Idle Speed Adjustment
The cutting attachment may be moving during idle speed adjustment. Wear the
recommended personal protective equipment and observe all safety instructions. Keep
hands and body away from the cutting attachment.
When the throttle trigger is released, the engine should return to an idle speed. The correct
speed for models CG42EA, CG42EA(SL), CG51EA and CG51EA(SL) are 2300 - 2900 min
-1
,
and for others are 2700 - 3300 min
-1
(or just below the clutch engagement speed ).
The cutting attachment must not move and the engine should not stall (stop running) at
engine idle speed.
To adjust the engine idle speed, rotate the idle speed adjustment screw (A) on the
carburetor.
• Turn the idle speed screw in (clockwise) to increase the engine idle speed.
• Turn the screw out (counterclockwise) to decrease the engine idle speed.
If idle speed adjustment is necessary, and after adjustment the cutting attachment
rotates or the engine stalls, stop using the Trimmer/Brushcutter immediately!
Contact your local HITACHI dealer for assistance and servicing.
