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

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.
