Important Safety Instructions
Risk of electric shock.
•Do not exceed voltage limits between inputs as indicated
in the “Specifications” on page3-2.
•Use extreme caution when working with circuits that have
greater than 60 volts DC or 24volts AC.

Electric shock can cause injury.

Risk of explosion.
•Wear safety goggles and protective clothing, user and
bystander. Everyday eyeglasses only have impact resis-
tant lenses, they are NOT safety glasses.
•Do not use this system in environments where explosive
vapor may collect, such as in below-ground pits, confined
areas, or areas that are less than 18 inches above the f loor.
•Use this equipment in locations with mechanical ventila-
tion providing at least four air changes per hour.
•Flammable fuel and vapors can ignite.
•Do not smoke, strike a match, or cause a spark in the vicin-
ity of the battery. Battery gases can ignite.
•Avoid making accidental connection between battery ter-
minals. Do not place uninsulated metal tools on the bat-
tery.
•When removing battery cables, remove ground cable first.
•Avoid sparks when connecting or disconnecting power
leads to battery.
•Be sure ignition is OFF, headlights and other accessories
are OFF and vehicle doors are closed before disconnect-
ing battery cables. This also helps prevent damage to
on-board computer systems.
•Always disconnect battery ground connections before
servicing electrical system components.

Explosion can cause injury.

Risk of poisoning.
•Use this equipment in locations with mechanical ventila-
tion providing at least four air changes per hour. Engine
exhaust contains odorless lethal gas.
•Route exhaust outside while testing with engine running.

Poisoning can result in death or serious injury.

Battery acid is a highly corrosive sulfuric acid.
•Wear safety goggles and protective gloves, user and
bystander. Everyday eyeglasses only have impact resis-
tant lenses, they are NOT safety glasses.
•Make sure someone can hear you or is close enough to
provide aid when working near a battery.
•Have plenty of fresh water and soap nearby. If battery acid
contacts skin, clothing, or eyes, flush exposed area with
soap and water for 10 minutes.
•Seek medical help.
•Do not touch eyes while working near battery.

Battery acid can burn eyes and skin.

Risk of fire.
•Wear safety goggles and protective clothing, user and
bystander. Everyday eyeglasses only have impact resis-
tant lenses, they are NOT safety glasses.
