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.
CAUTION:
Always wear gloves when handling the bar and
chain; these components are sharp and may
contain burrs.
 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 sur-
face.
 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 post is in the long slot of the
bar.
 Replace the chain cover.
WARNING:
When placing the chain cover onto the bar,
ensure the chain tensioning pin is in the chain
tension pin hole. Failure to properly place the
chain tensioning pin in the chain tension pin
hole could cause the chain to come loose,
resulting in serious personal injury.
 Replace the washer and chain cover screw.
Tighten the chain cover screw finger tight
only. The bar must be free to move for tension
adjustment.
