Damage
Observing the instructions in this manual helps

age to the power tool.

and stored with the due care and attention

The user is responsible for all damage caused by
non-observance of the safety precautions, oper‐
ating and maintenance instructions in this man‐
ual. This includes in particular:

15.1 Maintenance Work
All the operations described in the "Maintenance
Chart" must be performed on a regular basis. If
these maintenance operations cannot be per‐
formed 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 author‐
ized 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 defi‐
cient maintenance (e.g. air and fuel filters),
incorrect carburetor adjustment or inadequate
cleaning of cooling air inlets (intake ports, cyl‐
inder fins).
–
Corrosion and other consequential damage
resulting from improper storage.
