Also , be sure to ease into heavy growth to prevent overwhelming Do not trim on slopes when the ground is slippery . Trim the machine . across the face of a slope , not up and down . Slow down and exercise caution when changing direction on slopes . Grass and most other materials are most efficiently trimmed when dry . But the unit will do a fine Trim When Wet or Dry job even with damp or wet materials . When conditions are moist or damp , be sure to clean debris off the machine regularly to keep cutting efficiency high . And watch your footing !
