Ryobi 725r - Manual (Page 11)

WARNING: Gasoline is extremely
flammable. Ignited Vapors may
explode. Always stop the engine and
allow it to cool before filling the fuel
tank. Do not smoke while filling the
tank. Keep sparks and open flames
at a distance from the area.
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 area outdoors. Wipe up
any spilled fuel immediately. Avoid
creating a source of ignition for spilt
fuel. Do not start the engine until fuel
vapors dissipate.
NOTE: Dispose of the old fuel/oil mix in
accordance to Federal, State, and
Local regulations.
OIL AND FUEL MIXING
INSTRUCTIONS
Old and/or improperly mixed fuel are the
main reasons for the unit not running
properly. Be sure to use fresh, clean
unleaded fuel. Follow the instructions carefully
for the proper fuel/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. It forms acids when stored. When
using alcohol-blended fuel, use fresh fuel (less
than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is
unavoidable, follow recommended precautions.
• Always use fresh fuel mix per 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.
Using Fuel Additives
The use of fuel additive, such as STA-BIL® Gas
Stabilizer or an equivalent, will inhibit corrosion
and minimize the formation of gum deposits.
Add 0.8 oz. (23 ml.) per gallon of fuel per
instructions on container. NEVER add fuel
additives directly to the unit's fuel tank. Using a
fuel additive can keep fuel for up to six (6)
months.
CAUTION: For proper engine
operation and maximum reliability,
pay strict attention to the oil and fuel
mixing instructions on the 2-cycle oil
container. Using improperly mixed
fuel can severely damage the
engine.

OIL AND FUEL INFORMATION
Thoroughly mix the proper
ratio of 2-cycle engine oil with
unleaded gasoline in a separate
fuel can. Use a 32:1 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 4 oz.
(120 ml.) bottle of RYOBI OIL makes
a 32:1 fuel/oil ratio.
