• Hold guide bar against the s aw frame mak-
ing sure the adjusting pin is aligned with
the hole in the bar. Remember this pin
moves the bar forward and backward as
screw is turned. Install the chain brake.
• Replace the chain brake nuts and tighten
finger tight. Once the chain is tensioned
you will need to tighten chain brake nuts.

Adjusting
Screw
You can adjust chain tension by loosening
the bar clamp nuts and turning adjusting
screw 1/4 of a turn while lifting up on the bar.
If chain is too tight, turn adjusting
screw 1/4 turn counterclockwise.
If chain is too loose, turn adjusting
screw 1/4 turn clockwise.
• Lift up the tip of the bar and tighten the bar
clamp nuts with the combination screw-
driver/wrench.
• Recheck chain tension. Tension is correct
when chain does not sag below the bar but
still can be moved around the bar.
_i WARNING: If the chain is operated
with a loose chain, the chain could jump off
the guide bar and result in serious injury.

CHAIN TENSION (Including units with
chain already installed)
NOTE: When adjusting chain tension,
make sure the bar nuts are finger tight only.
Attempting to tension the chain when the bar
nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the chain adjust-
ment tool (bar tool) to move the chain around
the bar. If the chain does not rotate, it is too
tight. If too loose, the chain will sag below the
bar.
Adjusting the tension:
Chah_ tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time you
use and refuel your saw.
FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good quality
2-cycle air-cooled engine oil. We
recommend Poulan or Poulan Pro(R_;brand
oil. If you do not use this oil, use a good
quality 2-cycle air-cooled eil designed to be
mixed at a ratio of 40:1 (A 40:1 ratio is
obtained by mixing 3.2 onces of oil with 1
gallon of unleaded gasoline). DO NOT USE
automotive or boat oil. These oils will cause
engine damage. When mixing fuel follow the
instructions printed on the container. Always
read and follow the safety rules listed under
HANDLE FUEL WITH CAUTION.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lu-
brication. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small amount (5 to 10%) of #1 Diesel Fuel or
kerosene. Bar and chain oil must be free
flowing for the oil system to pump enough oil
for adequate lubrication.
Genuine Poulan or Poulan ProX bar and
chain oil is recommended to protect your unit
against excessive wear from heat and
friction. Poulan or Poulan Pro(_ oil resists
high temperature thinning. If Poulan or
