HELPFUL TIP
Toobtain thecorrectoilmix
ratio, pour 3.2 ounces of
2--cycle synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality synthetic 2-cycle air-
cooled engi ne oil designed tobe mixed at ara-
tio of 40:1. Poulan/WEED EATER brand syn-
thetic oi l is r ecommended. A 40:1 ratio is
obtained by mixing 3.2 ounces (95 ml) of oil
with 1 gallon (4 liters) of unleaded gasoline.
Included with t his saw is a 3 .2 ounce (95 ml)
containerof Poulan/WEEDEA TER b rand syn-
thetic oi l. Pour the entire contents of this con-
tainer into 1 gal lon (4 l iters) of gasoline to
achievetheproperfuel mixture. DO NOTUSE
automotive or marine oil. These oils will
causeenginedamage. Whenmixing fuelfol-
low theinstructions printed onthe container.

under HANDLE FUEL WITH CAUTION.
BAR AND CHAIN L UBRICATION
The bar and chain r equire 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
shownbysmokecomingfromthechainand/
or discoloration of thebar.
In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small am ount(5 to10%)of #1DieselFuel or
kerosene. Bar and chain oil must be free
flowingfortheoilsystemtopumpenoughoil
for adequate lubrication.
Genuine Poulan bar and chain oil is recom-
mended to protect your unit against exces-
sive wear from heatand friction. Poulan oil
resists hightemperature thinning.
If Poulan barand chain oil is notavailable,
use a goodgrade SAE 30 oil.

cation.
S Always stop the engine before removing
the oil cap.
