Safety Guidelines

This safety section contains information that must be followed to avoid damage to the Y.S.D.T. diagnostic tool or serious injury or death to the user. Please acknowledge this section – read it carefully.

• Thoroughly read and understand this manual before using the tool.
• Always make sure the diagnostic connections are clean, dry, and in good condition before connecting to a vehicle.
• Verify the vehicle battery is fully charged and in good condition before attempting to use the diagnostic tool. Low battery voltage WILL cause communication issues as well as produce invalid test results.

WARNING

Always make sure an approved exhaust ventilation system is in place and being used. Ensure the work area being used is well ventilated whenever running an engine. Carbon monoxide gas is extremely poisonous and can lead to serious injury or death.
WARNING
Always stay clear of moving parts and remove all loose clothing that can be caught in moving parts on the vehicle.
WARNING
Always wear approved safety glasses or goggles as necessary.
WARNING
Use extreme caution when working around batteries. Batteries can produce a highly explosive hydrogen gas that can cause the battery to explode without warning.
CAUTION
Always make sure diagnostic cables are free and clear of any belts, pulleys, or other moving parts on the vehicle being tested.
CAUTION
Be sure diagnostic cables DO NOT come in contact with hot engine components such as exhaust manifold or engine block.
CAUTION
Never allow diagnostic cables to lay near or on any ignition system components such as coils, spark plug wires, or solenoids as electrical interference may occur and may cause damage to the diagnostic tool and/or computer.
CAUTION
Never allow cables to lay on the floor near or in puddles of water. Water may leak into the diagnostic connectors and cause serious damage.
