Starting a Flooded Engine

WARNING!
Burn danger from hot engine!
Allow engine to cool before
removing cylinder cover.
1. Disconnect the spark plug lead, and
then use the spark plug wrench to
loosen and remove the spark plug.
2. If the spark plug is fouled or is
soaked with fuel, clean or replace
the plug as necessary. For spark
plug specifications and gapping
procedure, see page 19.
3. With the spark plug removed, and
the ignition switch off, crank the
engine several times to clear
excess fuel from the combustion
chamber.

4. Replace the spark plug and tighten
it firmly with the spark plug

available, torque the spark plug to
148-165 inch-pounds (170-190 kg/
cm).
5. Replace the cylinder cover.
CAUTION!
Incorrect spark plug installation
can damage the engine!
6. Repeat the starting procedures for
a warm engine.
7. If the engine still fails to start or
fire, refer to the troubleshooting
chart at the end of this manual.

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
cutters.

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 counterclockwise.
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 adjust-
ments are preset at the factory and
cannot be serviced in the field.
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.

1. Cool the engine by allowing it to
idle for 2–3 minutes.
2. Move the ignition switch to the "O"
or STOP position.
Operation
■ Squeezing the throttle increases
engine speed, causing the clutch to
engage and operate the cutters.
■ Releasing the throttle decreases
engine speed, causing the cutters
to slow, and then stop altogether as
the clutch disengages.
■ Use a sweeping motion when
cutting, and vary throttle settings
often.
■ Avoid cutting material larger than
1/2 inch in diameter.
