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.
To help prolong the wear life of the 
starter rope, observe the following 
points:
N Pull the starter rope only in the 
direction specified.
N Do not pull the rope over the edge of 
the guide bushing.
N Do not pull out the rope more than 
specified.
N Do not allow the starter grip to snap 
back, guide it back into the housing 
slowly – see chapter on "Starting / 
Stopping the Engine."
Have a damaged starter rope replaced 
by your dealer before it breaks 
completely. STIHL recommends that 
you have servicing and repair work 
carried out exclusively by an authorized 
STIHL servicing dealer.
For periods of 3 months or longer
N Drain and clean the fuel tank in a 
well ventilated area.
N Dispose of fuel properly in 
accordance with local 
environmental requirements.
N Run the engine until the carburetor 
is dry – this helps prevent the 
carburetor diaphragms sticking 
together.
N Remove, clean and inspect the 
cutting attachment.
N Thoroughly clean the machine – 
pay special attention to the cylinder 
fins and air filter.
N Store the machine in a dry and 
secure location – out of the reach of 
children and other unauthorized 
persons.
