泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 位于发动机下方机架的左侧。 | |
当发动机起动开关转到起动位置时，Caterpillar 监控系统使泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 通电。 泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 随后循环工作，直到泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 已运行 6 秒为止。

预润滑功能启动时的监控系统显示。 | |
当泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 通电时，"P" 出现在 Caterpillar 监控系统显示屏上。 在泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 完成循环前，将始终显示 "P"。
在泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 完成循环后，发动机将起动。
注: 如果必须马上起动机器，可以超控发动机预润滑系统。 将钥匙转回 OFF 位置，以停止发动机预润滑。 将钥匙转回起动位置，以立即起动发动机。 如果在结束发动机预润滑后的 10 秒内未将钥匙转回起动位置，发动机预润滑将重新启动。 将在发动机 ECM 内记录预润滑超控事件。
如果以下一种情况存在，泵和马达（辅助转向、制动器分离、预润滑和快速换油 - quickevac） (1) 将不循环：
- 机油温度高于 50 °C (122 °F)。
- 发动机冷却液温度高于 50 °C (122 °F)。
- 发动机已经运行至少 2 分钟。
