Hydraulic System
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.
A hydraulic system with an excessive increase in heat
or noise is a potential 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 internal component
damage.
The charts that follow contain information to assist in
troubleshooting. There may possibly be more than one
cause for a machine malfunction.
Refer to the Testing section of this Chapter for precau-
tions and specific test procedures.
