OIL AND FUEL INFORMATION
INSTALLING AND ADJUSTING THE D-HANDLE
1.
Push the D-handle down onto the shaft housing so that the squared bolt hole in the handle is to the right
(fig. 1).
2. Insert the shoulder bolt into the squared hole in the handle
and push through. On the left side of the handle, place the
washer on the bolt, then screw the wing nut onto the bolt. Do
not tighten until you make the handle adjustment (Fig. 1).
3. Rotate the D-handle to place the grip above the top of the
shaft housing. Place it a minimum of 6 inches (15.24 cm) from
the end of the shaft grip.
4. While holding the unit in the operating position (Fig. 11),
position the D-handle to the location that provides you the
best grip.
5. Tighten the wing nut until the D-handle is secure.
INSTALLING THE CUTTING ATTACHMENT SHIELD

OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit
not running properly. Be sure to use fresh, clean unleaded fuel.
Follow the instructions carefully for the proper fuel/oil mixture.
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. It forms acids when stored. When using
alcohol-blended fuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow recommended precautions:
•
Always use the fresh fuel mix explained in your operator's manual
• Always agitate the fuel mix before fueling the unit
• Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
The bottle of 2-cycle oil that came with your unit contains a fuel additive which will help inhibit corrosion
and minimize the formation of gum deposits. It is recommended that you use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for air-cooled engines along with a fuel additive, such as
STA-BIL® Gas Stabilizer or an equivalent. 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 fuel tank.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded gasoline in a separate fuel can. Use a
40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank. See the table below for specific gas and
oil mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one 3.2 oz. (95 ml.) bottle of 2-cycle oil
makes a 40:1 fuel/oil ratio.
NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations.
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.
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: Remove fuel cap slowly to avoid
injury from fuel spray. Never operate the unit
without the fuel cap securely in place.
CAUTION: For proper engine operation and
maximum reliability, pay strict attention to the oil
and fuel mixing instructions on the 2-cycle oil
container. Using improperly mixed fuel can
severely damage the engine.
