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.
WARNING!
The cutting attachment must NEVER move at engine idle! If the
idle speed cannot be adjusted by the procedure described here, return the
unit to your Shindaiwa dealer for inspection.
Idle Speed Adjustment
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 counterclockwise.
3.
If a tachometer is available, adjust idle. Check Specifications page for
correct idle speed.
Loading Trimmer Line
1. Cut one piece of line to recommended length.
2. Align arrows on top of knob with openings in eyelets.
3. Insert one end of trimmer line into an eyelet, and push
line equal distance through trimmer head.
4. Hold trimmer head while turning knob clockwise to wind
