CUTTING TIPS

Figure 8.
• Tilt the machine towards 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 dangerous areas.
• 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.

CUTTING LINE

While you operate the machine, the cutting line gets
worn and shorter. You can adjust the length of the
cutting line.

cuts the excess length.

LINE CUT-OFF BLADE

Figure 10.
This trimmer is equipped with a line cut-off blade
on the guard. The line cut off blade continuously
trims the line to ensure a consistent and efficient cut
diameter. Advance line whenever you hear the engine
running faster than normal, or when trimming efficiency
diminishes. This will maintain best performance and
keep the line long enough to advance properly.
