Adjusting 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. 2500 rpm, but the running-in process of a new engine may require slight readjustment of the idling speed. Adjustments to the adjusting screws (L) and (H) may only be made by an authorised MAKITA service center. Accordingly, the holes for the two screws are sealed shut. 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 3 - 5 minutes). Adjust the carburetor with the screwdriver (1, Order No. 944 340 001) 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, tighten the screw a little. Switch off the engine 20

Adjusting
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.
2500 rpm, but the running-in process of a new engine may
require slight readjustment of the idling speed.
Adjustments to the adjusting screws (L) and (H) may only
be made by an authorised MAKITA service center. Accor-
dingly, the holes for the two screws are sealed shut.
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 3 - 5
minutes).
Adjust the carburetor with the screwdriver (
1
, Order No. 944
340 001) 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, tighten the screw a little.
Switch off the engine
