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.
The successful operation of the Pro Sweep 5200 de-
pends on the hydraulic system of the tow vehicle. When
troubleshooting a sweeper hydraulic problem, 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.
NOTE: When troubleshooting a hydraulic problem on
the Pro Sweep 5200, inspect tow vehicle hydraulic sys-
tem if both sweeper brush motor and lift cylinder are mal-
functioning. If one sweeper hydraulic component
appears to be malfunctioning, check that component.
