Starting A Cold Engine – Restarting After Refueling

WARNING!

The cutter attachment must never oscillate at engine idle speed. If the idle speed cannot be adjusted by the procedures described here, return the trimmer to your Shindaiwa dealer for inspection.

The engine must return to idle speed whenever the throttle trigger is released. Idle speed is adjustable and must be set low enough to permit the engine clutch to disengage the cutter attachment when throttle trigger is released.

or three minutes, or until it warms up.

IMPORTANT!

Use a tachometer, if one is available, to set engine idle. Standard idle speed is:
