OPERATING INSTRUCTIONS
HOLDING THE TRIMMER
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 right 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 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. 10) 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
• 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.
• Cut from right to left whenever
WARNING:
Always wear
eye, hearing, foot and body
protection to reduce the risk of
injury when operating this unit.
CAUTION:
Do not remove
or alter the line cutting blade
assembly. Excessive line
length will make the unit
overheat. This may lead to
serious personal injury or
damage to the unit.
