larger side of the enclosed Combi tool.

Clean or replace the spark plug with a new one of

plug with a wire brush and adjust the electrode
distance to approx. 0.65 mm (if necessary).
An incorrectly adjusted carburetor, an incorrect
oil/fuel mixture or dirty air filter may cause contami-

Maintaining the Saw Chain
ATTENTION! To ensure proper and safe operation of the gasoline
chain saw make sure the cutters of the saw chain are always sharp.
The cutters need to be sharpened when:
- Sawdust becomes powder-like,
- You need extra force to saw in,
- The cut way does not go straight,
- Vibration increases,
- Fuel consumption increases, too.
All chain saw service should be performed by competent chain saw
service personnel.
There are two circumstances that can cause kickback when using a
chain saw. The first occurs when the moving chain at the tip or the
nose of the guide bar strikes an object. The second situation is when
the wood closes in, pinching the saw chain in the middle of the cut.
Both of these situations cause the chain saw's guide bar to launch (or
"kick") up and back, which may cause the user to lose control of the
saw possibly result in injury to themselves or others.
The following the factors (alone or in combination) can increase the risk
of chain saw kickback:
- improper saw maintenance,
- dull chain,
