Engine Idle
Checking and Adjusting
The engine must return to idle speed
whenever the throttle lever is released.
Engine idle speed is adjustable and must
be properly set to permit the clutch shoes
to disengage from the clutch drum. The
correct engine idle speed also provides air
flow to maintain engine cooling.
Idle Adjustment Procedure
1. Start the engine and allow it to idle for
two to three minutes until it warms up.
After the engine starts or fires–
1. Open the choke by moving the choke
lever down (toward the fuel tank).
. If the engine stops, repeat the starting
procedure previously described.
3. When the engine starts, clear excess
fuel from the combustion area by
revving the engine several times with
the throttle lever.
WARNING!
The trimmer head will rotate as the
engine accelerates!
IMPORTANT!
Operating the throttle will automatically
disengage the fast idle setting.
If the engine does not start–
Repeat the appropriate starting procedures
for a hot or cold engine. If the engine
still fails to start, use the procedure for
"Starting a Flooded Engine."
1. Let the engine idle for a period of two
to three minutes to allow engine to cool
and temperature to stabilize.
. Slide the ignition switch to the "O"
(STOP) position.
. If the cutting attachment rotates at
engine idle speed, turn the idle
speed adjustment screw counter-
clockwise until the cutting attachment
stops turning.
3. If a tachometer is available, the engine
idle speed should be final-adjusted to
3000 rpm ±50 rpm (min
-1
WARNING!
The cutting attachment must
NEVER rotate at engine idle speeds!
If the idle speed cannot be adjusted
by the above procedure, return the
trimmer to your Shindaiwa dealer for
inspection.
CAUTION!
Carburetor mixture adjustments are
set at the factory and cannot be
serviced in the field.
Starting a Flooded
Engine
1. Disconnect the spark plug boot and
unscrew the spark plug using the spark
plug wrench provided with the unit
(turn counterclockwise to remove).
. If the spark plug is fouled with carbon
or coated with fuel, clean or replace the
spark plug as necessary. For spark plug
specifications and gapping procedure,
refer to page 11.
3. Crank the
engine several
times to clear
excess fuel from
the combustion
chamber,
making sure
that the choke
is open and the
ignition switch is
in the "O"
(STOP) position.
CAUTION!
Incorrect spark plug installation can
result in serious engine damage!
4. Install the spark plug and tighten same
using the spark plug wrench provided
with the unit. If a torque wrench is
available, torque the spark plug to 148-
165 inch-pounds (170-190 kg/cm).
5. Repeat the starting procedures for a
warm engine.
6. If the engine still fails to start or fire,
refer to the troubleshooting chart at the
