ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can
cause injury.
Installing and Removing Saw Chain (Fig. A–D)

WARNING: Sharp moving blade. To prevent accidental
operation, insure that battery is disconnected from the handle
before performing the following operations. Failure to do this
could result in serious personal injury.

CAUTION: Sharp moving blade. Always wear protective
gloves when installing or removing the chain. The chain is
sharp and can cut you when it is not running.
1. Place the pole saw on a firm surface. Rotate the two
hex head screws counterclockwise with the hex
12
wrench 16 provided.
2. Remove sprocket cover
head screws.
3. To remove the saw chain
tension screw 19 in the front of the housing using the
flat screwdriver end of the wrench. Turning the screw
counterclockwise allows the guide bar
reduces the tension on the chain so that it may be removed.
4. Lift the worn saw chain out of the groove in the
guide bar.
5. Flip guide bar over.
6. To replace the saw chain, check to make sure that the
slot in the guide bar is over the location pins
Figure D and that hole below the slot is located over the
adjustment pin.
7. Place new chain in groove of guide bar and around
sprocket. Make sure saw teeth are facing correct direction by
matching the graphic on housing or guide bar.
8. Rotate the chain tension screw
saw housing clockwise to increase the chain tension.
9. Replace sprocket cover, bar clamp, and hex head screws.
10. Follow the instructions in the section Adjusting
Chain Tension.
Adjusting Chain Tension (Fig. A, C, E, F)
1. With the pole saw still on a firm surface check the saw
chain 14 tension. The tension is correct when the saw
chain snaps back after being pulled 1/8" (3 mm) away from
the guide bar 13 with light force from the middle finger
and thumb as shown in Figure E. There should be no "sag"
between the guide bar and the saw chain on the underside
as shown in Figure F.
2. To adjust saw chain tension, loosen hex head
screws 12 .
3. Rotate the chain tension screw
housing using the flat screwdriver end of the wrench.
4. Do not over-tension the saw chain as this will lead to
excessive wear and will reduce the life of the guide bar and
saw chain. Overtensioning also reduces the amount of cuts
you will get per battery charge.

6. When the saw chain is new check the tension frequently
(after disconnecting battery) during the first 2 hours of use
as a new chain stretches slightly.
nOTE: Saw chain tension should be adjusted regularly.
Saw Chain and Guide Bar Oiling (Fig. G)
Auto Oiling System
This pole saw is equipped with an auto oiling system that
keeps the saw chain and guide bar constantly lubricated.
The oil level indicator 25
chain saw. If the oil level is less than a quarter full, remove
the battery from the pole saw and refill with the correct
type of oil.
nOTE: Always empty oil tank when finished cutting.
nOTE: Use a high quality bar and chain oil for proper chain
and bar lubrication. As a temporary substitute, a non-
detergent SAE30 weight motor oil can be used. The use of
a vegetable based bar and chain oil is recommended when
pruning trees. Mineral oil is not recommended because it
may harm trees. Never use waste oil or very thick oil. These
may damage your pole saw.
Filling the Oil Reservoir
• Remove the oil cap 17
recommended bar and chain oil until the oil level has
reached the top of the oil level indicator
• Refit the oil cap.
• Periodically switch the chain saw off and check the
oil level indicator to ensure the bar and chain are being
properly oiled.
Transporting Pole Saw (Fig. A)
Always remove the battery pack
the saw chain with the scabbard

the pole saw.
Joining Saw Head Module to Handle Module
(Fig. H–K)

WARNING: Sharp moving blade. To prevent accidental
operation, insure that battery is disconnected from the handle
and that the protective scabbard is in place on the chain
before performing the following operations. Failure to do this
could result in serious personal injury.
The three assemblies which make up the pole saw are
keyed to insure correct assembly. If an assembly does not
smoothly attach to another do not force fit.
Combining the handle assembly
assembly creates a pole saw that is approximately
3
6' (1.8 m) in length as shown in Figure H.
To attach the handle assembly to the saw head assembly:
1. Align the groove 21 on the outside of the coupling
end of the handle assembly
inside of the coupling end of the saw head assembly
Refer to Figure I. Push the two sections completely together.
Refer to Figure J.
2. Slide the threaded sleeve
down as far as possible and rotate the sleeve clockwise
until it stops and completely covers the threads as shown
in Figure K.

WARNING: Always check to make sure that the sleeve
is completely threaded on and that the red threads are no
longer visible. Not threading the sleeve completely on could
result in the assemblies becoming disconnected, creating a
