2. Safety Precautions and Warnings

To prevent personal injury or damage to vehicles and the scan tool, carefully read this user's manual and observe the following safety precautions whenever working on a vehicle:

• Always perform automotive testing in a safe environment.
• Do not attempt to operate or observe the tool while driving a vehicle. Operating or observing the tool will cause driver distraction and could lead to a fatal accident.
• Wear safety eye protection that meets ANSI standards.
• Keep clothing, hair, hands, tools, and test equipment away from all moving or hot engine parts.
• Operate the vehicle in a well-ventilated work area. Exhaust gases are poisonous.
• Place blocks in front of the drive wheels and never leave the vehicle unattended while running tests.
• Use extreme caution when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltages when the engine is running.
• Put the transmission in Park (P) for automatic transmissions or Neutral (N) for manual transmissions, and ensure the parking brake is engaged.
• Keep a fire extinguisher suitable for gasoline/chemical/electrical fires nearby.
• Do not connect or disconnect any test equipment while the ignition is ON or the engine is running.
• Keep the scan tool dry, clean, and free from oil, water, or grease. Use a mild detergent on a clean cloth to clean the outside of the scan tool when necessary.

The manufacturer is not responsible for any damage caused by unintentional or deliberate misuse of this product or tool.
