OPERATING INSTRUCTIONS
HOLDING THE TRIMMER
Before operating the unit, stand in the operating
position (Fig. 26). 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 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
WARNING: Always wear eye,
hearing, foot and body protection to
reduce the risk of injury when
operating this unit.

USING THE CUTTING BLADE
Before operating the unit with the cutting blade, stand in the operating
position (Fig. 29). Refer to Holding the Trimmer.
Cutting Blade Operating Tips
To establish a rhythmic cutting procedure:
• Plant feet firmly, comfortably apart.
• Bring the engine to full throttle before
entering the material to be cut. At full throttle
the 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:
• Cut at full throttle
• Swing the unit into material to be cut from your left to your right (Fig. 30)
• Avoid the material just cut as you make the return swing
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.
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.

ADJUSTING TRIMMING LINE LENGTH
The cutting head allows you to release trimming
line without stopping the engine. To release
more line, lightly tap the cutting attachment on
the ground (Fig. 27) 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 cutting head on bare ground or hard soil. If line
release is attempted in tall grass, the engine may stall.
NOTE: Do not rest the cutting 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.
• 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
• 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. 28).
