ADJUSTING TRIMMING LINE LENGTH
The Bump Head™ cutting attachment allows you to
release trimming line without stopping the motor. To
release more line, lightly tap the cutting attachment on the
ground (Fig. 12) while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended.
Line release becomes more difficult when the
cutting line gets shorter.
