CONTROLS
Starter
The starter is of the magnapull type with spring
return. To replace the return spring or starter cord,
contact an authorized service workshop.
Starter handle
Misuse of the starter handle can damage the starter.
Do not twist the starter cord around your hand.
Pull out the handle slowly until the gears mesh. Do
not pull out the starter cord completely and do not
let go of the starter handle when extended.
Fuel valve
The fuel valve opens and closes the connection
between the tank and the carburetor.
The illustration shows the tank valve closed; to
open, turn the lever completely to the right. There
is no middle position.
Turn off the valve when the machine is not in use
to avoid flooding the carburetor.
The fuel valve is combined with a sludge reservoir.
Choke control
The choke control opens and closes the choke
valve in the carburetor. This is only used to start a
cold engine.
The image shows the choke valve open; to close,
move the lever to the left. The midway positions
can be used. When the engine starts, the lever can
be moved gradually to the right as long as it
continues to run smoothly. Forgetting the choke is
evident as the engine runs roughly and produces
black smoke.
This also results in increased fuel consumption.
Air filter
The engine air filter consists of a foam filter and a
paper element.
The fine filter, which consists of a foam rubber pre-
filter and a paper filter cartridge, is located under
the cowling (2). The cowling can be removed by
removing the wing nut (1).
See the chapter “Maintenance/Cleaning the filter
and Replacing the air filter” for cleaning instructions.
Running the machine with a dirty air filter will cause
the engine to run similar to partial choke and show
the same symptoms as a forgotten choke
described above. It can also be difficult to start.
