Risk of injury.

• This equipment should be operated by qualified

personnel only.

• Use this equipment only as described in this manual. Use

only the manufacturer’s recommended attachments.

• Do not operate equipment with a damaged cord or if the

equipment has been dropped or damaged, until it has

been examined by a qualified service representative.

personnel may result in injury.
Risk of unexpected vehicle movement.

• Block drive wheels before performing a test with engine

• Unless instructed otherwise, set parking brake and put

gear selector in neutral for standard transmissions or park

for automatic transmissions.

• If vehicle has an automatic parking brake release,

disconnect release mechanism for testing and reconnect

when testing is completed.

• Do not leave a running engine unattended.

A moving vehicle can cause injury.
Risk of equipment or circuit damage.

• Unless specifically directed by the manufacturer, make

sure the ignition is OFF before connecting or

disconnecting connectors or any vehicle electrical

terminals.

• Do not create a short between battery terminals with a

jumper wire or tools.

Improper equipment use can cause equipment or circuit

damage.
Misdiagnosis may lead to incorrect or improper repair and/or

adjustment.

Do not rely on erratic, questionable, or obviously erroneous

test information or results. If test information or results are

erratic, questionable, or obviously erroneous, make sure

that all connections and data entry information are correct

and that the test procedure was performed correctly. If test

information or results are still suspicious, do not use them

for diagnosis.

Improper repair and/or adjustment may cause vehicle or

equipment damage or unsafe operation.
Some vehicles are equipped with air bags. You must follow

vehicle service manual’s warnings when working around the

air bag components or wiring. If the service manual’s instruc-

tions are not followed, the air bag may open up unexpectedly,

resulting in personal injury. Note that the air bag can still open

up several minutes after the ignition key is off (or even if the

vehicle battery is disconnected) because of a special energy

reserve module.
