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

service procedure encountered does not jeopardize your personal safety.

iii
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
Wear safety glasses and protective clothing.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
Have plenty of fresh water and soap nearby incase battery acid contactsskin, clothing
or eyes.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flush eye with cold running water for at least ten minutes and
get medical attention immediately.
Use caution when working with metallic tools to prevent sparks or short circuits.
Remove any jewelry or watches before you start servicing the battery.
Keep hair, hands, and clothing as well as tester leads and cords away from moving
blades and belts.
