Adjusting Engine Idle

Idle Adjusting
Screw
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
trimmer to your Shindaiwa dealer for
inspection.
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 rotates when the
engine is at idle, reduce the idle
speed by turning the idle adjustment
screw counter-clockwise. See Figure
20.
3. If a tachometer is available, the engine
idle speed should be final adjusted to
3,000 (±250) rpm (min-1).
4. Carburetor fuel mixture adjustments
are preset at factory and cannot be
serviced in the field.
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.
Long Term StorageWhenever the unit will not be used for
30 days or longer, use the following
procedures 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 stops 2.
running.
Repeat steps 1 and 2 until the engine 3.
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
contaminated fuel is not covered by the
Shindaiwa warranty policy.
