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 cutters must NEVER engage at engine idle speeds! If the idle speed cannot be adjusted by the procedure, described here, contact your authorized Shindaiwa servicing dealer.

Idle Speed Adjustment

1.Place the trimmer on the ground, then start the engine, and then allow it to idle 2-3 minutes until warm.

2.If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw counter-clockwise.

3.If a tachometer is available, the engine idle speed should be final adjusted to the values in the Specification section..

Operation

ŶSqueezing the throttle increases engine speed, causing the clutch to engage and operate the cutters.

ŶReleasing the throttle decreases engine speed, causing the cutters to slow, and then stop altogether as the clutch disengages.

ŶUse a sweeping motion when cutting, and vary throttle settings often.

ŶAvoid cutting material larger than 1.27 cm in diameter.
