OPERA
TION
Starting the Engine (continued)
WARNING!
Never start the engine from the oper-
ating position.
WARNING!
The cutting attachment may rotate
when the engine is started!
When the Engine Starts...
■ After the engine starts, allow the en-
gine to warm up at idle 2 or 3 minutes
before operating the unit.
■ After the engine is warm, pick
up the unit and clip on the shoulder
strap or harness if so equipped.
See page 11.
■ 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).
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.
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.)
Figure 19
Idle the engine briefly before stopping
(about 2 minutes), then slide the igni-
tion switch to the “O” (OFF) position.
See Figure 20.

7. Operating the throttle will
automatically disengage the fast
idle setting.

Engine Idle Adjustment
The engine must return to idle speed
whenever the throttle lever is re-
leased. Idle speed is adjustable, and
must be set low enough to permit the
engine clutch to disengage the cut-
ting attachment when the throttle is
released.
WARNING!
The cutting attachment must NEVER
rotate at engine idle! If the idle
speed cannot be adjusted by the pro-
ceedure described here, have the unit
inspected at an authorized Shindaiwa
dealer.
1. Place the unit on the ground, then start
the engine and allow it to idle for 2-3
minutes until warm.

Adjusting Screw
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 21.
3. If a tachometer is available, the engine
idle speed should be final adjusted to
3,000 (±250) rpm (min -1 ).
NOTE:
Carburetor fuel mixture adjustments are
preset at factory on units with emission
control systems and cannot be serviced
in the field.
