OIL AND FUEL INFORMATION
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
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:
DO NOT USE E85 FUEL IN THIS UNIT. It has been proven that fuel containing greater than 15% ethanol
will likely damage this engine and void the warranty.
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.
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:
Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit without the fuel cap securely in
place.
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.

INSTALL AND ADJUST THE D-HANDLE
Cover
1. Push the D-handle down onto the shaft housing (Fig. 1). The squared bolt hole in the handle should
be placed on the side the operator will be operating the unit from.
2. Insert the shoulder bolt into the squared hole in the handle and push through. On the opposite
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.
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. 10), 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 HEAD SHIELD
Use the following instructions if the cutting head shield
on your unit is not installed or if you ever need to re-
install it.
1. Place the cutting head 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. 2). The holes in the guard
mounting bracket and cutting head shield will line up.
2. From inside the cutting head shield, push the square
bolt through the hole until the threaded end protrudes
through the guard mounting bracket (Fig. 3).
3. Put the washer on the bolt, then screw the wing nut
onto the bolt and tighten.
