Choosing the right
Þ
lter:
The
ß
eece
Þ
lter is for use in dry or
dusty conditions. The nylon
Þ
lter (available as accessory) is for
use in damp conditions. The pre-
Þ
lter keeps out sawdust, and
prevents powder snow from getting in when working in winter.
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!
Cleaning the pre-
Þ
lter:
When the pre-
Þ
lter becomes dirty, wash
it in lukewarm soapy water using standard dishwashing liquid.
Let the air
Þ
lter
dry completely
.
Put the top and bottom sections back together.
Place the pre-
Þ
lter back in the cover.
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 imme-
diately! Pieces of cloth or large dirt particles can destroy
the engine!
