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

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 thor-

oughly with soap and water. Let dry

and reassemble the element.
Store the unit in a clean, dust-free

area.

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:

Prime the primer bulb until no more

1.

fuel is passing through.
Start and run the engine until it

2.

stops running.
Repeat steps 1 and 2 until the en-

3.

gine 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 resulting from stale or contami-

nated fuel is not covered by the Shindaiwa

warranty policy.

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.

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.

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.

Adjusting Engine Idle

The engine must return to idle speed

whenever the throttle lever is re-

leased. Idle speed is adjustable, and

must be set low enough to permit the

engine clutch to disengage the cutting

attachment.

Idle Speed Adjustment

Place the trimmer on the ground,

1.

then start the engine, and then

allow it to idle 2-3 minutes until

warm.
If the attachment moves when the

2.

engine is at idle, reduce the idle

speed by turning the idle adjust-

ment screw counter-clockwise.

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.

NOTE

Carburetor fuel mixture adjustments are

preset at factory and cannot be serviced

in the field
