4. System Overheating:
System overheating may be caused by re-circulation of hot air through oil cooler,
dirty or obstructed oil cooler fins, restricted hydraulic fluid flow, excessive generator
load, restricted airflow, previously overheated (old) fluid, non-functional fan, or
improperly adjusted pump.
a. Check the oil cooler fins for debris or damage. Clean and/or replace cooler.
b. Verify that the generator load is not excessive.
c. Verify that there is proper ventilation.
d. Verify that the DC fan motor is operating properly.
e. Verify that warm air from the fan outlet is not being re-circulated through the
cooler.
f. Check the hydraulic fluid to see if it is black or darkened. This indicates
overheating or aging. Drain and flush the system.
g. Fill with new, clean hydraulic fluid.
h. Adjust pump, if necessary, only after contacting Smart Power
