How to use

Before use, fit a compatible battery and ensure it is fully charged according to the battery manufacturer’s instructions. Hold the trimmer at a comfortable height and position the cutting head parallel to the ground for trimming or at a slight angle for edging. Move the trimmer in a steady sweeping motion across the grass, keeping the cutting line clear of hard objects. For edging, guide the trimmer along the border with controlled passes to achieve a uniform edge. Switch the tool off and remove the battery before performing any cleaning, line replacement or maintenance.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and closed footwear. Operate the trimmer on dry ground where possible and avoid contact with stones, metal or other debris that could damage the cutting line. For longer work periods, keep spare charged batteries available to maintain consistent performance.
