CAUTION:
Turn off the engine before cleaning the air Þ lter! Never clean out the air Þ lter with compressed air! Do not clean the
pre-Þ lter and inner Þ lter with fuel.
The service life of the engine depends on the condition and regular maintenance of the Þ lter elements. Failure to
perform maintenance and cleaning at the prescribed intervals will cause increased wear inside the engine!
If the air Þ lter 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 Þ ne 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-Þ lter
If the pre-Þ lter (1, Order No. 395 173 081) is dirty, wash it out
in lukewarm water with standard dishwashing liquid.
Rinse out pre-Þ lter thoroughly in running water.
Let the pre-Þ lter dry thoroughly.
NOTE: The pre-Þ lter must be cleaned daily, or several times
daily if working under dusty conditions. If cleaning is not
possible on-site, have spare pre-Þ lters on hand. Replace the
pre-Þ lter at least every 25 operating hours.
To insert the pre-Þ lter in the Þ lter cover (4), position it so it Þ ts
the space in the cover and then press it in (5). The pre-Þ lter
must Þ t completely and cover all parts of the Þ lter space,
without leaving any spaces unÞ ltered.
Inner Þ lters
Wash out the dirty inner Þ lter (3, Order No. 395 173 020) in
lukewarm soapy water with regular dishwashing liquid.
Let the inner Þ lter dry thoroughly.
Air Þ lter insert
The air Þ lter insert (2, Order No. 395 173 011) Þ lters the in-
take air through a very Þ ne paper Þ lter lamella system. For
the reason the cartridge must never be washed. Clean the
air Þ lter insert once a week.
To clean the air Þ lter insert, spread it out slightly and care-
fully tap it against a clean surface.
Replace the air Þ lter 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 Þ lter system, check the intake opening
to make sure no dirt particles have fallen in. If they have,
remove them.
