1. Keep your clothing, hair, hands, tools, and test equipment at a safe distance from all operating or hot equipment to prevent accidents.
2. Take special care when working near the ignition coil, distributor cap, ignition wires, and spark plugs—these components can unleash dangerously high voltages when the engine is running.
3. Always have a fire extinguisher readily available when dealing with gasoline, chemicals, or electrical equipment to swiftly tackle any potential fire hazards.
4. Before beginning any tests, make sure to securely place the transmission in Park (for automatic vehicles) or Neutral (for manual vehicles) and engage the handbrake.
6. For your safety, avoid connecting or disconnecting any test equipment while the ignition is on or the engine is running. Your attention to these safety measures will ensure a secure and efficient testing experience.
