CAUTION:
Turn off the engine before cleaning the air filter! Never clean out the air filter with compressed air! Do not clean the
pre-filter and inner filter with fuel.
The service life of the engine depends on the condition and regular maintenance of the filter elements. Failure to
perform maintenance and cleaning at the prescribed intervals will cause increased wear inside the engine!
If the air filter becomes damaged, replace immediately! Pieces of cloth or large dirt particles can destroy the engine!
Do not work in dusty conditions when it can be avoided! The fine dust generated when dry-cutting concrete and stone
is hazardous to the health of the operator and also shortens the service life of the engine. Whenever possible, wet-cut
with water when working in concrete and stone, to bind the dust.
Pre-filter
If the pre-filter (1, Order No. 395 173 081) is dirty, wash it out
in lukewarm water with standard dishwashing liquid.
Rinse out pre-filter thoroughly in running water.
Let the pre-filter dry thoroughly.
NOTE: The pre-filter must be cleaned daily, or several times
daily if working under dusty conditions. If cleaning is not
possible on-site, have spare pre-filters on hand. Replace the
pre-filter at least every 25 operating hours.
To insert the pre-filter in the filter cover (4), position it so it fits
the space in the cover and then press it in (5). The pre-filter
must fit completely and cover all parts of the filter space,
without leaving any spaces unfiltered.
Inner filters
Wash out the dirty inner filter (3, Order No. 395 173 020) in
lukewarm soapy water with regular dishwashing liquid.
Let the inner filter dry thoroughly.
Air filter insert
The air filter insert (2, Order No. 395 173 011) filters the in-
take air through a very fine paper filter lamella system. For
the reason the cartridge must never be washed. Clean the
air filter insert once a week.
To clean the air filter insert, spread it out slightly and care-
fully tap it against a clean surface.
Replace the air filter insert every 100 operating hours.
Replace it immediately if there is a drop in power, drop in
speed, or smoke in the exhaust.
Before installing the filter system, check the intake opening
to make sure no dirt particles have fallen in. If they have,
remove them.
