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” position. See Figure 19. (If the engine stops after the initial start, close the choke and restart.)
Choke Control (open position)
WARNING!
Never start the engine from the operating position.
7.Operating the throttle will automatically disengage the fast idle setting.
IMPORTANT!
If the engine fails to start after several attempts 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 troubleshooting section of this manual.
When the Engine Starts...
After the engine starts, allow the engine 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 12.
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).

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 procedure 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

Adjusting Screw

2.If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw
3.If a tachometer is available, the engine idle speed should be final adjusted to 3,000 (±250) RPM
NOTE:
Carburetor fuel mixture adjustments are pre- set at factory on units with emission control systems and cannot be serviced in the field.
