FUELING & LUBRICATION
WARNING:
Remove fuel cap slowly
when refueling.
FUELING ENGINE
This engine is certified to operate on un-
leaded gasoline. Before operation, gasoline
must be mixed with a good quality synthetic
2-cycle air-cooled engine oil designed to be
mixed at a ratio of 40:1. Snapper
t
orPoulan/
Weed Eater
r
brand synthetic oil is recom-
mended. Mix gasoline and oil at a ratio of
40:1. 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 this saw is
a 3.2 ounce container of oil. Pour the entire
contents of this container into 1gallon of gas-
oline to achieve the proper fuel mixture.
DO N O T U SE automotive oil or boat oil. These
oils will cause engine damage. When mixing
fuel, follow instructions printed on container.
Once oil is added to gasoline, shake container
momentarily to assure that the fuel is thorough-
ly mixed. Always read and follow the safety
rules relating to fuel before fueling y our unit.
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 o il 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 Snapper
t
bar and chain oil is recom-
mended to protect y our unit against excessive
wear fr om heat and friction. Snapper
t
oil re-
sists high temperature thinning.
If Snapper
t
bar and chain oil is not avai lable,
use a good gr ade SAE 30 oil.
S
Never use waste oil for bar and chain lubri-
cation.
S
Always stop the engine before removing
the oil cap.
IMPORTANT
Experience indicates that alcohol--blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage for 30
days or longer. Drain the gas tank, start the
engine and let it run unt il the fuel lines and
carburetor are empty. Use fresh fuel next
season. See STORAGE section for addi-
tional information.
STARTING
WARNING:
The chain must not
move when the engine runs at idle speed. If
the chain moves at i dle speed refer to CAR-
BURETOR ADJUSTMENT within this
manual. Avoid contact with the muffler. A hot
muffler can cause serious burns.
To stop the engine move the ON/STOP
switch to the STOP position.
To start the engine hold the saw firmly on
the ground as illustrated. Make sure the
