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.

Long Term Storage

Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage:

■■Clean external parts thoroughly.

■■Drain all the fuel from the carbure- tor and the fuel tank.

IMPORTANT!!

All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL.

CAUTION!

Gasoline stored in the carburetor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.

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 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, 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.

■■Remove remaining fuel from the fuel lines and carburetor with the fuel drained from the fuel tank. To do so:

1.Prime the primer bulb until no more fuel is passing through.

2.Start and run the engine until it stops running.

3.Repeat steps 1 and 2 until the engine will no longer start.

■■Remove the spark plug and pour about 7 mL (¼ oz.) of 2-cycle mix- ing oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug.
