the carburetor

NOTE: The grinding parts are equipped with an electronic 

ignition to limit the speed. 
At the factory the idling speed has been set to approx. 

2,500 1/min., but the running-in process of a new engine 

may require slight readjustment of the idling speed.

A

For correct adjustment of the idling speed the following 

steps must be carried out:

Start the engine and run it until it is warm

  (about    -  5  

minutes).

B

Adjust the carburetor with the screwdriver (

1

, Order No. 944 

40 00) included with the Power Cut. It has a lug that helps 

with adjustment.

Readjust the idling speed.

If the cut-off disc is still turning when the engine is running, 

unscrew the adjusting screw of the throttle valve (

2

) until the 

cut-off disc is no longer turning. When the engine is left running 

at idling speed, loosen the screw a little.

Switch off the engine.
