■ If the engine starts, runs, and accelerates but will
not idle, turn the idling speed screw "T" clockwise to
increase idling speed.
■ If the chain turns at idle, turn the idling speed screw
"T" anticlockwise to reduce the idle RPM and stop the
chain movement. If the saw chain still moves at idling
speed, contact a Ryobi service dealer for adjustment
and discontinue use until the repair is made.
WARNING
The saw chain should never turn at idle. Turn the idling
speed screw "T" anticlockwise to reduce the idle RPM
and stop the chain, or contact a Ryobi service dealer
for adjustment and discontinue use until the repair is
made. Serious personal injury may result from the saw
chain turning at idle.
OPERATING THE CHAIN BRAKE
See figure 25 - 26.
Refer to "Safety" earlier in this manual for additional
information. Check the operating condition of the chain
brake prior to each use.
1. Start the engine and grasp the front and rear handles

to Ryobi service dealer for repair and discontinue use
until the repair is made.
3. Reset the chain brake back into the run position (B) by
grasping the right-hand side (from operator's position)
of the chain brake lever/hand guard and pull towards
the front handle until you hear a click.
