Air filter maintenance

Contaminated air filters cause a
reduction in engine performance and increase fuel
consumption with more pollutants in the exhaust
gas. Engines are less likely to start readily with a
contaminated air filter.
As a basic principle therefore, the air filter should
be cleaned as follows before starting work, and
intermittently in very dusty conditions:
Before opening the air filter, close the choke
prevent dirt entering the carburettor.
 Push tab (a) in, only slightly open air filter lid
(11) and remove by rotating gently back and
forth
 Remove foam filter (c) from the lid and clean
the area around the filter.
 Thoroughly clean air filter casing (d) and air
filter cover (11) on the inside, using a
paintbrush or by carefully blowing on them.
 Clean filter insert (c) by shaking it out or
carefully blowing on it.
If the filter insert is damaged or so contaminated
that it is impossible to clean, replace it with the
original spare part (part no. 20 48 406).
 Insert the new or cleaned foam filter into the air
filter lid.
 Position the air filter cover with both tabs (b)
[inside, opposite tab (a)] in the corresponding
two pockets (b') of the filter casing.
 Press air filter cover against the filter casing
until tab (a) clicks audibly into place.

Replacing the fuel filter

We recommend having the fuel filter (34) changed
annually by a specialised service centre.
(schematic diagram)
A trained mechanic can carefully remove the fuel
filter via a wire loop through the fuel tank filler.
Ensure that the thicker part of the fuel hose on the
tank wall is not drawn into the fuel tank.
