Cleaning: Rinse off coarse dirt in running water.
Knead a capful MAKITA filter cleaner (Order No. 980 008 627
into the foam material of the pre-filter (1, Order No. 395 173
090) until it suds up well.
Rinse out pre-filter thoroughly in running water.
Let the pre-filter
dry thoroughly
.
In order to ensure full filtration effectiveness, air-filter
oil
must
be used with the pre-filter. Wet the pre-filter
with a capful (about 20 ccm) of MAKITA air-filter oil
(Order No. 980 008 628, biodegradable).
Knead the pre-filter to evenly distribute the oil. Then
squeeze out any excess oil.
NOTE:
If using other air-filter oils, follow the manufacturer’s
instructions.
If cleaning is not possible on-site, have spare pre-filters on
hand (Order No. 395 173 090).
To insert the pre-filter in the filter cover, 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
(all models)
Wash out the dirty inner filter (
3
,
Order No. 395 173 020)
in lukewarm soapy water with regular dishwashing liquid or
MAKITA filter cleaner (Order No. 980 008 627).
Let the inner filter
dry thoroughly
.
Air filter insert
(paper cartridge, all models)
The air filter insert (
2
,
Order No. 395 173 010
) filters the intake
air through a very fine paper filter lamella system. For the rea
-
son 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 carefully
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.
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.
