OPERATION
ADJUSTING THE TRIMMING LINE LENGTH
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 the engine.
N
OTE: D
o 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.
