Starting the Engine (continued)
WARNING!
The cutting attachment may rotate
when the engine is started!
6. When the engine starts, slowly move
the choke lever to the "OPEN" posi-
tion. See Figure 19. (If the engine stops
after the initial start, close the choke
and restart.)

Engine Idle Adjustment
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 when
the throttle is released.
Idle Speed Adjustment
WARNING!
The cutting attachment must NEVER
rotate at engine idle! If the idle speed
cannot be adjusted by the proceedure
described here, have the unit inspect-
ed at an authorized Shindaiwa dealer.
1. Place the unit on the ground, then start
the engine and allow it to idle for -3
minutes until warm.

WARNING!
Never start the engine from the oper-
ating position.
7. Operating the throttle will automatically
disengage the fast idle setting.
IMPORTANT!
If the engine fails to start after several at-
tempts with the choke in the closed posi-
tion, 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 troubleshoot-
ing section of this manual.
Idle the engine briefly before stopping
(about minutes), then slide the igni-
tion switch to the "O" (OFF) position.
See Figure 0.

. If the attachment rotates when the
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise.
See Figure 1.
When the Engine Starts
n After the engine starts, allow the en-
gine to warm up at idle or 3 minutes
before operating the unit.
n After the engine is warm, pick
up the unit and clip on the shoulder
strap or harness 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 below).
3. If a tachometer is available, the engine
idle speed should be final adjusted to

systems and cannot be serviced in the field.
