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. 17) 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.
Fig. 17
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
