ADJUSTING THE TRIMMING LINE LENGTH (BUMP HEAD)
This unit is equipped with a bump head. Trimming line can be
released from the cutting head without stopping the engine.
To release more line, lightly tap the bump knob on the ground (Fig. 16)
while operating the unit at high speed. For best results, tap the bump
knob on bare ground or hard soil. Attempting to release line in tall
grass may stall th
e engine.
N
OTE: Do not rest the cutting head on the ground while the unit is
running.
Each time the bump knob is tapped, about 1.5 inches (38 mm) of
trimming line is released.
NOTE: Always keep the trimming line fully extended. Line release
becomes more difficult when the cutting line gets shorter.
A blade in the cutting head shield will cut the line to the proper
length if any excess line is released.
WARNING:
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.

lowering the cutting head onto the grass.
• Cut with the tip of the trimming line.
• Cut in small increments. Move slowly. Do not force the unit.
• D
o not trim wet grass or weeds.
• When Using the Aero-Flex® Head: To improve performance and
maximize the life of the line blades, operate the unit at the
recommended speed when performing particular tasks:

• Decorative Trimming (against fences or other hard objects) -
Operate the unit at lower speeds.
• Edging - Operate the unit at lower speeds.

• Forcing the line / line blades into objects such as walls or
fence posts
