WARNING:
proper oil level in the crank case; it is important and cannot be overemphasized. Check the oil before
each use and change it as needed. See Changing the Oil.
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
D-Handle
NOTE: This unit is shipped without oil. In order to avoid damage to the unit, put oil in
the crankcase before you attempt to start the unit.
Your unit is supplied with one 3.04 fluid oz. (90 ml) bottle of SAE 30 SF, SG, SH oil
Bottom
(Fig. 16).
Clamp
NOTE: Save the bottle of oil. It can be used to measure the correct amount during
future oil changes. See Changing the Oil.
1. Unscrew the top of the bottle of oil and remove the paper seal covering the
Fig. 1
opening. Replace the top. Next, cut the tip off the funnel spout (Fig. 16).
2. Tip unit so that the back of the engine is facing up in a vertical position.
3. Remove the oil fill plug from the crankcase (Fig. 18).
4. Pour the entire bottle of oil into the oil fill hole (Fig. 17).
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.
Check oil before each use and change as needed. Refer to Checking the Oil Level.
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance. Be sure to use fresh,
Fig. 3
clean, unleaded gasoline.
Screws (3)
NOTE: This is a four cycle engine. In order to avoid damage to the unit, do not mix
oil with gasoline.
Gearbox
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 or form acids when stored.
Use fresh fuel (less than 30 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:
Fig. 4
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit
USING FUEL ADDITIVES
WARNING:
Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.
WARNING:
