Wear the right protection
Personal protective equipment is non-negotiable. Before you start:
- Eyes: certified safety glasses (EN 166) or a face shield.
- Ears: defenders (SNR 27 dB+) for petrol machines.
- Hands & body: gloves, sturdy boots and long trousers — cut-resistant for blade work.
See our safety gear guide for tested picks.
Keep people and pets clear
Keep everyone at least 15 metres away. Thrown stones and debris travel far and fast — the most common brush cutter injuries are to bystanders, not the operator.
Avoid blade kickback
Kickback is the biggest blade hazard — a spinning blade hitting something solid can throw the machine sideways. To avoid it:
- Cut with the correct part of the blade (typically the left/front segment).
- Keep the engine revs up — a slow blade grabs.
- Never cut above waist height, and keep a firm two-handed grip.
- Watch for hidden stones, wire and roots.
Work safely on slopes and around obstacles
- On slopes, cut across the incline, keep firm footing, and never overreach. See our slope guide.
- Use a harness for blade work and longer sessions.
- Stop the machine before crossing paths, refuelling or clearing the head.
- Never refuel a hot engine or work in wet conditions with a corded electric machine.
Before every use: check the guard is fitted, the head/blade is secure and undamaged, and the area is clear of people, pets and hidden debris.
