KICKBACK SAFETY PRECAUTIONS
• With a basic understanding of kickback, you can reduce
or eliminate the element of surprise. Sudden surprise
contributes to accidents. Be alert to the potential for
kickback at all times.
° Keep a good firm grip on the saw with both hands, the
right hand on the rear handle and the left hand on the
front handle, when the engine is running. Use a firm grip
with thumbs and fingers encircling the chain saw handles,
A firm grip will help you reduce kickback and maintain

WARNING: K okbaokoanheadto
dangerous ioss of
control of the chain saw and result in serious
cause of most accidents.
KICKBACK may occur when the NOSE or TIP of the
guide bar touches an object, or when wood doses in and
pinches the saw chain in the cut.
Tip contact in some cases may cause a lightning-fast
reverse reaction, kicking the guide bar up and back
toward the operator.
Any of these reactions may cause you to lose control of
the saw, which could result in serious personal injury.
K_CKBACK SPECiFiCS
Pinch Kickback
Pinch kickback can occur when the saw chain is pinched
aiong the bottom or top of the guide bar.
When pinched on the bottom of the guide bar, it may puii
the saw forward, away from the operator
When pinched aiong he top of the guide bar, it may push
the guide bar rapidiy back toward the operator.
--m- A
Rotationa_ Kickback
Rotational Kickback can occur when the moving
chain contacts an object at the upper tip of the guide
bar. This contact can cause the chain to dig into the
object, which stops the chain for an instant. The
result is a lightning fast, reverse reaction which kicks
the guide bar up and back toward the operator.

Using Blended Fuels
If you choose to use a Mended fuel or its use is unavoid-

• Always use the fresh fuel mix explained in your opera-
tor's manual
• Always shake the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the
unit
To Obtain Correct Fuel Mix:
Thoroughly mix the proper ratio of 2-cycle engine oil with
unleaded gasoline in a separate fuel can. Use a 40:1
fuel/oil ratio. Do not mix them directly in the engine fuel
tank. See the table below for specific gas and oil mixing
ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed
with one 3.2 oz. (95 ml.) bottle of
2-cycle oil makes a 40:1 fuel/oil ratio.

Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains
a fuel additive which will help inhibit corrosion and mini-
mize the formation of gum deposits. It is recommended
that you use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for
air-cooled engines along with a fuel additive, such as
STA-BIL _Gas Stabilizer or an equivalent. Add 0.8 oz.
(23 ml.) of fuel additive per gallon of fuel according to the
instructions on the container. NEVER add fuel additives
