OIL AND FUEL INFORMATION
WARNING: Remove fuel cap slowly to avoid injury
from fuel spray. Never operate the unit without the
fuel cap securely in place.
WARNING: Add fuel in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do
not start the engine until fuel vapors dissipate.
Using Fuel Additives
The bottle of 2-cycle oil
that came with your unit
contains a fuel additive
which will help inhibit
corrosion and minimize the
formation of gum deposits.
It is recom-mended 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 directly to the unit's fuel tank.
NOTE:
Dispose of the old fuel/oil mix in accordance to
Federal, State and Local regulations.
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 and leads to formation of acids during
storage. When using alcohol-blended fuel, use fresh fuel.
