Makita DPC6410 Instruction And Safety Manual page 23

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 (dry foam)
Only for models DPC6410 - 7321
If the pre-filter (1, Order No. 326 173 080) is dirty, wash
it out in lukewarm water with standard dishwashing liquid
or MAKITA filter cleaner (Order No. 980 008 627). If using
MAKITA filter cleaner, proceed as described after the text
section "Cleaning".
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 improve filtration effectiveness, the pre-filter can be wet-
ted with air-filter oil. Before adding air-filter oil, carefully
wash the filter with air-filter cleaner. Care for the oiled air
filter as described for DPC8111 and DPC8112.
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.
Pre-filter (foam with air-filter oil)
Only for models DPC8111 and 8112
Clean or replace (when cutting with high dust amounts):
• Daily
or at least every
• 4 operating hours, or
• 8 tank fillings, or
• 8 litres fuel mixture.
Clean or replace (when cutting wet, or when cutting steel):
•
weekly
or at least every
• 25 operating hours, or
• 50 tank fillings, or
• 55 litres fuel mixture.
Cleaning: 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. 326 173
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. 326 173 090).
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. 394 173 020)
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. 394 173 010) 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.
