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 operating.
CAUTION: 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.
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
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. 7). Check for the following:
• The operator is wearing eye protection and proper
clothing.
• The right arm is slightly bent, and the hand is holding
the shaft grip.
• The left arm is straight, and the hand is holding the
handle.
• The unit is below waist level.
• The cutting attachment is parallel to the ground and
easily contacts the vegitation to be cut without the
operator having 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. 9) while operating the trimmer at high
speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult as cutting
