IMPORTANT!!

If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when operating the engine below 1,100 feet ASL, otherwise severe engine damage may result.

NOTE:

Every unit is run at the factory and the carburetor is set in compliance with emission regulations. Carburetor adjustments, other than idle speed, must be performed by an authorized Shindaiwa dealer.

Adjusting Engine Idle

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 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 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

Long Term Storage

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

■■Clean external parts thoroughly and apply a light coating of oil to all metal surfaces.

■■Drain all the fuel from the carburetor and 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.

CAUTION!

Gasoline stored in the carbure-

tor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.

IMPORTANT!

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

NOTE

Damage resulting from stale or con- taminated fuel is not covered by the Shindaiwa warranty policy.

■■Remove the spark plug and pour about 1/4 oz. of engine oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the inte- rior of the engine. Reinstall the spark plug.

■■Before storing the unit, repair or replace any worn or damaged parts.

■■Remove the air cleaner element from the carburetor and clean it thor- oughly with soap and water. Let dry and reassemble the element.

■■Store the unit in a clean, dust-free area.
