Adding bar and Chain Oil: initial Use

This unit comes from the factory with the chain oil reservoir
empty. Refer to Adding Bar and Chain Oil instructions in the
Maintenance section.

Adjusting the Chain Tension: initial Use

The saw chain must be properly tensioned before attempting
to start or operate the unit. The saw chain may also require
additional tensioning as the saw chain heats up during operation.
Refer to Adjusting the Chain Tension instructions in the
Maintenance section.
Testing the Chain Brake

Always activate the chain brake slowly and deliberately. Keep
the saw chain from touching anything. Do not let the chain saw
tip forward.
Always test the chain brake before using the unit.
1. Set the unit on a flat, level surface.
2. Make sure the chain brake lever is pulled back in the
disengaged position (Fig. 1).

Oil and fuel Mixing instructions

The use of old and/or improperly mixed fuel is the most common
cause of performance problems. Use only fresh, clean unleaded
gasoline. Follow the instructions carefully for the proper gasoline/
oil mixture.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs
water. As little as 1% water in the fuel can make fuel and oil
separate, forming acids when stored. ALWAYS use fresh fuel (less
than 30 days old).

Dispose of old fuel according to federal, state and local
regulations.
Using Blended Fuels
If using a blended fuel:
– Always use the fresh fuel mix explained in your operator's
manual.
– Use the fuel additive STA-BIL® or an equivalent.
– Always agitate the fuel mix before fueling the unit.
– Drain the tank and run the engine dry before storing the unit.

DO NOT use E85 fuel in this chainsaw.

DO NOT use E15 fuel in this chainsaw.
E15 fuel – gasoline that is comprised of 15% ethanol is
not legal for use in outdoor power equipment. Using fuel
containing greater than 10% ethanol will damage this engine
and void the warranty. Always use E10 or less to protect the
engine's power.
Using Fuel additives
Always use a 2-cycle oil designed for air-cooled engines and
mix it with a fuel additive, such as STA-BIL Fuel Stabilizer or an
equivalent. Add 0.8 oz. (23mL) of fuel additive per gallon of fuel,
according to the instructions on the container. NEVER add fuel
additives directly to the unit's fuel tank.


When fueling or using your chainsaw, a fire extinguisher should
be available.
