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 cutters.
Adjusting Engine Idle
WARNING!
The cutters must NEVER engage at engine idle speeds! If the idle speed cannot be
adjusted by the above procedure, return the trimmer to your Shindaiwa dealer for
inspection.
Idle Speed Adjustment
1. Start the engine, and then allow it to idle 2–3 minutes until warm.
2. If the cutters move when the engine is at idle, reduce idle speed by turning the
idle adjustment screw (A) counterclockwise.
3.
If a tachometer is available, adjust idle. Check Specifications page for correct
idle speed
4. Carburetor fuel mixture adjustments are preset at the factory and cannot be
adjusted or 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 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.
■
Remove the spark plug and pour
about 7 cc (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 thoroughly. Reassemble the
element.
■
Store the unit in a clean, dust-free
area.
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.
