Operating and maintenance notes
ENGLISH
30
Maintenance and repairs of state-of-the-art power tools and their safety-relevant assemblies require
qualified specialist training and a workshop equipped with special tools and test devices. Therefore, we
recommend that all work not described in these operating instructions and all work you are not comfortable
with be performed by a specialist workshop authorised by us. The specialist has the required training,
experience and equipment and can make the most cost-efficient solution available to you. He will advise
and support you.
Observe the safety provisions for any maintenance work!
After a run-in time of approx. 5 operating hours, all screws and nuts that can be
reached (except for carburettor adjustment screws) must be checked for tight fit and
tightened again if required.
It is best to keep the power tool in a dry and safe site with a full fuel tank.
There must not be any open sources of fire or the like nearby.
Before extended storage (>4 weeks), observe the notes in chap. 8.10 on page 39.
The power tool must be cleaned thoroughly after every work deployment and checked for damage; in
particular the cooling air openings in the starter housing must be clean and free.
Inside the protective cowl, material deposits will form over time (in particular when wet cutting), which may
impair free rotation of the cutting disc.
Only use the environmentally compatible cleaning agents offered by specialist vendors for cleaning. Never
use fuel to clean!
