Cleaning: Cleaning: Rinse off coarse dirt in running water.
Knead a capful MAKITA lter cleaner (Order No. 980 008 627
into the foam material of the pre-lter (1, Order No. 395 173
090) until it suds up well.
Rinse out pre-lter thoroughly in running water.
Let the pre-lter dry thoroughly.
In order to ensure full ltration effectiveness, air-lter
oil must be used with the pre-lter. Wet the pre-lter
with a capful (about 20 ccm) of MAKITA air-lter oil
(Order No. 980 008 628, biodegradable).
Knead the pre-lter to evenly distribute the oil. Then
squeeze out any excess oil.
NOTE: If using other air-lter oils, follow the manufacturer’s
instructions.
If cleaning is not possible on-site, have spare pre-lters on
hand (Order No. 395 173 090).
To insert the pre-lter in the lter cover, position it so it ts the
space in the cover and then press it in (5). The pre-lter must
t completely and cover all parts of the lter space, without
leaving any spaces unltered.
Inner lters (all models)
Wash out the dirty inner lter (3, Order No. 395 173 020)
in lukewarm soapy water with regular dishwashing liquid or
MAKITA lter cleaner (Order No. 980 008 627).
Let the inner lter dry thoroughly.
Air lter insert (paper cartridge, all models)
The air lter insert (2, Order No. 395 173 010) lters the intake
air through a very ne paper lter lamella system. For the rea-
son the cartridge must never be washed. Clean the air lter
insert once a week.
To clean the air lter insert, spread it out slightly and carefully
tap it against a clean surface.
Replace the air 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 lter 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 lter! Never clean out the air lter with compressed air! Do
not clean the pre-lter and inner lter with fuel.
The service life of the engine depends on the condition and regular maintenance of the lter elements. Failure to
perform maintenance and cleaning at the prescribed intervals will cause increased wear inside the engine!
If the air 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 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-lter (dry foam)
Only for models DPC6340-7341
If the pre-lter (1, Order No. 395 173 080) is dirty, wash
it out in lukewarm water with standard dishwashing liquid
or MAKITA lter cleaner (Order No. 980 008 627). If using
MAKITA lter cleaner, proceed as described after the text
section "Cleaning".
Let the pre-lter dry thoroughly.
NOTE: The pre-lter must be cleaned daily, or several times
daily if working under dusty conditions. If cleaning is not
possible on-site, have spare pre-lters on hand. Replace the
pre-lter at least every 25 operating hours.
To improve ltration effectiveness, the pre-lter can be wet-
ted with air-lter oil. Before adding air-lter oil, carefully
wash the lter with air-lter cleaner. Care for the oiled air
lter as described for DPC8131, 8132.
To insert the pre-lter in the lter cover, position it so it ts
the space in the cover and then press it in (5). The pre-lter
must t completely and cover all parts of the lter space,
without leaving any spaces unltered.
