Cleaning the protection hood
Over time, the inside of the protective hood can become caked
with material residue (especially from wet cutting), which if
allowed to accumulate can hinder the free rotation of the cut-
ting disc. For this reason the hood must be cleaned out from
time to time.
Take off the cutting wheel with spring washer and remove the
accumulated material from inside the hood with a strip of wood
or similar implement.
Clean the shaft and all removed parts.
NOTE: To install the cutting wheel see ”Mounting the cutting
wheel”.

Cleaning / changing the air Þ lterCAUTION:
Turn off the engine before cleaning the air Þ lter! Never clean
out the air Þ lter with compressed air! Do not use fuel to
clean the air Þ lter insert (3) and inner Þ lter (6).
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.
Loosen both bolts (1) and remove the Þ lter cover (2).
Take the air Þ lter cover (3) out of the cover (5).
Loosen the six bolts (4) on the cover and remove the cover.
Remove the inner Þ lter (6).
When reassembling, make sure that the two lugs (7) of the
Þ lter cover engage in the cover (5).
Inner Þ lter
Wash out the dirty inner Þ lter (6, Order No. 315 173 020) in
lukewarm soapy water with regular dishwashing liquid.
Let the inner Þ lter dry thoroughly.
Air Þ lter insert (paper cartridge)
The air Þ lter insert (3, Order No. 315 173 010) Þ lters the intake
air through a very Þ ne paper Þ lter lamella system. For this
reason the cartridge must never be washed or cleaned with
compressed air. Check the air Þ lter insert once per month and
clean if necessary.
To clean the air Þ lter insert, spread it out slightly and carefully
tap it against a clean surface.
Replace the air Þ lter insert every 500 operating hours. Re-
place 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.
