FUELING ENGINE
WARNING:
Remove fuel cap slowly
when refueling.
This engine is certified to operate on
unleaded gasoline. Before
gasoline must be mixed with a good quality
2-cycle air-cooled engine oil designed to be
mix ed at a ratio of 50:1. (A 50:1 r atio is
obtained by mix ing 2.5 ounc es of oil w ith 1
gallon of unleaded gasoline). DO NOT USE
automotive or boat oil. These oils will cause
enginedamage. 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
WARNING:

To stop the engine move the switch to the
STOP position.

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 until the fuel lines and
carburetor are empty. Use fresh fuel next
season. See STORAGE section for addi-
tional information.
Use only 15"--18" of rope per pull.
Hold saw firmly while pulling starter rope.
Important points to remember
When pulling the starter rope, do not use the
full extent of the rope as this can cause the
rope to break. Do not let starter rope snap
back. Holdthe handleand let the roperewind
slowly.
