MULTIMETER-DIGITAL 9U7330 - Caterpillar

When using an external electrical source to start your engine: turn the START switch off, remove the key, and turn off all electrical accessories before attaching cables.When using jumper cables always connect the POSITIVE (+) cable to the POSITIVE (+) terminal of the battery connected to the starter solenoid. Connect the NEGATIVE (-) cable from the external source to the starter NEGATIVE (-) terminal. If not equipped with a starter NEGATIVE terminal, connect to the engine block.Do not reverse the battery cables. The alternator can be damaged. Attach the ground cable last and remove first.
1. Connect one end of the cable to the POSITIVE (+) terminal of the battery being started. Connect the other end to the POSITIVE (+) terminal of the power source.2. Connect one of the other cable to the NEGATIVE (-) terminal of the power source. Connect the other end to starter NEGATIVE (-) terminal or to the engine block. This prevents potential sparks from igniting combustible gases produced by some batteries.3. Start the engine.4. After the engine starts, disconnect the cable from the starter NEGATIVE (-) terminal or engine block. Disconnect the other end from the NEGATIVE (-) terminal of the power source.5. Disconnect the cable from the POSITIVE (+) terminal of the battery on the engine being started. Disconnect the cable from the POSITIVE (+) terminal of the power source.Air Starting
For good life of the air starting motor, the air supply must be free of dirt and water. A lubricator must be used with the starting system. Use non detergent 10W engine oil for temperatures that are greater than 0°C (32°F) or use air tool oil for lower temperatures.1. Open and close the drain valve on the bottom of the air tank to drain condensation and oil carryover.2. Check the air supply pressure. The air starting motor requires a minimum of 690 kPa (100 psi) air pressure to operate properly. The maximum air pressure must not exceed 1550 kPa (225 psi). The normal air pressure will be 758 to 965 kPa (110 to 140 psi).

Push the air valve (1) or the engine start button to crank the engine. Release the valve or button as soon as the engine starts.Cold Weather Starting Aids
Personal injury or death can result from using ether.Personal injury or property damage can result from alcohol or starting fluids. Alcohol or starting fluids are highly flammable and toxic and if improperly stored could result in injury or property damage.When using starting fluid, follow the manufacturer's instructions carefully. Use ether sparingly and spray it only while cranking the engine.Failure to follow these instructions could result in an explosion and/or fire and possible personal injury.
Excessive ether can cause piston and ring damage. Use ether for cold starting purposes only. Do not use excessive starting fluid during starting or after the engine is
