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
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.
5. Once saw chain tension is correct, tighten hex head
screws 12 to clamp bar.
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.

Transporting Pole Saw (Fig. A)
Always remove the battery pack

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 assembliess 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 3 creates a pole saw that is approximately 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
end of the handle assembly
on the inside of the coupling end of the saw head
assembly 3 . 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 assemblys becoming
disconnected creating a hazardous condition.
Periodically check the connections to insure that no
red threads are visible.
