Idle Speed Adjustment
See Figure 11.
If the cutting attachment turns at idle, the idle speed screw
needs adjusting on the engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the cut-
ting attachment movement. If the cutting attachment still
moves at idle speed, contact a service dealer for adjustment
and discontinue use until the repair is made.
WARNING:
The cutting attachment should never turn at idle.
Turn the idle speed screw counterclockwise
to reduce the idle RPM and stop the cutting
attachment, or contact a service dealer for
adjustment and discontinue use until the repair
is made. Serious personal injury may result
from the cutting attachment turning at idle.
