Choosingtherightlter:
The eece lter is for use in dry or dusty
conditions. The nylon lter is for use in damp conditions.
Pry apart the top and bottom of the air lter as shown in Fig-
ure.
Cleaningtheeecelter:
Carefully tap out dust or carefully
blow out dust from the inside with compressed air. Do not
brush the eece, as this will force dirt particles into the fabric.
If the lter is very dirty, it can be washed in lukewarm water
with regular dishwashing detergent. Note that the eece lter
does not need to be cleaned until there is a noticeable loss of
power. If cleaning the lter does not bring an improvement in
performance, it is time to replace it.
Cleaningthenylonlter,thenylonlter
in thelterhood
andpre-lter: Use a soft brush or blow out dirt from the inside
with compressed air. If the 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 lter!
Noteonthepre-lter:
The ventilation slots (2a) can be covered
by an additional self-adhesive nylon pre-lter. Before putting
on this lter, clean the area where it will go. This pre-lter is
available as an accessory part.
Let the air lter dry completely.
Put the top and bottom sections back together.
Before assembling the air lter, check the choke ap for any dirt
particles. If there are any, remove them with a brush.

the engine!
