Cleaning the air filter
STOP
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.
Unhook the filter hood clips (1) with the combination tool and
remove the filter hood (2).
Pull out the choke (3) to prevent dirt particles from getting into
the carburetor.
Unhook the air filter retainer (4) by pressing in the direction
shown by the arrow.
Pull the air filter (5) 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 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, the nylon filter in the filter hood
and pre-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!
Note on the pre-filter: The ventilation slots (2a) can be covered
by an additional self-adhesive nylon pre-filter. Before putting
on this filter, clean the area where it will go. This pre-filter is
available as an accessory part.
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.
CAUTION: If the air filter becomes damaged, replace im-
mediately! Pieces of cloth or large dirt particles can destroy
the engine!
Put in the air filter (5) and press down the air filter retainer (4)
evenly with thumb and forefinger until it clicks.
Push in the choke (3) and push the throttle all the way in to
deactivate the half-throttle lock.
Put on the filter hood (2) and hook in the clips (1).
