Dolmar PC-6412 S Instruction Manual page 21

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 (dry foam)
Only for models PC-6412 S - 7314 S
If the pre-Þ lter (1, Order No. 326 173 080) is dirty, wash it
out in lukewarm water with standard dishwashing liquid or
DOLMAR Þ lter cleaner (Order No. 980 008 127). If using
DOLMAR Þ lter cleaner, proceed as described after the text
section "Cleaning".
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 improve Þ ltration effectiveness, the pre-Þ lter can be wet-
ted with air-Þ lter oil. Before adding air-Þ lter oil, carefully
wash the Þ lter with air-Þ lter cleaner. Care for the oiled air
Þ lter as described for PC-8114 and PC-8116.
To insert the pre-Þ lter in the Þ lter cover, 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.
Pre-Þ lter (foam with air-Þ lter oil)
Only for models PC-8114 and 8116
Clean or replace (when cutting with high dust amounts):
• Daily
or at least every
• 4 operating hours, or
• 8 tank Þ llings, or
• 8 litres fuel mixture.
Clean or replace (when cutting wet, or when cutting steel):
• weekly
or at least every

Cleaning: Cleaning: Rinse off coarse dirt in running water.
Knead a capful DOLMAR Þ lter cleaner (Order No. 980 008 127)
into the foam material of the pre-Þ lter (1, Order No. 326 173
090) until it suds up well.
Rinse out pre-Þ lter thoroughly in running water.
Let the pre-Þ lter dry thoroughly.
In order to ensure full Þ ltration effectiveness, air-Þ lter
oil must be used with the pre-Þ lter. Wet the pre-Þ lter
with a capful (about 20 ccm) of DOLMAR air-Þ lter oil
(Order No. 980 008 128, biodegradable).
Knead the pre-Þ lter to evenly distribute the oil. Then
squeeze out any excess oil.
NOTE: If using other air-Þ lter oils, follow the manufacturer's
instructions.
If cleaning is not possible on-site, have spare pre-Þ lters on
hand (Order No. 326 173 090).
To insert the pre-Þ lter in the Þ lter cover, 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 (all models)
Wash out the dirty inner Þ lter (3, Order No. 394 173 020)
in lukewarm soapy water with regular dishwashing liquid or
DOLMAR Þ lter cleaner (Order No. 980 008 127).
Let the inner Þ lter dry thoroughly.
Air Þ lter insert (paper cartridge, all models)
The air Þ lter insert (2, Order No. 394 173 010) Þ lters the intake
air through a very Þ ne paper Þ lter lamella system. For the rea-
son 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 carefully
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.
