LINE HEAD USAGE

WARNING

1.Always wear eye protection such as safety goggles. Never lean over the rotating cutting head. Rocks or other debris could be thrown into eyes and face and cause serious personal injury.

2.Keep the debris guard attached in place at all times when the unit is operated.

TRIMMING GRASS AND WEEDS

Always remember that the TIP of the line does cutting. You will achieve better results by not crowding the line into the cutting area. Allow the unit to trim at its own pace.

1.Hold the unit so the head is off the ground and is tilted about 20 degrees toward the sweep direction. (OP6)

2.You can avoid thrown debris by sweeping from your right to the left.
