ASSEMBLY INSTRUCTIONS
INSTALL CUTTING ATTACHMENT SHIELD
WARNING:
To prevent serious personal injury, never operate the
unit without the cutting attachment shield in place.
Use the following instructions if the cutting attachment shield on the unit is not installed.
1. Place the cutting head shield onto the guard mount bracket, making sure to
align the holes on the shield with the ones in the guard mount bracket. (Fig. 1)
2. Take the 2 shield screws and screw each one into the shield until finger tight.
3. Using an appropriate screw driver, tighten the screws until the shield is firmly in
place. Make sure the screws are tightened equally so there is a balanced gap
between the bracket and the shield on each side.
INSTALLING AND ADJUSTING THE D-HANDLE
Installing the D-handle
1. Push the D-handle down onto the boom (Fig. 2), so that the bolt hole in the D-
handle is to the right.
2. Insert the bolt into the hole in the handle. Do not tighten the bolt completely
until after adjusting the D-handle.
Adjusting the D-handle
1. Make sure the bolt is loose enough for the D-handle to move along the boom.
2. While holding the unit in the operating position (Fig. 2), move the D-handle to the location that provides the best
grip. Place it a minimum of 6 inches (15.24 cm) from the end of the shaft grip.
3. Tighten the bolt until the D-handle is secure. (Fig. 2)
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
WARNING:
It has been proven that fuel containing greater than 15% ethanol will likely damage this
engine and void the warranty.
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 choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in the 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
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.
The bottle of 2-cycle oil that came with the unit contains a fuel additive which will
help inhibit corrosion and minimize the formation of gum deposits. It is
recommended to 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.
FUELING THE UNIT
WARNING:
Add fuel in a clean, level and well ventilated outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilled 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.
1. With the unit on a flat, level surface; remove the fuel cap.
2. Place the gas container's spout into the fill hole on the fuel tank 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.

WARNING:
position when pulling the starter rope (Fig. 5). To avoid serious injury, the
operator and unit must be in a stable position while starting.
1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel Mixing
Instructions.
NOTE:
There is no need to turn the unit on. The On/Off Control is in the ON ( I )
position at all times (Fig. 3).
2. Fully press and release the primer bulb 10 times, slowly. Some amount of fuel
should be visible in the primer bulb and fuel lines (Fig. 4). If fuel can not be seen in
the bulb, press and release the bulb as many times as it takes before fuel can see.
Starter Rope Grip
3. Place the blue choke lever in Position 1 (Fig. 4).
4. Crouch in the starting position (Fig. 5), squeeze the throttle control, and pull the
starter rope out with a controlled and steady motion 5 times.
NOTE:
The throttle control should be kept squeezed throughout the remainder
of these steps.
5. Place the blue choke lever in Position 2 (Fig. 4).
6. While squeezing the throttle control, pull the starter rope with a controlled and
steady motion 3 to 5 times.
7. Keep the throttle squeezed and allow the engine to warm up for 30 to 60 seconds.
8. Continue to squeeze the throttle control, move the blue choke lever in Position 3
(Fig. 4) and continue warming the engine for an additional 60 seconds. During this
time the unit may be used.
NOTE:

The Bump Head™ cutting head allows the release of trimming line without stopping the engine. To release more
Bracket
line, lightly tap the cutting head on the ground (Fig. 7) while operating the unit at high speed.
NOTE:
Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line
gets shorter.
Each time the head is bumped, about 1 inch (25.4 mm) of trimming line releases. A blade in the cutting head shield
will cut the line to the proper length if any excess line is released.

For best results, tap the bump knob on bare ground or hard soil. If attempting to release line in tall grass, the engine
may stall. Always keep the trimming line fully extended. Line release becomes more difficult when the cutting line
gets shorter.
D-Handle
NOTE:
Do not rest the Bump Head™ on the ground while the unit is running.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick, stalky weeds
• Forcing the line into objects such as walls or fence posts

TIPS FOR BEST TRIMMING RESULTS
Fig. 2
• Keep the cutting head parallel to the ground.
• Do not force the cutting head. Allow the tip of the line to do the cutting, especially along walls. Cutting with more
than the tip will reduce cutting efficiency and may overload the engine.
• Cut grass over 8 inches (200 mm) by working from top to bottom in small increments to avoid premature line
wear or engine drag.
• Cut from right to left whenever possible. Cutting to the left improves the unit's cutting efficiency. Clippings are
thrown away from the operator.
• Slowly move the unit into and out of the cutting area at the desired height. Move either in a forward-backward or
side-to-side motion. Cutting shorter lengths produces the best results.
• Trim only when grass and weeds are dry.
• The life of the cutting line is dependent upon:
Following the trimming techniques
What vegetation is being cut
Where vegetation is cut
For example, the line will wear faster when trimming against a foundation wall as
opposed to trimming around a tree.
DECORATIVE TRIMMING
Decorative trimming is accomplished by removing all vegetation around trees, posts, fences and more.
Rotate the whole unit so that the cutting head is at a 30° angle to the ground (Fig. 8).
