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.

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(Fig. K).
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).

4. Place the guide bar on the mounting surface by
sliding the guide-bar slot over the alignment bulges,
making sure that the tension 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 tensioning screw
properly until the tension pin is located exactly in the hole.
5. Reassemble the chain-sprocket cover, insert the bar
nut through its mounting hole, and tighten it with
the combi-wrench to ensure that the guide bar is
installed in place.
6. Tension the chain by following the section
"ADJUSTING THE CHAIN TENSION".
7. Hold the tip of the guide bar up and tighten the
chain-sprocket-bar nut securely.
NOTICE: To extend the guide bar life, invert the bar
occasionally.
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 bar nut to finger tight.
3. Hold the bar nose up, and adjust the tensioning
screw until the following points apply (Fig. N):
◾
Chain sag in the center of the bar is around:1.3mm
(Fig. O).
◾
Wear gloves, ensure chain can be pulled along the
bar smoothly with two fingers.
4. After finishing chain tension adjustment, Hold the bar
nose up and tighten the bar nut.
NOTICE: If chain sag in the center of the bar is not
around 1.3 mm, readjust chain tension.
SPROCKET IN GUIDE BAR LUBRICATION
The guide bar has a sprocket at its tip. It must be
lubricated weekly with chain oil injected into the
lubricating hole by a grease syringe (not included) to
extend the guide bar life (Fig. P). Turn the guide bar and
check that the lubrication holes and chain groove are free
from impurities.

TRANSPORTING AND STORING
1. Do not store or transport the pole saw attachment
when it is running. Always remove the battery pack
before storing or transporting.
2. Always place the guide bar sheath on the guide bar
and chain before storing or transporting the pole saw
attachment. Use caution to avoid the sharp teeth of
the chain.
3. Clean the pole saw thoroughly before storing. Store
the pole saw indoors, in a dry place that is locked
and/or inaccessible to children and keep away from
corrosive agents such as garden chemicals and de-
icing salts.
4. If the pole saw attachment is removed from the power
head and stored separately, fit the end cap on the
attachment shaft to avoid dirt getting into the coupler.
Protecting the environment
Do not dispose of electrical equipment,
battery charger and batteries/
rechargeable batteries into household
waste!
