Malfunctions of the Husqvarna 240 chainsaw
And this world famous chainsaw model is not immune to breakage. Most often they can be associated with:
- incendiary system;
- silencer;
- spontaneous leakage of fuel;

We consider separately some of them. their causes and solutions.
Why is gas coming out of the Husqvarna 240 chainsaw?
This unpleasant phenomenon may be preceded by:
- depressurization of the fuel tank;
- breakthrough of fuel supply pipes;
- primer malfunctions;
- Leaky gas tank cap.
Similar is also observed if the gas tank is poured under the very top and sawed in an upright position.
Such defects are fixed as follows:
- spare parts are replaced. a gas tank or a gas hose;
- under the cap of the tank lies a gasket that will not let the liquid out.
Husqvarna 240 chainsaw stalls under load: what to do?
A tool that works only at low speeds, and with their increase, begins to slip and gradually turns off, speaks of:
- problems in the carburetor part. improper adjustment, its clogging, depressurization;
- air loss due to oil seals or carburetor gasket itself.
In both cases, it is necessary to re-install the carburetor, which we will talk about later. If this also does not help, it is removed, cleaned and fitted with new oil seals and gaskets.
Do-it-yourself carburetor adjustment for the Husqvarna 240 chainsaw
Correct installation of the carburetor scheme is the key to the stable operation of not only the engine, but also all other gasoline equipment systems. It is based on the 3-jet principle:
- jet "T" is responsible for idling;
- "N". for high speed;
- “L”. low speed screw.
Their reconfiguration is required in such cases:
- if the gas cutter does not start;
- the saw does not function at idle and does not keep high speeds;
- increased gasoline consumption;
- caustic exhaust gases appeared (fuel partially burns out).
In any case, during carburetor tuning, the chainsaw cannot be deviated from the operating instructions, which detail the process diagram.
Timely diagnose your tool for breakdowns and use only high-quality components and technical fluids.
