Do not make any changes in chain saw construction.
When not in use, chain saw should be stored clean, on flat surface, in dry place and
beyond reach of children.
When storing it is important to avoid deposition of rubber particles in basic parts
of the fuel system, such as carburettor, fuel filter, fuel line and fuel tank. Fuels with
alcohol additives (ethanol or methanol) may absorb moisture and that during storing
causes separation of fuel blend ingredients and formation of acids. Acidic petrol may
damage the engine.
5.2. Air filter.
Dirty air filter reduces efficiency of combustion engine and causes increase of fuel
consumption. Clean the air filter after each 5 hours of the saw operation.
Clean the air filter lid (4) and its surroundings, so the dirt does not get into carburettor
chamber after the lid is removed.
Unscrew knob for air filter lid (3) and remove air filter lid (4).

Use water with soap to clean the filter, wash with clean water and dry thoroughly.
Install air filter. Ensure the grooves on the air filter rim match protrusions on the
air filter lid (4).
When installing the air filter lid (4) make sure to properly place ignition plug wire
and access sleeves for carburettor adjustment screws.
Do not wash the air filter in petrol or any other flammable solvent to avoid fire
hazard or appearance of dangerous vapours.
5.3. Cylinder fining.
Dust deposition on the cylinder fining may cause motor overheating. Check regularly
and clean the cylinder fining when carrying out maintenance of the air filter.

efficient and safe operation. Operating the saw with blunt chain causes quick wear of
the chain, guide bar and driving chain wheel, and breaking the chain in the worst case.

Chain sharpening is a complex operation. Sharpening the chain by yourself requires
use of special tools and skills. It is recommended to entrust sharpening the chain to
qualified persons.
