OPERATING INSTRUCTIONS
HOLDING THE UNIT
Before operating the unit, stand in the operating position (Fig. 9). Check for the
following:
• The operator is wearing eye protection and proper clothing
• With a slightly-bent right arm, the operator’s hand is holding the shaft grip
• The operator’s left arm is straight, the left hand holding the D-handle
• The unit is at waist level
• The cutting head is parallel to the ground and easily contacts the grass without
the need to bend over
ADJUSTING TRIMMING LINE LENGTH
The Bump Head™ cutting head allows the release of trimming line without stopping the engine. To release more line,
lightly tap the cutting head on the ground (Fig. 10) 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 a line release 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.
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
• 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.
WARNING:
Always wear eye, hearing, foot and body protection to reduce the risk of injury when operating
this unit.

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 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
The bottle of 2-cycle oil 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 fuel 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 for specific gas and oil mixing ratios.
NOTE:
One gallon (3.8 liters) of unleaded fuel 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.
