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.
1.  Place the unit on the ground, then 

start the engine and 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.

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.
