HOLDING THE TRIMMER
Before operating the unit, stand in the
operating position (Fig. 3). 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.
Adjusting Trimming Line Length
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. 4) while
operating the trimmer at high
speed.
NOTE: Always keep the trimming line fully extended. Line
release becomes more difficult as cutting line becomes
shorter.
Each time the head is bumped, about 1 inch (25.4 mm) of
trimming line releases. A blade in the cutting attachment 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 you attempt 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
• 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.

personal injury or damage to the unit.
