OPERATION
ADDING BAR AND CHAIN LUBRICANT
See Figure 3.
Use RYOBI Bar and Chain Lubricant. It is designed
for chains and chain oilers, and is formulated to
perform over a wide temperature range with no dilu-
tion required. Chain saw should use approximately
one tank of lubricant per tank of fuel.
NOTE: Do not use dirty, used, or otherwise con-
taminated lubricants. Damage may occur to the
oil pump, bar, or chain.

Carefully pour the bar and chain lubricant into
the oil tank.

Fill the oil tank every time you fuel the engine.
OPERATING THE CHAIN BRAKE
See Figures 4 - 5.
Check the operating condition of the chain brake
prior to each use.

Engage the chain brake by rotating your left
hand around the front handle, allowing the back
of your hand to push the chain brake lever/hand
guard toward the bar while the chain is rotating
rapidly. Be sure to maintain both hands on the
saw handles at all times.

Reset the chain brake back into the RUN posi-
tion by grasping the top of the chain brake lever/
hand guard and pulling toward the front handle
until you hear a click.
WARNING:
If the chain brake does not stop the chain
immediately, or if the chain brake will not stay
in the run position without assistance, take the
saw to an authorized service center for repair
prior to use.
NOTICE:
Before each use, check to make sure that the
chain is properly tensioned. A cold chain is cor-
rectly tensioned when there is no slack on the
underside of the guide bar, the chain is snug,
and it can be turned by hand without binding.
During normal saw operation, the temperature
of the chain increases. The drive links of a cor-
rectly tensioned warm chain will hang approxi-
mately .050 in. out of the bar groove.
See the
Adjusting the Chain Tension
instruc-
tions in the
Maintenance
section of this manual
to properly adjust the chain tension.

past the chain line.

Place the chain saw on level ground and ensure
that no objects or obstructions are in the imme-
diate vicinity that could come in contact with the
bar and chain.
