2. Safety Information

For your own safety and the safety of others, and to prevent damage to the device and vehicles upon which it is used, it is important that the safety instructions presented throughout this manual be read and understood by all persons operating or coming into contact with the device.

2.1 Safety Messages

Safety messages are provided to help prevent personal injury and equipment damage. All safety messages are introduced by a signal word indicating the hazard level.

DANGER:

• Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury to the operator or to bystanders.
• When an engine is operating, keep the service area WELL VENTILATED or attach a building exhaust removal system to the engine exhaust system. Engines produce carbon monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to serious personal injury or loss of life.
• It is not advised to use headphones at a high volume. Listening at high volumes for long periods of time may result in loss of hearing.

WARNING:

• Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury to the operator or to bystanders.

2.2 Safety Instructions

• Always perform automotive testing in a safe environment.
• Wear safety eye protection that meets ANSI standards.
• Keep clothing, hair, hands, tools, test equipment, etc., away from all moving or hot engine parts.
• Operate the vehicle in a well-ventilated work area.
• Put the transmission in PARK (for automatic transmission) or NEUTRAL (for manual transmission) and make sure the parking brake is engaged.
• Put blocks in front of the drive wheels and never leave the vehicle unattended while testing.
• Be extra cautious when working around the ignition coil, distributor cap, ignition wires, and spark plugs. These components create hazardous voltages when the engine is running.
• Keep a fire extinguisher suitable for gasoline, chemical, and electrical fires nearby.
• Do not connect or disconnect any test equipment while the ignition is on or the engine is running.
• Keep the test equipment dry, clean, and free from oil, water, and grease. Use a mild detergent on a clean cloth to clean the outside of the equipment as necessary.
• Do not drive the vehicle and operate the test equipment at the same time. Any distraction may cause an accident.
• Refer to the service manual for the vehicle being serviced and adhere to all diagnostics procedures and precautions. Failure to do so may result in personal injury or damage to the test equipment.
• To avoid damaging the test equipment or generating false data, make sure the vehicle battery is fully charged and the connection to the vehicle DLC is clean and secure.
• Do not place the test equipment on the distributor of the vehicle. Strong electro-magnetic interference can damage the equipment.
