WARNING
CAUTION
Every unit is test run at the factory and the carburettor is fine
tuned for maximum performance.
Before adjusting carburettor, clean or replace air filter, start en-
gine and run several minutes to bring it to operating temperature.
The engine must return to idle speed whenever the throttle lever
is released. Idle speed is adjustable, and must be set low enough
to permit the engine clutch to disengage the cutting attachment.
To adjust the carburettor proceed as follow:
1.
Place the unit on the ground, then start the engine, and then
allow it to idle 2-3 minutes until warm.
2.
If the attachment moves when the engine is at idle, reduce
the idle speed by turning the idle adjustment screw(T) coun-
ter-clockwise.
3.
Repeat the process of accelerating to full throttle and return
to idle a few times. Check that the cutting attachment stops
moving at idle.
4.
If a tachometer is available, the engine idle speed should be
final adjusted to the settings recommended in the Specifica-
tions section.
NOTE
Carburettor fuel mixture adjustments are preset at factory and
cannot be serviced in the field.
