Figure 18

WARNING!

Never start the engine from the oper- ating position.

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 troubleshooting section of this manual.

When the Engine Starts...

nAfter the engine starts, allow the en- gine to warm up at idle 2 or 3 minutes before operating the unit.

nAfter the engine is warm, pick

up the unit and clip on the shoulder strap. See page 12.

nAdvancing 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).

Stopping the Engine

OFF

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.
