Centrifugal cleaning (Turbo)
By means of utilising the centrifugal power during the cleaning of the induction air to
the carburettor the air filter is guarantied much longer cleaning intervals.
By means of the centrifugal power the larger impurities are sorted out since they are
thrown out to the periphery of the air shell and out past the cylinder.
The air to the carburettor is captured by the ”turbo nozzle” and the finer impurities are
effectively absorbed in the air filter.
In order for centrifugal cleaning to be as effective as possible it is important that:
1. The turbo nozzle is clean from deposits.
2. The connection of the nozzle to the carburettor chamber is tight.
3. The nozzle’s guide pins are not broken. The pins are important for the correct
positioning of the nozzle in the air flow.
4. The fan shell and air conductor are cleaned.
The turbo nozzle is accessible for cleaning or replacement after the starter and air
conductor have been dismantled.
Fuel filter
The fuel filter can be taken out through
the tank’s filler hole.
Clean the filter externally if it is not too
severely fouled.
Replace the filter if necessary.
Fuel filter
On the fuel pipe in the tank there is a fuel
filter. This is accessible through the filler
hole. Pull out the filter with your fingers or
by means of tool 502 50 83-01.
Remove the tank cap completely.
If the filter is not too severely fouled it can
be cleaned externally by means of a
brush.
Otherwise it must be replaced.
Check the fuel pipe for cracking and
leakage.
NOTE!
Make sure that the filter’s connecting
collar is pressed as far as possible in the
fuel pipe.
