- 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".
