hot surfaces, air intakes, belts and live electrical components. Do not leave any disassembled
components on the motor or in its vicinity; do not leave any tools or other parts not belonging to the
system in the same room or near the set.
- Always wear protective gloves when working.
- Always wear a hard hat, protective glasses and safety footwear in the work area.
- Always wear ear protection to avoid damage to your hearing, especially when spending long periods
near the running machine.
- Never wear loose-fitting clothes, rings and/or necklaces when working near motors or moving parts.
- Risk of fire. Never leave flammable liquids or rags soaked with flammable liquids near the set or near
