If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.
When diagnosing faults in operation of the intensier, always check that the hydraulic power source is supplying the
correct hydraulic ow and pressure to the intensier as listed in the table. Use a ow meter known to be accurate.
Check the ow with the hydraulic uid temperature at least 80 °F/27 °C.
PROBLEM CAUSE SOLUTION
No output. Couplers or hoses blocked. Remove obstruction.
Input pressure and return line
hoses reversed at ports.
Be sure hoses are connected to the
proper ports.
No oil in reservoir. Fill reservoir to proper level.

assembly down.
Return intensier to upright position.
Oil mist from center of motor
housing assembly.
Rear drive shaft seal bad. Replace shaft seal located behind shaft
bushing in motor housing assembly.
Oil leaking from vent assembly. Oil reservoir over lled. Reduce oil level to the top of the high-
pressure pump as viewed through the
vent assembly port while the intensier
is in the horizontal position. (Reservoir
must have room for oil expansion.)
Defective shaft seal. Seal is located
in the oil seal plate between the
