CARE AND MAINTENANCE
11. Replacing the Bar and Chain
WARNING
• Always wear protective gloves when handling the
bar and chain; these components are sharp and
may contain burrs.
• Never touch or adjust the chain while the motor
is running.
NOTICE:
When replacing the guide bar and chain,
always use the specified bar and chain combination
listed in this manual.
Disassembling the Worn Bar and Chain
a. Remove the battery, allow the saw to cool and
tighten the oil tank cap.
b. Position the chainsaw on its side on a firm,
flat surface, so that the side cover is facing
upwards.
c. Rotate the side-cover knob counterclockwise
one turn, then turn the chain-tensioning knob
towards the front handle as far as it will go to
loosen the chain.
d. Rotate the side-cover knob counterclockwise,
then remove the side cover. Clean the side
cover with a dry cloth (Fig. 11a).
e. Remove the bar and saw chain from the
mounting surface. Remove the worn chain from
the bar.
NOTICE:
This is a good time to inspect the drive
sprocket for excessive wear or damage.
Assembling the New Bar and Chain
a. Remove the battery, allow the saw to cool, and
tighten the oil tank cap.
b. Lay the new saw chain in a loop on a flat surface
and straighten any kinks. The cutters should
face in the direction of chain rotation, if they face
backwards, turn the loop over. (Fig. 11b & 11c).
c. Place the chain-drive links into the guide-bar
groove. Position the chain so there is a loop at
the back of the guide bar (Fig. 11d).
d. Place the loop around the sprocket of the
power head.
