Abnormal aspects relating to the rotating equipment should be considered reason to shut down the fluid cooler until the problem can be located and corrected. Observe operation of the motor, coupling (or drive shaft), Geareducer, if equipped and fan. Become familiar with the normal operating temperature of the motor(s), as well as the sight and sound of all components as a whole.
If equipped, check Geareducer oil level. Shut down the unit and allow 5 minutes for the oil level to stabilize. Add oil if required. Check for Geareducer oil leaks. Check the Geareducer as well as any optional oil lines to external oil dipstick/sight glass.
