Cleaning The Air Filter - Dolmar PS-350 Owner's And Safety Manual

Cleaning the air filter

CAUTION: To prevent eye injury, always wear eye protection
when cleaning the filter with compressed air!
Do not use fuel to clean the air filter.
Unscrew the hood lock (1) counter-clockwise and remove the
hood (2).
Push up the combination switch (3) (Choke position) to prevent
dirt particles from falling into the carburetor.
Pull the air filter (4) up and out.
IMPORTANT: Cover the intake opening with a clean cloth to
prevent dirt particles from getting into the carburetor.
Choosing the right filter: The fleece filter is for use in dry or
dusty conditions. The nylon filter (available as accessory) is for
use in damp conditions.
Pry apart the top and bottom of the air filter as shown in Fig-
ure.
Cleaning the fleece filter: Carefully tap out dust or carefully
blow out dust from the inside with compressed air. Do not
brush the fleece, as this will force dirt particles into the fabric.
If the filter is very dirty, it can be washed in lukewarm water
with regular dishwashing detergent. Note that the fleece filter
does not need to be cleaned until there is a noticeable loss of
power. If cleaning the filter does not bring an improvement in
performance, it is time to replace it.
Cleaning the nylon filter: Use a soft brush or blow out dirt
from the inside with compressed air. If the filter is very dirty, it
can be washed in lukewarm water with regular dishwashing
detergent. Clean frequently (several times a day) when working
in very dusty or dirty conditions. Full engine power is possible
only with a clean air filter!
Let the air filter dry completely.
Put the top and bottom sections back together.
Before assembling the air filter, check the choke flap for any dirt
particles. If there are any, remove them with a brush.
Clean the area around the O-ring (5) at the induction opening.
If the O-ring is damaged, replace it!
CAUTION: If the air filter becomes damaged, replace imme-
diately! Pieces of cloth or large dirt particles can destroy
the engine!
Insert an air filter (4).
Push down the combination switch (3) and press the throttle
(6) all the way down one time in order to deactivate the throt-
tle lock.
Put the hood (2) back on, first guiding the two holders (7) into
their slots.
Screw the hood lock (1) back on tightly clockwise.
