Replacing Bar And Chain - Ryobi RCS1825Li15 Operator's Manual

REPLACING BAR AND CHAIN

See Figures 23 - 27.
WARNING:
Remove the battery pack from the chain saw and
make sure the chain has stopped before you do
any work on the saw. Failure to do so may result
in accidental starting and possible serious injury.
WARNING:
The safety instructions in this section are to protect
the user from serious personal injury.
CAUTION:
Always wear gloves when handling the bar and
chain; these components are sharp and may
contain burrs.
WARNING:
Never touch or adjust the chain while the motor is
running. The saw chain is very sharp; always wear
protective gloves when performing maintenance
to the chain to avoid possible serious lacerations.
 Remove the battery pack before you do any work
on the chain saw.
 Remove the hex key from the storage area and
use it to remove the chain cover screw, washer
and chain cover from the chain saw.
 Remove the bar and chain from mounting
surface.
 Remove the old chain from the bar.
 Lay out the new saw chain in a loop and
straighten any kinks. The cutters should face in
the direction of chain rotation. If they face the
opposite direction, turn the loop over.
 Place the chain drive links into the bar groove.
Position the chain so there is a loop at the back
of the bar. Hold the chain in position on the bar
and place the loop around the sprocket of the
chain saw. Fit the bar flush against the mounting
surface so that the bar stud is in the long slot of
the bar.
NOTE: When placing the bar on the bar stud,
assure that the adjusting pin is in the chain
tension pin hole.
