Operation Manual

Starting / Stopping the engine - Starting settings and start-up, - Engine will not start

ENGLISH 25

[Basic settings (chain brake, standard or winter operation, stop switch, primer) as described in

the previous paragraph. ]

Cold start:

• Pull the choke lever (7) (this also activates the part-throttle setting) [part throttle control

pin (8) is pulled along].

• Using the starter handle, start the engine until you hear it briefly ignite.

Note: the engine cannot start up and continue running while the choke lever is pulled

out.

! After the first audible ignition, immediately:

• Press the choke lever back in again.

• Continue starting until the engine runs

• The engine is then running in part throttle (visible from the part throttle control pin).

• Briefly operate the throttle control to cancel the part control setting (the part throttle

control pin jumps back in again).

• The engine will then continue to run at idle speed.

Note: If the choke lever is not pushed back in when you hear the first audible ignition, the combustion

chamber can quickly become saturated if start-up is repeated with the choke lever pulled out. In this

case you will be unable to start the device. Please refer to the instructions given in section 5.3,

“Engine will not start”.

Warm start:

Start the engine in idle setting with the choke not pulled out,

or start it in !

part throttle setting:

• by pulling the choke out and pressing it back in again [the part throttle setting is

activated as a result, which is visible from the pulled-out part throttle control pin (8)]

• Start the engine until it runs, then briefly operate the throttle control to cancel the part

throttle setting (the part throttle control pin jumps back in again).

• The engine then runs on at idle speed.

5.3 Engine will not start

If the engine fails to start after several attempts, check whether all adjustments described above have

been correctly carried out, particularly that the stop switch is not in the "0" position. Try starting once

again. The combustion chamber will be flooded, if the engine still fails to start.

In that case we recommend you proceed as follows:

• Remove the cowl. (chapter. 3.4)

• Pull the spark plug cap off the spark plug.

• Remove the spark plug and dry fuel mixture from the electrodes.

• Move the throttle lever up to full throttle. Pull the starter handle several times (with removed spark

plug) to clear the combustion chamber.

• Move the throttle lever down to idling position, refit the spark plug, the plug cap and the cowl.

• Repeat the starting process according to the starting settings for a warm start in part throttle

setting.
