Oil And Fuel Information - Ryobi 510r Operator's Manual

RECOMMENDED OIL TYPE
Using the proper type and weight of oil in
the crankcase is extremely important.
Check the oil before each use and change
the oil regularly. Using incorrect or dirty oil can cause
premature engine wear and failure.
Use a high-quality SAE 30 weight oil of API (American
Petroleum Institute) service class SF, SG, SH.
ADDING OIL TO CRANKCASE – INITIAL USE
NOTE: This unit is shipped without oil. In order to avoid
damage to the unit, put oil in the crankcase
before attempting to start unit.
Your unit is supplied with one 3.4 fluid oz. (100 ml.)
bottle of SAE 30 SF, SG, SH oil (Fig. 5).
NOTE: Save the bottle to measure the correct amount
for future oil changes. See Changing the Oil.
NOTE: Your new 4-Cycle cultivator is shipped for
operation in conditions above 40°F (4°C). For
cold weather operation, where temperatures
plummet below 40°F (4°C), use a high-quality
SAE 10W30 weight oil of API (American
Petroleum Institute) service class SF, SG, SH.
1. Unscrew the oil bottle top and remove the paper seal
covering the opening. Replace the top and cut the
tip off the funnel spout (Fig. 5).
2. Place the unit on a flat level surface with the
cultivator in a horizontal position (Fig. 6).
3. Remove the oil plug / dipstick from the crankcase
(Fig. 7).
4. Pour the entire bottle of oil into the oil fill hole
(Fig. 8).
NOTE: Never add oil to the fuel or fuel tank.
5. Remove the tag from oil fill plug / dipstick.
6. Wipe up any oil that may have spilled and reinstall
the oil fill plug / dipstick.
The importance of checking and maintaining the proper
oil level in the crankcase cannot be overemphasized.
Check oil before each use and change as specified in
the Maintenance Schedule.

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper
unit performance. Be sure to use fresh,
clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid
damage to the unit, do not mix oil with gasoline.
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 form acids when stored.
When using alcohol-blended fuel, use fresh fuel that is
less than 60 days old.
Using Blended Fuels
If you choose to use a blended fuel, or if its use is
unavoidable, follow recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL
• Drain tank and run the engine dry before storing unit
