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

5. 

Low Hydraulic Fluid Level In Reservoir: 

 

Low  hydraulic  fluid  level  in  reservoir  can  be  caused  by  leaking  fittings,  hoses  or 
pipes. 

 

a.  Check all the fittings for leaks.  Tighten any loose fittings that are found (but do 

not over-tighten). 

b.  Replace defective fittings. 
c.  Check all tubing for leaks.  Repair or replace as necessary.
