Risk of injury.
• This equipment should be operated by qualified person-
nel 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.
Operation of this equipment by anyone other than qualified
personnel may result in injury.
Risk of unexpected vehicle movement.
• Block drive wheels before performing a test with engine
running.
• 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, discon-
nect 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 disconnect-
ing 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 dam-
age.
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 equip-
ment 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.
