Centrifugal cleaning (Active)

Mod. 650, 700
Considerably longer cleaning intervals for the air filter are achieved by using the
centrifugal force during the filtering of the intake air to the carburettor.
By means of using the centrifugal force the heavier impurities are thrown out towards
the periphery of the air spiral and on past the cylinder.
The air to the carburettor is taken up by the centrifugal cleaning nozzle and the finer
impurities are effectively captured in air filter.
For centrifugal cleaning to be as efficient as possible it is important that:
1. The centrifugal cleaning nozzle is clean from deposits.
2. The connection of the nozzle to the carburettor chamber is tight.
3. The nozzle attachments are not broken.
4. The fan spiral and air conductor are clean.
The centrifugal cleaning nozzle is accessible for cleaning or replacement after
dismantling the starter unit and air conductor.
When the filter and covers are fitted it is
very important to make sure that all the
seals are undamaged and correctly
positioned.
Seals which do not seal properly result in
less efficient centrifugal cleaning and ra-
pid blockage of the air filter.
Increased wear on the piston and cylin-
der barrel as a result of inferior air cleaning
shortens the engine's service-life.
