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 main-
tenance 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 posi-
tion 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 ten-
sion pin hole.
