Repeat this procedure until the engine is running smoothly.7. Once the engine is running smoothly, move the switch to the AUTO position.For starting below -18°C (0°F), use of additional cold weather starting aids is recommended. A coolant heater, fuel heater or extra battery capacity may be required.At temperatures below -23°C (-10°F), consult your Caterpillar dealer, or refer to the "Cold Weather Recommendations Operation and Maintenance Manual," SEBU5898, available from your Caterpillar dealer.Starting with an External Air Supply
Do not exceed 1035 kPa (150 psi), air pressure or damage to the air system can occur.

Batteries give off flammable fumes that can explode.Prevent sparks near the batteries. They could cause vapors to explode. Do not allow jump cable ends to contact each other or the machine.Do not smoke when checking battery electrolyte levels.Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.Always wear eye protection when starting a machine with jump cables.Improper jump procedures can cause an explosion resulting in personal injury.Always connect battery positive (+) to battery positive (+) and battery negative (-) to battery negative (-).Jump only with a battery source and with the same voltage as the stalled machine.Turn off all lights and accessories on the stalled machine. Otherwise, they will operate when the jump source is connected.
When starting from another machine, make sure the machines do not touch. This could prevent damage to engine bearings and electrical circuits.Turn on (close) the disconnect switch prior to the boost connection to prevent damage to electrical components on the stalled machine.This machine has a 24 volt starting system. Use only equal voltage for jump starting. Use of a welder or higher voltage will damage the electrical system.Severely discharged maintenance free batteries might not fully recharge by the alternator alone after jump starting.The batteries must be charged to the proper voltage by the battery charger.Many batteries thought to be unusable, are still rechargeable.Refer to Special Instructions, SEHS7633, Battery Test Procedure, available from your Caterpillar dealer, for complete testing and charging information.
