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.
Disengage the cover clasp (1) with the universal wrench and
take off the cover (2).
Push up the combination switch (3) (Choke position) to prevent
dirt particles from falling into the carburetor.
Unhook the clasp (4) in the direction of the arrow with a finger
or the universal wrench.
Pull the air filter (5) up and out.
Take the pre-filter (5a) out of the cover (2).
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. The pre-filter keeps out sawdust, and
prevents powder snow from getting in when working in winter.
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!
Cleaning the pre-filter: When the pre-filter becomes dirty, wash
it in lukewarm soapy water using standard dishwashing liquid.
Let the air filter dry completely.
Put the top and bottom sections back together.
Place the pre-filter back in the cover.
Before assembling the air filter, check the choke flap for any dirt
particles. If there are any, remove them with a brush.
CAUTION: If the air filter becomes damaged, replace imme-
diately! Pieces of cloth or large dirt particles can destroy
the engine!
Insert the air filter (5) and press the clasp (4) in the direction of
the arrow until it engages.
Move the combination switch (3) down and press the throttle (6)
once all the way, to deactivate the half-throttle lock.
Put the cover (2) back on and affix it with the cover clasps
(1).
