkets and online stores, a huge number of gas-tools from the Middle Kingdom are presented. However, at a low price, poor quality is almost always hidden.

The most popular malfunctions of Chinese chainsaws should be attributed:

  • Poor lubrication system. Clogged oil channels are cleaned, and if the oil pump is out of order, then replacement is necessary.
  • The starter cable is torn.
  • Basement of the plastic axis of the starter. An ordinary metal bolt is suitable for replacing it.

In the case of the slightest suspicion of incorrect operation of the chainsaw, it is worth immediately making a complete diagnosis of the tool. Only with proper operation and timely maintenance can one count on a long time for using the chainsaw.
