Poulan Pro 3450 Operator's Manual page 6

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.
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.
S If chain is too tight, turn adjusting screw
1/4 turn counterclockwise.
S If chain is too loose, turn adjusting screw
1/4 turn clockwise.
S Lift up the tip of the bar and tighten the bar
clamp nuts with the assembly tool.
S Recheck chain tension. Tension is correct
when chain does not sag below the bar
but still can be moved around the bar.
Lifts only 1/8 of an inch from bar.

FUELING & LUBRICATION
FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before
gasoline must be mixed with a good quality
2-cycle air-cooled engine
recommend Poulan/Weed Eater 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). When mixing fuel follow
the instructions printed on the container.
Always read and follow the safety rules
relating to fuel before fueling your unit.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lu-
brication. Lubrication is provided by the au-
tomatic 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.

available, use a good grade SAE 30 oil.
S Never use waste oil for bar and chain lu-
brication.
S Always stop the engine before removing
the oil cap.
