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 cyclone filter and a fine filter.

Air is drawn in through the screen (3) on the cyclone filter and coarser pollutants collect in the container

(4).

The fine filter, which consists of a foam rubber pre- filter and a paper filter cartridge, is located under the cowling (2). The cowling and the cyclone filter can be removed by removing the wing nut (1).

See the chapter “Maintenance/Cleaning the cyclone filter and Replacing the air filter” for cleaning instructions.

Running the machine with a dirty air filter will cause the engine to run on partial choke and show the same symptoms as a forgotten choke described above. It can also be difficult to start.
