4. Operating
4.1 Starting and Stopping
The hedge trimmer is equipped with safety switches to prevent accidental starting.
- To Start: Ensure the battery is fully charged and properly installed. Press and hold the safety switch (usually on the front handle), then squeeze the trigger switch on the rear handle. The blades will begin to move.
- To Stop: Release the trigger switch. The blades will stop.
4.2 Cutting Techniques
The 58 cm double-action reinforced steel blade provides precise cuts. The 180° rotating handle allows for versatile cutting angles.
- Horizontal Cutting: For the top of hedges, hold the trimmer level and sweep across the top. The rotating handle can be set to 0° for this.
- Vertical Cutting: For the sides of hedges, hold the trimmer vertically. Adjust the handle to +90° or -90° for a more natural and less fatiguing grip.
- Sweeping Motion: Use a smooth, sweeping motion, allowing the blades to cut through the branches. Do not force the trimmer through thick material.
- Tip Protector: The blade features a tip protector to prevent scratches when working close to walls or the ground.
