Cleaning The Air Þ Lter - Dolmar PS-350 S Instruction Manual

Cleaning the air Þ lter
CAUTION: To prevent eye injury, always wear eye protection
when cleaning the Þ lter with compressed air!
Do not use fuel to clean the air Þ lter.
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 Þ lter (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 Þ lter: The ß eece Þ lter (available as acces-
sory) is for use in dry or dusty conditions. The nylon Þ lter is for
use in damp conditions.
Pry apart the top and bottom of the air Þ lter as shown in Fig-
ure.
Cleaning the ß eece Þ lter: Carefully tap out dust or carefully
blow out dust from the inside with compressed air. Do not
brush the ß eece, as this will force dirt particles into the fabric.
If the Þ lter is very dirty, it can be washed in lukewarm water
with regular dishwashing detergent. Note that the ß eece Þ lter
does not need to be cleaned until there is a noticeable loss of
power. If cleaning the Þ lter does not bring an improvement in
performance, it is time to replace it.
Cleaning the nylon Þ lter: Use a soft brush or blow out dirt
from the inside with compressed air. If the Þ lter 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 Þ lter!
Let the air Þ lter dry completely.
Put the top and bottom sections back together.
Before assembling the air Þ lter, check the choke ß ap 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 Þ lter becomes damaged, replace imme-
diately! Pieces of cloth or large dirt particles can destroy
the engine!
Insert an air Þ lter (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, Þ rst guiding the two holders (7) into
their slots.
Screw the hood lock (1) back on tightly clockwise.
