OPERATING INSTRUCTIONS
13
Each time the head is bumped, about 1 in.
(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.
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 posts
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.
