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.
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.
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.

■
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.
■
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
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.
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.
