Carburetor Adjustment

Engine Break-In

New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be made. During the break-in period, your engine performance will increase and exhaust emissions will stabilize. Idle speed can be adjusted as required.

High Altitude Operation

This engine has been factory adjusted to maintain satisfactory starting, emission, and durability performance up to 1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above 1,100 feet ASL the carburetor may need to be adjusted by an authorized Shindaiwa service dealer.

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.

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.

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 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, the engine idle speed should be final adjusted to the values in the Specification section.

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.

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 procedures to prepare it for storage:

■■Clean external parts thoroughly.

■■Drain all the fuel from the carbure- tor 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 carburetor 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 caused by stale or con- taminated fuel is not covered by the Shindaiwa warranty policy.

■■Remove the spark plug and pour about 7 ml (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 interior 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 thoroughly with soap and water, let dry and reassemble the element.

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