OIL AND FUEL INFORMATION
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.

OPERATING INSTRUCTIONS
HOLDING THE TRIMMER
WARNING: Always wear eye, hearing, foot and body protection to
reduce the risk of injury when operating this unit.
Before operating the unit, stand in the operating position (Fig. 23). Check for the following:
• The operator is wearing eye protection and proper clothing
• With a slightly-bent right arm, the operator's right hand is holding the shaft grip
• The operator's left arm is straight, the left hand holding the assist handle
• The unit is at waist level
• The cutting attachment is parallel to the ground and easily contacts the grass without the need to bend over
ADJUSTING TRIMMING LINE LENGTH
WARNING:
Do not remove or alter the line cutting blade assembly. Excessive line length will make
the clutch overheat. This may lead to serious personal injury or damage to the unit.
The Bump Head™ cutting attachment allows you to release trimming line without stopping the engine. To release
more line, lightly tap the cutting attachment on the ground (Fig. 24) while operating the trimmer at high speed.
NOTE:
Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line
becomes shorter.
Each time the head is bumped, about 1 inch (25.4 mm) of trimming line is released. A blade in the cutting attachment
shield will cut the line to the proper length if excess line is released.
For best results, tap the Bump Head™ on bare ground or hard soil. If line release is attempted in tall grass, the engine
may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line
becomes 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
• For best trimming results, operate unit at full throttle.
• Keep the cutting attachment parallel to the ground.
• Do not force the cutting attachment. 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.
• Cutting from left to right improves the unit's cutting efficiency. Clippings are thrown away from the operator.
• Slowly move the trimmer 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 your cutting line is dependent upon proper adherence of explained
trimming techniques, what vegetation is cut, and 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 attachment is at a 30° angle to the ground (Fig. 25).
USING THE CUTTING BLADE
WARNING:
Always wear eye, hearing, foot, body protection and the shoulder strap to reduce the risk
of injury when operating this unit.
WARNING:
Do not use the cutting blade for edging or as an edger. Severe personal injury to yourself
or others can result.
Before operating the unit with the cutting blade, stand in the operating position (Fig. 23). Refer to Holding the Trimmer.

Cutting Blade Operating Tips
Gas Can Spout
To establish a rhythmic cutting procedure:
• Plant feet firmly, comfortably apart.
Fuel Cap
Fuel Tank
• Bring the engine to full throttle before entering the material to be cut. At full throttle the
Fig. 19
blade has maximum cutting power and is less likely to bind, stall or cause blade thrust
(which can result in serious personal injury to the operator or others).
• Cut while swinging the upper part of your body from left to right.
• Always release the throttle trigger and allow the engine to return to idle speed
when not cutting.
• When you are finished, always unsnap the unit from the harness before taking off
the harness.
• Swing the unit in the opposite direction as the blade spins, which increases the cutting action.
• After the return swing, move forward to the next area to be cut plant your feet again.
• The cutting blade is designed with a second cutting edge. You can use it by removing the blade, turning it upside
down, and reinstalling it.
To reduce the chance of material wrapping around the blade, follow these steps:
ON (I)
OFF (O)
• Cut at full throttle
• Swing the unit into material to be cut from your left to your right (Fig. 26)
• Avoid the material just cut as you make the return swing

LINE INSTALLATION
This section covers both SplitLine® and standard
single line installation.
Always use original equipment manufacturer 0.105 in.
(2.67 mm) replacement line. Other types of line may
make the engine overheat or fail.
There are two methods to replace the trimming line:
• Wind the inner reel with new line
• Install a prewound inner reel
Winding the Existing Inner Reel

6. Take approximately 18 feet (6 m) of new
trimming line, loop it into two equal lengths.
Insert each end of the line through one of the
two holes in the inner reel (Fig. 30). Pull the line
through the inner reel so that the loop is as
small as possible.
7. Wind the lines in tight even layers, onto the reel
(Fig. 31). Wind the line in the direction indicated
on the inner reel. Place your index finger
between the two lines to stop the lines from
overlapping. Do not overlap the ends of the
line. Proceed to step 11.

reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool.
7. Hold the inner reel in place and install the bump knob by turning counterclockwise. Tighten securely.
OPERATING INSTRUCTIONS
WARNING:
Blade thrust may occur when the spinning blade contacts an object that it does not
immediately cut. Blade thrust can be violent enough to cause the unit and/or operator to be propelled in any
direction, and possibly lose control of the unit. Blade thrust can occur without warning if the blade snags,
stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut.
WARNING:
The blade continues to spin after the engine is turned off. The coasting blade can
seriously cut you if accidentally touched.
WARNING:
Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break
off while in use. This can result in severe personal injury to yourself or others. Replace the blade.
WARNING:
Do not clear away any cut material with the engine running or blade turning. To avoid
serious personal injury, turn off the engine. Allow the blade to stop before removing materials wrapped
around the blade shaft.
