Stopping The Engine; Adjusting Engine Idle; Operation - Shindaiwa 89309 Owner's/Operator's Manual

Starting the engine (continued)
When the motor starts...
1. Open the choke by moving the choke
lever backward (toward the fuel tank).
2. If the engine does not continue to run,
repeat the appropriate cranking proce-
dures for a cold or warm 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
see the "10 - 15 Hour Maintenance"
section.

Stopping the engine

1. Cool the engine by allowing it to idle for
2–3 minutes.
2. Move the ignition switch to the "O" or
STOP position.

Adjusting engine idle

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 cutters must NEVER
engage at engine idle speeds! If the
idle speed cannot be adjusted by the
procedure, described here, contact
your authorized Shindaiwa servicing
dealer.

Operation

Squeezing the throttle increases
engine speed, causing the clutch to
engage and operate the cutters.

3. When the engine starts, clear excess
fuel from the combustion chamber by
accelerating the engine several times
with the throttle lever.
4. Operating the throttle will automatically
disengage the fast idle setting.
3. With the spark plug removed, 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 wrench. If a
torque wrench is available, torque the
spark plug to the values in the "Specifi-
cations" section.
5. Repeat the starting procedures for a
warm engine.
CAUTION!
Incorrect spark plug installation can
damage the engine!

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.
3. If a tachometer is available, the engine
idle speed should be final adjusted to
the values in the Specification section..
NOTE
Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced
Releasing the throttle decreases
engine speed, causing the cutters to
slow, and then stop altogether as the
clutch disengages.
If the engine does not start
Repeat the appropriate starting proce-
dure for a cold or warm engine.
If the engine still fails to start, use the
procedures for "Starting a flooded
engine.".
