When refitting, put the auxiliary filter onto the studs so that
its sealing edges over the shoulder inside the filter
housing. Slip the prefilter over the main filter and install.
Place silencer and filter cover on the studs, fit wingnuts
and tighten down moderately.
Air Filte
The air filter's function is to intercept dust and dirt in the
combustion air and thus reduce wear on engine
components.
Clogged air filters reduce engine power, increase fuel
consumption and make starting more difficult.
The filter system consists of a prefilter, main filter and
auxiliary filter. Always clean the prefilter first if engine
power begins to drop off. It should be knocked out on the
palm of your hand or blown out with compressed air. The
prefilter can also be washed out in clean gasoline if it is
very dirty, but must be completely dry before you refit it.
For this reason we recommend that you use two prefilters
in rotation.
Always renew a dirty main filter. We do not recommend
cleaning this paper element since the results are
unsatisfactory and the risk of damaging the filter paper is
too great.
If the main filter should fail for any reason (e.g. damage),
the auxiliary filter will protect the engine from damage.
Failure of the main filter is indicated by a noticeable layer
of dirt on the flocked wire mesh of the auxiliary filter. If this
happens, clean the auxiliary filter when you change the
main filter.
As long as the main filter is in good condition there is no
need to clean the auxiliary filter as it is normally kept free
from dirt.
Close the choke shutter - move choke lever to "Choke".
Unscrew the wingnuts (1) and take off the filter cover (2)
and silencer (3). Pull the prefilter (4) off the main filter (5).
If necessary, also remove the auxiliary filter (6), knock it
out on the palm of your hand and wash it in a
non-flammable cleaning solution (warm soapy water).
