SECTION 4: OIL AND FUEL INFORMATION
DANGER: OVERFILLING OIL CRANKCASE
MAY CAUSE SERIOUS PERSONAL INJURY!
The importance of checking and maintaining
the proper oil level in the crank case cannot
be overemphasized. Check oil before each
use and change as needed. See Changing
the Oil in the Maintenance and Repair
Instructions section.

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. 4).
NOTE: Save the bottle to measure the correct amount
for future oil changes. See Changing the Oil in
the Maintenance and Repair Instructions
section.
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. 4).
2. Place the unit on a flat level surface.
3. Remove the oil plug / dipstick from the crankcase
(Fig. 5).

Oil Fill
NOTE: Never add oil to the fuel or fuel tank.
5. Wipe up any oil that may have spilled and reinstall
the oil fill plug/dipstick.

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 ruin the fuel or 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
• Drain tank and run the engine dry before storing unit.
Using Fuel Additives
The use of fuel additives, such as STA-BIL
or an equivalent, will inhibit corrosion and minimize the
formation of gum deposits. Using a fuel additive can keep
fuel from forming harmful deposits in the carburetor for up
to six (6) months. 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
gas tank.
