5.2 Trimming Techniques
For best results, use a smooth, sweeping motion. Avoid forcing the blades through thick branches.

Figure 2: A user demonstrating proper two-handed grip and posture while trimming a hedge.
- Horizontal Trimming: Hold the hedge trimmer with the blade slightly angled downwards (about 10-15 degrees) and sweep across the top of the hedge. This angle helps to create a clean, even cut.
- Vertical Trimming: When trimming the sides of a hedge, start at the bottom and work upwards. This allows cut material to fall away, preventing it from getting caught in the blades.

- Cutting Thick Branches: The 18mm tooth spacing allows for cutting thicker branches. However, avoid forcing the tool. If a branch is too thick, use appropriate pruning shears.
- Avoid Obstructions: Be mindful of fences, walls, and other hard surfaces that could damage the blades.
