Idle the engine briefly before stopping 

(about 2 minutes), then slide the igni-

tion 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.

Place the trimmer on the ground, 

1. 

then start the engine, and then allow 

it to idle 2-3 minutes until warm.
If the attachment rotates when the 

2. 

engine is at idle, reduce the idle 

speed by turning the idle adjustment 

screw counter-clockwise.
If a tachometer is available, the engine 

3. 

idle speed should be final adjusted to 

3,000 (±300) rpm (min

-1

).

Carburetor fuel mixture adjustments

are preset at factory and cannot be 

serviced in the field.

WARNING!
The cutting attachment 

must NEVER rotate at engine idle! 

If the idle speed cannot be adjusted
