Troubleshooting
The cause of an improperly functioning hydraulic sys-
tem is best diagnosed with the use of proper testing
equipment and a thorough understanding of the com-
plete hydraulic system.
The chart below contains information to assist in trou-
bleshooting. There may possibly be more than one
cause for a machine malfunction.
The successful operation of the ProCore Processor de-
pends on the hydraulic system of the tow vehicle. When
troubleshooting a ProCore Processor hydraulic prob-
lem, make sure that the tow vehicle hydraulic system is
evaluated as well.
A hydraulic system with an excessive increase in heat
or noise has a potential for failure. Should either of these
conditions be noticed, immediately stop the machine,
turn off the engine, locate the cause of the trouble and
correct it before allowing the machine to be used again.
Continued use of an improperly functioning hydraulic
system could lead to extensive hydraulic component
damage.
