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 charts that follow contain information to assist in
troubleshooting. There may possibly be more than one
cause for a machine malfunction.
NOTE: The Workman vehicle hydraulic system is used
to operate the Topdresser 1800. When troubleshooting
a hydraulic problem on the Topdresser 1800, inspect the
Workman hydraulic system if both brush motor and con-
veyor motor are malfunctioning. If only one of the motors
appears to be malfunctioning, check that motor.
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 tow vehicle 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 com-
ponent damage.
