SAW CHAIN REPLACEMENT/INSTALLA-
TION
1.
Remove the bar retaining nuts and screw. Then take
off the sprocket cover (Fig. 4A).
2. Using a straight screwdriver turn tension adjustment
screw counterclockwise (Fig. 4B) as far as it will go
or to the end of its travel, take off the chain then
remove the bar.
3. Prepare new chain or bar.
4.
Loop the saw chain over the drive sprocket with the
cutting edges of the chain pointing in the direction of
rotation (Fig. 4C).
5.
Adjust the tension adjustment screw (Fig. 4B) to
allow insertion of the bar (Fig. 4C). Make sure the
chain follows the slot in the guide bar and adjust the
tension adjustment screw to make the chain tighten.
6.
Install the sprocket cover and tighten bar retaining
nuts and screw (Fig. 4A).

SAW CHAIN TENSION ADJUSTMENT
Proper tension of the saw chain is extremely important
and must be checked before starting, as well as during,
any cutting operation. Taking the time to make needed
adjustments to the saw chain will result in improved
cutting performance and prolonged chain life.
NOTE: A new chain and bar will need readjustment after
as few as 5 cuts. This is normal during the break-in peri-
od, and the interval between future adjustments will
lengthen quickly (Fig. 5).
TO ADJUST THE SAW CHAIN TENSION:
1.
Loosen the bar retaining nuts so they are hand tight
(Fig. 4a).
2.
Holding the nose of the bar up, use the screwdriver or
scrench (if provided in your unit’s hardware pack) to
turn the guide bar adjustment screw clockwise to
tighten the chain (Fig. 4b). Turning the screw coun-
terclockwise loosens the chain on the guide bar.
3.
While wearing heavy duty work gloves (after you’ve
made the adjustment), move the saw chain back and
forth on the guide bar to be sure the chain moves
freely and is in proper mesh with the sprocket. Never
move the chain with your bare hands.
NOTE: IF the chain is difficult to rotate or if it binds on the
guide bar, there is too much tension applied and it must be
adjusted. To decrease tension, turn the adjustment screw
counterclockwise, slowly. Move the chain back and forth
until it moves freely.
4.
Holding the nose in upper position, securely tighten
the bar retaining nuts.
•
OILING THE CHAIN
The pole saw chain is self-lubricating. Oil is dispersed
onto the chain as the unit is used. Keep an adequate
amount of oil in the oil tank. Use the bar-chain oil
provided in the hardware pack. Always use bar-chain and
sprocket oil or similar chain saw oil.
•
GUIDE BAR MAINTENANCE
NOTE: Proper maintenance of the guide bar is essential
to the performance of your pole saw. Proper guide bar
maintenance will keep your saw in good working order.
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Incorrect filing and non-uniform cutter and depth gauge
settings cause most guide bar problems, primarily
resulting in uneven bar wear. As the bar wears unevenly,
the rails widen, which may cause chain clatter and
difficulty in making straight cuts.
Insufficient guide bar lubrication and operating the saw
with a chain that is too tight will contribute to rapid bar
wear. Refer to Saw Chain Tension Adjustment.
To help minimize bar wear, the following guide bar
maintenance is recommended:
•
BAR WEAR
Turn guide bar frequently at regular intervals (for
example, after 5 hours of use), to ensure even wear on
top and bottom of bar.

DRIVE SHAFT
Installing the lower shaft
1. Remove the hanger from the lower shaft (A). Press
the release lever (B) while pushing the lower shaft into
the tool-link couping. (Fig. 2A)
2. Locate and lock the release lever into the primary hole
(C) in the shaft. (Fig. 2A)
3. Tighten the knob (D) securely clockwise before using
the unit. (Fig. 2B)

TRIMMING A TREE (PRUNING)
Avoid kickback. Kickback can result in severe injury or
death.
Do not operate the pole saw while in a tree, on a ladder
or any other unstable work surface, or in any awkward
position. You may lose control of the pole saw causing
severe injury.
Do not extend your arms above shoulders when using
the pole saw. Seek professional help if you are facing
conditions beyond your ability.
Trimming a tree is the process of cutting limbs from a
living tree. Make sure your footing is firm. Keep your feet
apart. Divide your weight evenly on both feet.
TO TRIM A LIMB (PRUNING):
1.
Make the first cut six inches from tree trunk on the
underside of the limb. Use the top of the guide bar
to make this cut. Cut a third of the way through the
diameter of the limb (Fig. 3).
2.
Move two to four inches farther out on the limb.
Make the second cut from above the limb. Continue
the cut until you cut the limb off.
3.
Make the third cut as close to the tree trunk as
possible on underside of limb stub. Use the top of
the guide bar to make this cut. Cut a third through
the diameter of stub.
4.
Make the fourth cut directly above the third cut. Cut
down to meet the third cut. This will remove the
limb stub.

CAUTION: Make sure the release lever is
locked in the primary hole and knob is securely
tightened before operating this unit.
CAUTION: All attachments are designed to be
used in the primary hole unless otherwise indi-
cated in the specific attachment’s operator’s
manual. If the incorrect hole is used, it could
result in injury, or damage to the unit.
OPERATING INSTRUCTIONS
WARNING: Kickback may occur when the
nose or tip of the guide bar touches an
object, or when the wood closes in and
pinches the saw chain in the cut. Tip contact
in some cases may cause a lightning-fast
reverse action, kicking the guide bar rapidly
back towards the operator. Pinching the saw
chain along the top of the guide bar may
push the guide bar rapidly back towards the
operator. Either of these reactions may cause
you to lose control of the saw, which could
result in serious injury to the user.
WARNING: Do not rely exclusively upon the
safety devices built into your saw. As a chain
saw user, you should take several steps to
keep your cutting jobs free from accident or
injury.
