1. Operator Personal Protection

1. Wear safety goggles, noise‑reducing earmuffs, protective gloves, non‑slip safety shoes and well‑fitted work clothes. Tie up long hair. Do not wear scarves, bracelets or other hanging accessories to avoid entanglement by rotating parts.

2. Minors are prohibited from operating this machine. Do not operate if you are drunk, under medication or physically fatigued.

2. Pre‑operation Inspection

1. Check the whole machine before use. Ensure correct fuel‑mix ratio. Inspect fuel tube for cracks and leakage.

2. Make sure harness and handles are firmly connected. Check blades and trimmer head for cracks, damage and looseness. Tighten all fasteners.

3. Never start or operate the machine with defects or damaged parts.

3. Fuel Refueling Safety

1. Refuel only in well‑ventilated outdoor areas. Refuel after the engine is fully cooled down.

2. No smoking while refueling. Keep away from open fire and sparks. Do not overfill the fuel tank. Wipe off spilled fuel before startup.

4. Work Site Preparation

1. Remove stones, metal wires, glass, branches and other hard debris from working area to prevent flying‑object injury caused by high‑speed rotating cutting parts.

2. Keep bystanders and pets outside the working zone.

5. Operation Specifications

1. Start the machine on flat ground. Stand firmly during operation.

2. Keep hands away from rotating cutting head. Never point cutting end at people or livestock.

3. If grass tangles the head, release throttle and shut down engine. Clean only after the cutting head stops completely. Do not clear tangles while machine is running.

4. Stop the engine immediately in case of heavy vibration, abnormal noise, power loss, overheating or smoke. Do not resume work until faults are solved.

6. Maintenance & Parts Replacement

1. Always power off and confirm cutting head has fully stopped before replacing blades, trimmer line or removing tangled grass.

2. Blades are extremely sharp. Wear hand protection during replacement to avoid cuts.

7. Working Environment & Storage

1. Do not operate in rainy, foggy or slippery conditions. Do not run engine in poorly‑ventilated enclosed space to avoid exhaust gas poisoning. Take breaks in hot weather to prevent heatstroke.

2. Let machine cool before storage. Drain fuel for long‑term storage and clean the unit. Store in dry, ventilated place out of children’s reach. Avoid direct sunlight and rain.
