WARNING:
The safety instructions in this section are to protect the
user from serious personal injury.
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
CAUTION:
Always wear gloves when handling the bar and chain;
these components are sharp and may contain burrs.
n Remove the battery pack before you do any work on the
chain saw.
n 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.
n Remove the bar and chain from the mounting surface.
n Remove the old chain from the bar.
n 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.
n 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.
