6.3 Trimming Techniques
- Hold the hedge trimmer with both hands, maintaining a firm grip.
- Keep the blade parallel to the hedge for an even cut.
- Work in a sweeping motion, moving the trimmer away from your body.
- Avoid cutting branches thicker than the maximum trim diameter (18mm).
- Do not force the tool through thick branches; this can damage the blade and motor.
7. Maintenance
7.1 Cleaning
