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