Adjusting Engine Idle
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.

Idle Speed Adjustment
1. Place the trimmer on the ground, then
start the engine. Allow it to idle 2-3
minutes until warm.
2. If the cutting attachment rotates when
the engine is at idle, reduce the idle
speed by turning the idle speed screw
(A) counter-clockwise; clockwise to
increase idle speed
3. If a tachometer is available, idle
speed screw (A) should be set to
the specications found on the
“Specications” page of this manual.
WARNING!
When carburetor adjustment is completed, the cutting attachment should not move at idle,
otherwise serious personal injury may result. If the idle speed cannot be adjusted by the procedure
described here, return the trimmer to your Shindaiwa dealer for inspection.
