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 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.
WARNING

III
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury to the operator or to
bystanders.
Safety Instructions
The safety messages herein cover situations iCarsoft is aware of.
iCarsoft 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 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, 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.

IV
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 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 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 elector-magnetic interference can damage the
equipment.
