BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubrica-
tion. Lubrication is provided by the automatic
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 discolor-
ation of the bar.
HELPFUL TIP
Toobtain thecorrect oilmix
ratio, pour 3.2 ounces of
2--cycle
synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on un-
leaded gasoline. Before operation, gasoline
must be mixed with a good quality synthetic
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.
2-cycle
air-cooled engine oil designed to be
mixed at a ratio of 40:1. A 40:1 ratio is ob-
tainedbymixing3.2fluidounces (95ml) ofoil
with 1 gallon (4 liters) of unleaded gasoline.
Pour the entire contents of the3.2 ounce(95
ml) container of oil into 1 gallon (4 liters) of
gasoline to achieve the proper fuel mixture.
DO NOT USE automotive or marine oil.
Theseoils willcause enginedamage. When
mixing fuel follow the instructions printed on
the container. Once oil is added to gasoline,
shake container momentarily to assure that
the fuel is thoroughly mixed. Always read
and follow the safety rules relatingto fuelbe-
fore fueling your unit.
