Observing the instructions in this manual

wear and damage to the power tool.
The power tool must be operated, 
maintained and stored with the due care 
and attention described in this owner's

The user is responsible for all damage 
caused by non-observance of the safety 
precautions, operating and maintenance 
instructions in this manual. This includes 
in particular:
– Alterations or modifications to the 
product not approved by STIHL.

Maintenance Work
All the operations described in the 
"Maintenance Chart" must be performed 
on a regular basis. If these maintenance 
operations cannot be performed by the 
owner, they should be performed by a 
servicing dealer.
STIHL recommends that you have 
servicing and repair work carried out 
exclusively by an authorized STIHL 
servicing dealer. STIHL dealers are 
regularly given the opportunity to attend 
training courses and are supplied with 
the necessary technical information.
If these maintenance operations are not 
carried out as specified, the user 
assumes responsibility for any damage 
that may occur.  Among other parts, this 
includes:
– Damage to the engine due to 
neglect or deficient maintenance 
(e.g. air and fuel filters), incorrect 
carburetor adjustment or 
inadequate cleaning of cooling air 
inlets (intake ports, cylinder fins).
– Corrosion and other consequential 
damage resulting from improper 
storage.
– Damage to the machine resulting 
from the use of poor quality 
replacement parts.
Parts Subject to Wear and Tear
Some parts of the power tool are subject 
to normal wear and tear even during 
regular operation in accordance with 
instructions and, depending on the type 
and duration of use, have to be replaced 
in good time. Among other parts, this 
includes:
– Cutting attachments (all types)
– Mounting hardware for cutting 
attachments (rider plate, nut, etc.)
