8.3 Maintenance of the air filter

Dirty air filters and pre-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.

Removing the pre-filter

• Position a screwdriver on the protruding tab

(e) of the pre-filter and pull out the pre-filter.

• When inserting the pre-filter again

afterwards (after cleaning), make sure that

the thickened part (lug) on the pre-filter

engages in the housing cover (23) on the

side.

Removal of the main air filter

• Take off the cowl of the chainsaw (Chapter 3.4)

• Pull out the choke lever (7).

• Take off the main air filter (32) by undoing the

two retaining screws (a).

• To open the main air filter, slide the clamping

profile (b) to the side.

• When the main air filter is subsequently refitted

(after cleaning), make sure that clean contact is

made at the carburettor

• 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.

• If they are more heavily contaminated, both filters can be cleaned with non-flammable cleaning

fluid (warm soapy water).

Both filters must be absolutely dry before they are refitted to the device.

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.
