ADJUSTING THE TRIMMING LINE LENGTH
(For units with bump heads)
If the unit is equipped with a bump head, trimming line can be released from the cutting head without
stopping the engine. Before doing so, make sure the cutting head is loaded with line. Refer to the Line
Replacement Addendum.
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.
NOTE: Do not rest the cutting head on the ground while the unit is running.
Each time the bump knob is tapped, about 1 inch (25.4 mm) of trimming line is released.
NOTE: Always keep the trimming line fully extended. Line release becomes more dicult 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.
