Adjusting the carburetor of the chainsaw: we disassemble all the technical nuances of the worksDacha construction and correction do not do without the introduction of a chainsaw, like the upbringing of a garden. Because of a malfunction of the tool, the whole thing can arise, therefore it is unjustifiably proud to know without the help of others to decompose it, to find problems and to rid them. To be sufficient experience and skill is even possible adjustment of the carburetor chainsaw - an uneasy operation, and, more precisely, a jewelry. It seems to deceive procedures according to the regulation, and we suggest that you buy now.
The structure of the chainsaw carburetor
No repair measure can do without knowing the basics of the device mechanism. The carburettor is one of the main multifunctional parts of the engine, which serves for the preparation and operation of the engine. supply of fuel consistency, consisting of certain proportions of fuel and air. As the proportions are broken - the engine starts to"junk", and even completely ceases to do.
The correct operation of the carburettor is allowed, by examining its"stuffing":
Tube with a transverse flap for the sake of airflow adjustment.
The diffuser is a restriction for the sake of accelerating the flow of air, is located near the inlet of the fuel supply.
The atomizer from which the fuel is supplied (the fuel needle for the circuit).
The float room adjusting the height fuel to be the entrance to the channel.
Oh, it looks like this for the scheme: For the scheme, the interaction of fuel and airflow is displayed
The jet of air in the diffuser sprays the fuel, creating a mash entering the cylinder. The higher the number of incoming fuel, the higher the engine speed. Carburetors of different models work in accordance with the same scheme.
Then, like the engine started, he then stalls. Like the variation - the whole does not start. The primary cause lies in the overabundance of air and the lack of fuel.
The increase in fuel consumption, and the kind of consequence - a huge number of exhaust fumes. This is due to the recycling process - the supersaturation of the consistency with fuel.
The prerequisites for the adjustment failure can exist mechanically:
Due to strong vibration, the protective cap is damaged, as a result all three bolts lose their fixed fixation.
Due to wear on the piston part of the motor. In this case, the tuning of the carburetor of the chainsaw will help out only for the time, it is better to change the worn out detail.
Due to clogging, who appears due to poor fuel, scales or damage to the filter. The carburetor asks for a complete disassembly, washing and adjustment.
If the chainsaw suddenly ended up doing it, for the sake of finding out the circumstances, it should be bought
Step-by-step order according to the disassembly
The carburetor structure of models of different brands is virtually monotonous, therefore we take for example the Partner's chainsaw. Separate element accurately removed and stacked according to the order, so that it was then easier to assemble. Carburetor chainsaws of different manufacturers if they differ, it is not a principle
The upper end is removed by unscrewing the 3 bolts . The arrows indicate the bolts that must be unscrewed in order to remove the cover
Then remove the fuel hose, due to it - the drive rod. The upper arrow shows for the fuel hose, the bottom arrow for the drive rod
Next, remove the tip of the cable. The arrow shows the tip of the cable, who should take off
We remove the gas hose from the nozzle on the left. For the same reason, we remove the gasoline hose carefully, for who the arrow shows
The carburetor is completely disconnected, it is drunk to adjustment. Its design is quite complicated, therefore, if the carburetor is to be dismantled, The carburettor consists of a huge number of small parts that need to be disassembled in accordance with the order
Features of the option and adjustment
In order to figure out how to adjust the carburetor for the chainsaw, it is necessary to learn to distinguish three screws (some models have only one). The screws L and H are similar in appearance, in fact they are different
The individual screw has its own letter designation: p> «L"option is for the low speed;
«H» need for adjustment of the upper turns;
«T"is needed in order aDJUST Vat celibate circulation (for models with a single screw is tokmo it). <
The factory setting is good, and with the help of screws adjust the operation of the motor in special situations (the case associated with different climatic criteria). For the diagram, the outlets of the carburettor adjustment screws are seen to be closed
For the option of chainsaws use a special tool
The adjustment is done with the L and H screws. To increase the revolutions, they are rotated according to the watchman arrow. To reduce - against the watchman arrows. The sequence of using screws: L - N - T. If there are doubts about the adjustment, it is better to turn to the specialist, because the incorrect setting is therefore capable of failure.
