8.3 Maintenance of the air filter
Dirty air filters reduce the power output of the engine. They increase fuel consumption and therefore
the pollutants in the exhaust. In addition they also make the starting process more difficult.
If the chainsaw is in all-day use then both air filters (the pre-filter (if equipped) and the main air filter)
must be cleaned on a daily basis. It may also be necessary to clean them in between if the level of
dust is very high.
Carry out the following maintenance jobs regularly.
• Take off the cowl of the chainsaw (Chapter 3.4)
• Pull out the choke lever (7).
• Unhook the spring clamp.
• Remove the air filter.
• In case of severe contamination, open
the air filter with a small screwdriver
applied to the tabs.
• To clean, simply tap out the filter or carefully clean it with compressed air. When using
compressed air, always wear suitable eye protection (protective goggles) and do not apply the
compressed air too close to the air filter.
• In case of severe contamination, the air filter can be cleaned with non-flammable cleaning fluid
(warm soapy solution).
The air filter must be absolutely dry before it is reinstalled.
The corresponding parts should be replaced immediately if the filter material is damaged. No
warranty claims can be accepted for engine damage arising as a result of inadequate care.
• Prior to installation, clean dirt and dust particles off the choke valve with a paintbrush.
• Reassemble the air filter (if opened).
• Position the air filter again and close with the spring clamp.
