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 engine
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
cutting 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 flooded
with fuel. If flooding is suspected,
move the choke lever to the open position
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” position. See
Figure 18. (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.
Idle Speed Adjustment
WARNING!
The cutting attachment must
NEVER rotate at engine 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 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. See Figure 20.
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 adjustments are
preset at factory and cannot be serviced
in the field.
