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 i
ncrease 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 detailed information to
assist in troubleshooting. There may possibly be more
than one cause for a machine malfunction. All causes
should be checked in the order in which they are listed
on the charts.
Refer to the Testing section of this Chapter for precau-
t
ions and specific test procedures.
NOTE: In this troubleshooting guide, cartridge valves or
ports in the control valve block are referred to by the
labels used on the valve block and shown on the sche-
matics, i.e. R1, S1, VS1 (Fig. 10, 11, 12).
