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 rotate 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.If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw
3.If a tachometer is available, adjust idle. Check Specifications page for correct idle speed
NOTE:
Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field.

In order to keep the blade in balance, all cutting edges must be sharpened equally.
WARNING!
Sharpen only the cutting teeth of a blade. DO NOT alter the contour of the blade in any way.
Multiple-tooth Circular Blade
Use a round file to maintain a radius of
0.04to 1 to 1.5 mm (0.06”) at the base of each tooth. Cutting edges must be offset equally on each side.
