NOTICE

Do not crank the engine for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking again. Turbocharger (if equipped) damage can result, if the engine rpm is not kept low until the engine oil light/gauge verifies the oil pressure is sufficient.

Starting Below 0 °C (32°F)

If equipped with an air inlet heater (AIH) for cold weather starting, do not use aerosal types of starting aids such as ether. Such use could result in an explosion and personal injury.

While you are still operating the switch, turn the engine start switch key to the START position in order to start the engine. When the engine starts, hold down the starting aid switch for a few seconds more and then release the starting aid switch. If the engine does not run smoothly, press and hold down the starting aid switch again until the engine is running smoothly.
Allow the engine to warm up for several minutes. The actual time depends on the outside temperature. Use the latter part of this time to help warm up the hydraulic oil by operating the joystick control in order to raise the boom and lower the boom.

For starting below −18°C (0°F), the use of additional cold weather starting aids is recommended. Any of the following may be required.

A coolant heater
A fuel heater
An oil heater
An extra capacity battery

Before you operate the machine in temperatures below −23°C (−10°F), consult your Caterpillar dealer or see Operation and Maintenance Manual, SEBU5898, "Cold Weather Recommendations".
