Engine Running Behavior

If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor is properly
adjusted, the cause may be the muffler.
Have the muffler checked for
contamination (carbonization) by your
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.

Storing the Machine

If the machine is to remain out of use for
approx. 3 months or more
Drain and clean the fuel tank in a
N
well ventilated place
Ensure that the fuel is disposed of
N
correctly and without harming the
environment
Run the engine until the carburetor
N
is dry, this helps to prevent the
carburetor diaphragms sticking
together
Thoroughly clean the machine - pay
N
special attention to the cylinder fins
and air filter
Remove, clean and inspect the
N
working tool
Store machine in a safe and dry
N
place. Protect against unauthorized
