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.
There are various procedures, techniques, tools, and parts for servicing
vehicles, as well as in the skill of the person doing the work. Because of the
vast number of test applications and variations in the products that can be
tested with this equipment, we cannot possibly anticipate or provide advice
or safety messages to cover every circumstance. It is the automotive
technician’s responsibility to be knowledgeable of the system being tested. It
is crucial to use proper service methods and test procedures. It is essential
to perform tests in an appropriate and acceptable manner that does not
endanger your safety, the safety of others in the work area, the device being
used, or the vehicle being tested.
Before using the device, always refer to and follow the safety messages and
applicable test procedures provided by the manufacturer of the vehicle or
equipment being tested. Use the device only as described in this manual.
Read, understand, and follow all safety messages and instructions in this
manual.
Safety Messages
Safety messages areprovided to help prevent personal injury and equipment
damage. All safety messages are introduced by a signal word indicating the
hazard level.
DANGER

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

iii
Safety Instructions
The safety messages herein cover situations Autel is aware of. Autel cannot
know, evaluate or advise you as to all of the possible hazards. You must be
certain that any condition or service procedure encountered does not
jeopardize your personal safety.
DANGER
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.
SAFETY WARNINGS
Always perform automotive testing in a safe environment.
Wear safety eye protection that meetsANSI 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, for exhaust gases are
poisonous.
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, free from oil, water or grease. Use a
mild detergent on a clean cloth to clean the outside of the equipment as
necessary.
Do not drivethe vehicle andoperate thetest equipment at thesame time.
Any distraction may cause an accident.

iv
Refer to the service manual for the vehicle being serviced and adhere to
all diagnostic 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.
