Air Filter
Disassembly of air filter
The air filter is designed to retain the dirt in the air, which
is sucked into the ingine, in order to reduce the wear of the
moving parts.
A dirty air filter will cause a loss in the power of the engine,
it will increase the fuel consumption and make starting
more difficult.
Therefore clean air filter daily!
Close choke shutter before removing the air filter in order
to prevent dirt from entering the carburetor, which is posi-
tioned behind the air filter. Loosen the cylinder head screw
with the combination wrench and remove the cover and
the air filter which is a felt" plate ".
To clean the air filter tap filter lightly onto the palm of your
hand dirty side down or clean it with a soft brush and then
wash it in straight gasoline.
If air filter is badly clogged it must be replaced by a new one
because even a careful cleaning will show only temporary
results.
