CHAIN TENSION (Including units with
chain already installed)
NOTE: When adjusting chain tension,
make sure the chain brake nuts are finger
tight only. Attempting to tension the chain
when the chain brake nuts are tight can
cause damage.
Adjusting the tension:
Chain 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.
S
An adjusting screw (located on the guide
bar) is used to adjust the tension of the
chain (see illustration). Turn adjusting
screw clockwise until chain solidly con-
tacts bottom of guide bar rail.

S Use the screwdriver end of the bar tool to
move chain around guide bar.
S If chain does not rotate, it is too tight.
Slightly loosen bar clamp nuts and loosen
chain by turning the adjusting screw. Re-
tighten bar clamp nuts.
S If chain is too loose, it will sag below the
guide bar. DO NOT operate the saw if the
chain is loose.
WARNING: If the saw is operated
with a loose chain, the chain could jump off
the guide bar and result in serious injury.
FUELING & LUBRICATION
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 oil 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 lubri-
cation. 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 Pro R bar and
chain oil is recommended to protect your unit
against excessive wear from heat and
friction. Poulan or Poulan Pro R oil resists
high temperature thinning. If Poulan or
Poulan Pro R bar and chain oil is not
available, use a good grade SAE 30 oil.
S
Never use waste oil for bar and chain lubri-
cation.
