Trimming Instructions:

  • Working Position: Maintain proper footing and balance. Hold the unit firmly in both hands, with one hand on the switch handle and one on the bail handle.
  • Trimming New Growth: Use a wide, sweeping motion, feeding the blade teeth through the twigs. A slight downward tilt of the blade in the direction of motion provides the best cutting.
  • Leveling Hedges: Stretch a piece of string along the length of the hedge as a guide.
  • Side Trimming: Begin at the bottom and sweep up.

Maintenance

The cutting blades are made of high-quality hardened steel and do not require resharpening under normal use. If you accidentally hit a wire fence, stones, or other hard objects, inspect the blade for damage. If the blade is bent or teeth are damaged, have it repaired by an authorized service center. Clean the unit with mild soap and a damp cloth after removing the battery. Never immerse the unit in liquid. Apply a film of light machine oil to the blades after cleaning to prevent rust.

Safety

Always wear eye protection, non-skid safety shoes, and hearing protection. Keep hands away from blades. Do not use the trimmer in wet conditions. Check the hedge for foreign objects like wire fences before each use.
