chain-sprocket cover is facing upwards.
3. Wear gloves. Using the dual-head wrench provided,
loosen the cover screw to remove the screw and the
chain-sprocket cover. Clean the chain-sprocket cover
with a dry cloth and save it for reassembly (Fig. H).
4. Remove the bar and chain from the mounting
surface. Remove the worn chain from the bar.
NOTICE:
If there is difficulty in removing the bar and chain
from the mounting surface, place the pole saw upright, with
one hand support the bar, to loosen the chain-tensioning
screw counterclockwise with the other hand (Fig. I) and
then remove the bar with the chain.
NOTICE:
This is a good time to inspect the drive sprocket
for excessive wear or damage.
Assembling the New Bar and Chain
1. Lay the new saw chain in a loop on a flat surface and
straighten any kinks (Fig. J).
2. 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. K).

K-1 Chain Drive Links
K-2 Guide-bar Groove
3. Hold the chain in position on the guide bar and place
the loop around the sprocket of the pole saw.
NOTICE:
Small directional arrows are engraved in the
saw chain. Another directional arrow is molded into the
tool body (Fig. L). When looping the saw chain onto the
sprocket, make sure that the direction of the arrows on the
saw chain will CORRESPOND to the direction of the arrow
on the tool body. If they face in opposite directions, turn
over the saw chain and guide bar assembly (Fig. M).

L-5 Guide-bar Slot
4. Place the guide bar on the mounting surface by
sliding the guide bar slot over the alignment bulges,
making sure that the tension adjusting pin is inserted
in the lower hole in the tail of the bar (Fig. L).
NOTICE:
If there is difficulty in inserting the tension
adjusting pin into the hole, adjust the chain-tensioning
screw properly until the tension adjusting pin is located
exactly in the hole.
5. Replace the chain-sprocket cover and the cover
screw. Slightly tighten them.
6. Remove all the slack from the chain by turning the
chain-tensioning screw clockwise until the chain
seats snugly against the guide bar with the drive
links in the guide bar groove and lift the tip of the
guide bar to check for sag. Release the tip of the
guide bar and turn the chain-tensioning screw
once clockwise. Repeat this process until the sag is
eliminated (Fig. N).
7. Hold the tip of the guide bar up and tighten the
chain-sprocket-cover screw securely.
NOTICE:
To extend the guide bar life, invert the bar
occasionally.
NOTICE:
If chain is too tight, it will not rotate. Loosen the
chain-sprocket-cover screw slightly and turn the tensioning
screw 1/4 turn counterclockwise. Lift the tip of the guide
bar and retighten the chain-sprocket-cover screw securely.
Assure that the chain will rotate without binding.
ADJUSTING THE CHAIN TENSION
CAUTION:
The saw chain must be properly tensioned
before using.
1. Stop the motor and remove the battery pack before
adjusting the chain tension.
2. Loosen the cover screw to finger tight.
3. Turn the chain-tensioning screw clockwise to
tension the chain. See the "REPLACING THE BAR
AND CHAIN" section in this manual for additional
information.
◾
A cold chain is correctly tensioned when there is
no slack on the underside of the guide bar and the
chain is snug, but it can be turned by hand without
binding. The chain must be re-tensioned whenever
the flats on the drive links do not sit in the bar
groove (Fig. O).
◾
During normal saw operation, the temperature of
the chain will increase. The drive links of a correctly
tensioned warm chain will hang approximately
1.3mm out of the bar groove (Fig. P).
NOTICE:
New chains tend to stretch; check chain tension
frequently and tension as required.
NOTICE:
A chain tensioned while it is warm may be too
tight upon cooling. Check the cold tension before next use.
