ADJUSTING TRIMMING LINE LENGTH
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. 23) while operating the trimmer at
high speed.
NOTE: Always keep the trimming line fully
extended. Line release becomes more difficult
as the cutting line becomes shorter.
Each time the head is bumped, about 1 inch
(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
WARNING:
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.
