Things You Should Know
CAUTION: EXHAUST GAS
When performing any checks with the engine running in an enclosed space such as a
garage, ensure proper ventilation. Never inhale exhaust gases; they contain carbon
monoxide
—a colorless, odorless, extremely dangerous gas that can cause
unconsciousness or death.
CAUTION: PARKING BRAKE
To help avoid personal injury, always set the parking brake securely and block the drive
wheels before performing any checks or repairs on the vehicle.
CAUTION: SPARKS
The Tech2 uses parts that can produce arcs or sparks. When used in a garage
environment, the Tech2 must be located not less than 18 inches (460 mm) above the floor.
NOTICE:
•
DO NOT clasp battery clamps together when connected simultaneously to the
vehicle’s 12 volt cigarette lighter or power supply. Reverse polarity in the vehicle’s
cigarette lighter may be present. Damage could occur to the Tech2 or to the vehicle.
•
If power is applied to the Tech2 and the display remains blank, reverse polarity in the
cigarette lighter may be present. Damage to the Tech2 could occur. DO NOT connect
the DLC cable to the vehicle. Verify that the center contact of the vehicle’s cigarette
lighter has +12 volts and that the outer contact is grounded.
•
Turn off the power before inserting or removing the PCMCIA card. Continual removal
and reinsertion of this card is not recommended.
•
Align all cards and components carefully before inserting them into the Tech2
•
Do not place the Tech2 so that the tilt stand can make contact with the vehicle
battery terminal as this could short out the battery.
