INSTALL CUTTING ATTACHMENT SHIELD
Use the following instructions if the cutting
attachment shield on the unit is not installed.
Use only the instructions that apply to the
type of shaft and shield that the unit is
equipped with.
1. Place the cutting attachment shield onto the
shaft housing. Be sure the guard mounting
bracket slides into the slot on the edge of the
cutting shield. Rotate the shield into place,
counterclockwise (Fig. 1). The holes in the guard mounting bracket and cutting attachment shield will line up.
2. From inside the cutting attachment shield, push the square bolt through the hole until the threaded
end protrudes through the guard mounting bracket (Fig. 2).
3. Put the washer on the bolt, then screw the wing nut onto the bolt and tighten.
ADJUSTING THE D-HANDLE
1. Loosen the bolt on the handle just enough to move it (Fig. 3).
2. While holding the unit in the operating position (Fig. 14), move the
D-handle to the location that provides the best grip.
3. Tighten the bolt until the D-handle is secure. (Fig. 3)

WARNING:
Overfilling oil crankcase may cause serious personal injury. Check and maintain the
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
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 (Fig. 7).
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
opening. Replace the top. Next, cut the tip off the funnel spout (Fig. 7).
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. 8).
4. Pour the entire bottle of oil into the oil fill hole (Fig. 9).
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, 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 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:

WARNING:
Add fuel in a clean, well ventilated outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilt fuel. Do not start the engine until fuel vapors dissipate.
WARNING:
Gasoline is extremely flammable. Ignited vapors may explode. Always stop the engine
and allow it to cool before filling the fuel tank. Do not smoke while filling the tank. Keep sparks and open
flames at a distance from the area.

• 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
The use of fuel additives, such as STA-BIL® Gas Stabilizer 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.
FUELING THE UNIT
1. Remove the fuel cap (Fig. 10).
2. Place the gas container’s spout into the fill hole on the fuel tank (Fig. 10) and fill the tank.
NOTE:
Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.
NOTE:
Dispose of the old gasoline in accordance with federal, state and local regulations.
