3-5. SAW CHAIN TENSION
ADJUSTMENT
Proper tension of the saw chain is extr-
emely 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
period, and the interval between future
adjustments will lengthen quickly
(Figure 3-5A).
CAUTION
If a chain is TOO LOOSE or TOO
TIGHT, the bar chain and saw bearings
will wear more rapidly.Study Figure
3-5A for information concerning correct
cold tension (A), correct warm tension
(B), and as a guide for when saw chain
needs adjustment (C).
TO ADJUST SAW CHAIN
TENSION:
4. Loosen the bar retaining nuts (D) so
they are hand tight. (See Fig.3-5B)
2. Holding the nose of the bar up, use
the screwdriver or scrench if
provided in your User's Kit to turn
the guide bar adjustment screw (E)
(Fig.3-5C) clockwise to tighten the
chain. Turning the screw COUNTER-
CLOCKWISE LOOSENS THE
CHAIN on the guide bar.
3. After adjustment and while wearing
heavy duly work gloves, move the
saw chain back and forth on the
guide bar to be sure the chain
moves freely and is in proper mesh
with sprocket.Do not move chain
with bare hands.
NOTE: IF the chain is difficult to rotate
or if it binds on the guide bar, too much
tension has been applied and 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 (70 inch ibs.)

3: 6. ASSEMBLY OF POLE SAW
. Make sure the unit is unplugged
from power source.
2. Slip handle bracket (A) over chain
saw handle (B) from the right side
{See Fig.3-6A).NOTE: The trigger
must be depressed before the bra-
cket will go onto the handle. Push
the tock-off button and depress the
trigger. While holding the trigger in,
place the trigger support portion of
the bracket under the trigger and
slide the bracket onto the chain saw
handle. The bracket will keep the
trigger in the "ON"position.

s in handle bracket. Install Phillips
head screws with lock washers thro-
ugh pole bracket from left side and
thread into theweld nuts on the han-
dle bracket. Tighten screws securely.
