Maintenance - Craftsman Weedwacker 316.790130 Operator's Manual

TO ADJUST THE TRIMMING LINE LENGTH
Your trimmer is equipped with a cutting attachment that
allows the operator to release more trimming line without
stopping the unit. To release additional line, lightly bump
the cutting attachment on the ground while
operating the trimmer at high speed (Fig. 12).
NOTE: Line release becomes more difficult as cutting
line becomes shorter. Always keep the trimming line
extended to its full cutting length.
Each time the head is bumped, about 1 inch (25.4 mm)
of line is released. A blade in the guard will cut the line to
the proper length if excess line is released.
For best results, bump the head on bare ground or hard
soil. If line release is attempted in tall grass, the motor
may overheat and fail.
WARNING:
Do not remove or alter the line
cutting blade assembly. Excessive line length
can cause unit to overheat and result in
serious personal injury.
DECORATIVE TRIMMING
Perform decorative trimming by removing all vegetation
around trees, posts, fences, etc.
Rotate the entire unit so that the cutting attachment is at
a 30° angle to the ground (Fig. 13).
