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. Failure to use the correct oil, or using 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 being filled with 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
Pg. 14.
1. Unscrew the top of the bottle of oil and remove the
paper seal covering the opening. Replace top. 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 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 needed. See
Changing the Oil Pg. 14.

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for the unit not
running properly. 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.
Use fresh fuel (less than 60 days old), when using
alcohol-blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is
unavoidable, follow recommended precautions.
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL ® or an equivalent.
• Drain tank and run the engine dry before storing unit.
