CUTTING TIPS

• Tilt the machine toward the area to be cut. Use the tip of
the cutting line to cut grass.
• Move the machine from right to left to prevent thrown
debris toward the operator.
• Do not cut in the dangerous area.
• Do not force the trimmer head into uncut grass.
• Wire and picket fences cause cutting line wear and
breakage. Stone and brick walls, curbs, and wood can
wear the cutting line quickly.
9.5 ADJUST THE LENGTH OF THE
CUTTING LINE
The machine has an auto-feed head. It will damage the
machine if you hit the head to try to advance the line.
If the cutting line does not automatically advance, it can be
tangled or empty.
