Starting the Engine (continued)
WARNING!
Never start the engine from
the operating position.
WARNING!
The cutting attachment may
rotate when the engine is
started!
When the Engine Starts
n After the engine starts, allow the en-
gine to warm up at idle 2 or 3 minutes
before operating the unit.
n After the engine is warm, pick
up the unit and clip on the shoulder
strap if so equipped. See page 11.
n Advancing the throttle makes the cut-
ting attachment turn faster; releasing
the throttle permits the attachment to
stop turning. If the cutting attachment
continues to rotate when the engine
returns to idle, carburetor idle speed
should
be adjusted (see "Adjusting Engine
Idle" below).
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be ooded
with fuel. If ooding is suspected,
move the choke lever to the open posi-
tion and repeatedly pull the recoil starter
to remove excess fuel and start the
engine. If the engine still fails to start,
refer to the troubleshooting section of
this manual.
5. When the engine starts, slowly move
the choke lever to the "OPEN" posi-
tion. See Figure 20. (If the engine
stops after the initial start, close the
choke and restart.)

Open
Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the “O” (Engine OFF) position.

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 cutting attachment
must NEVER rotate at en-
gine idle! If the idle speed cannot be
adjusted by the procedure described
here, return the trimmer to your
Shindaiwa dealer for inspection.
1. Place the trimmer on the ground,
then start the engine, and allow it to
idle 2-3 minutes until warm.
2. If the attachment rotates when the en-
gine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise.
See Figure 22.
3. If a tachometer is available, the
engine idle speed should be final
adjusted to 2,750 (
±
250) rpm (min
-1
).
4. Carburetor fuel mixture adjustments
are preset at factory and cannot be
serviced in the field.
