ASSEMBLY
WARNiNG:
Gasoline and its vapors are highly flammable and ex-
plosive. To prevent serious personal injury and property
damage, handle it with care. Keep away from ignition
sources, handle outdoors only, do not smoke while mix-
ing gasoline and lubricant together; and wipe up spills
immediately.
MiXiNG THE FUEL
See Figure 6.
The cultivator is powered by a two-stroke, air-cooled engine
and requires a fuel mixture of gasoline and -cycle fuel
lubricant.
NOTE: Always mix two-cycle engine lubricant like Ryobi’s
Exact Mix Semi Synthetic Lubricant with gasoline before
fueling the unit. Running the cultivator on gasoline alone
will ruin the engine.
Use a mixture of 50 parts unleaded regular gasoline and
1 part two-stroke engine lubricant (50:1). Use branded 87
octane (R+M+) unleaded gasoline or gasohol (maximum
10% ethyl alcohol, or 15% MTBE, no methyl alcohol.)
NOTE: Always mix lubricant and gas in the proper proportions:
.6 ounces of lubricant to one gallon of unleaded gaso-
line.
To mix the lubricant and fuel together for use:

Pour 1/ gallon of gasoline into a clean gas can or other
container approved for fuel storage. Do not mix the fuel
and lubricant directly in the cultivator’s fuel tank.
 Add .6 ounces of two-cycle engine lubricant to the
gasoline mixture.
 Add the remaining 1/ gallon of gasoline.
 Close the container holding the gas/lubricant mix and
swirl the can to blend contents together.

OXYGENATED FUELS
Some conventional gasolines are blended with alcohol or an
ether compound. These gasolines are collectively referred
to as oxygenated fuels. To meet clean air standards, some
areas of the United States and Canada use oxygenated fuels
to help reduce emissions.
If using an oxygenated fuel, make sure it is unleaded and
meets the minimum octane rating requirements. Before using
an oxygenated fuel, try to confirm the fuel’s contents. Some
states/provinces require this information to be posted on the
pump. The following are the EPA approved percentages of
oxygenates:
Ethanol (ethyl or grain alcohol) 10% by volume. You
may use gasoline containing up to 10% ethanol by volume.
Gasoline containing ethanol may be marketed under the
name “Gasohol.”
Do not use E85 fuel.
MTBE (methyl tertiary butyl ether) 15% by volume. You
may use gasoline containing up to 15% MTBE by volume.
Methanol (methyl or wood alcohol) 5% by volume. You
may use gasoline containing up to 5% methanol by volume
as long as it also contains cosolvents and corrosion inhibi-
tors to protect the fuel system. Gasoline containing more
than 5% methanol by volume may cause starting and/or
performance problems. It may also damage metal, rubber,
and plastic parts of the product or your fuel system.
If you notice any undesirable operating symptoms, try another
service station or switch to another brand of gasoline.
NOTE: Fuel system damage or performance problems re-
sulting from the use of an oxygenated fuel containing more
than the percentages of oxygenates stated previously are
not covered under warranty.
WARNiNG:
Always shut off engine before fueling. Never add fuel to
a machine with a running or hot engine. Move at least
30 ft. from refueling site before starting engine. Do not
smoke! Failure to heed this warning could result in seri-
ous personal injury.
