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.
1
The fuel valve is combined with a sludge
reservoir.
Choke control
8011-186
The choke control opens and closes the
1. Fuel valve
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
1
consumption.
Air filter
8011-183
The engine air filter consists of a foam filter
1. Choke Control
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
1
can be removed by removing the wing nut (1).
See the chapter ìMaintenance/Cleaning the
filter and Replacing the air filterî 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
2
be difficult to start.
