IDLE SPEED ADJUSTMENT
See Figure 21.
If the chain turns at idle, the idle speed screw needs ad-
justing on your trimmer engine. Turn the idle speed screw
counterclockwise to reduce the idle RPM and stop the chain
movement. If the saw chain still moves at idle speed, contact
a service dealer for adjustment and discontinue use until the
repair is made.
WARNING:
The saw chain should never turn at idle. Turn the idle
speed screw counterclockwise to reduce the idle RPM
and stop the chain, or contact a service dealer for ad-
justment and discontinue use until the repair is made.
Serious personal injury may result from the saw chain
turning at idle.
