Troubleshooting
Factory trained mechanics, experienced operators, require a thorough understanding of the informa-
tion in this manual and accurate maintenance records are the best troubleshooting tools available.
Hydraulic o w diagrams are provided later in this section. These diagrams can be helpful in determin-
ing which parts are associated with a particular function. An electrical wiring diagram is included in
SERVICE AND REPAIR under ELECTRICAL SYSTEM. Problems in the hydraulic system may be found by
performing the pressure checks found in the CHECK-OUT PROCEDURES.
If at any point during the troubleshooting process you feel unquali ed for the task at hand, call your
dealer or a factory service representative. Continuing to perform troubleshooting or tuning methods
in an improper or incorrect manner can cause further problems aside from the original issue. A factory
representative can guide you through technical processes, while a certifi edCurbtender dealer is
capable of performing the task for you. Rely upon their expertise!
The inability of the hydraulic system to build pressure does not necessarily mean that the hydraulic
pump is bad. First check all system relief’s to ensure that they are not stuck in the open position. The
only accurate way to test the hydraulic pump is with the use of a hydraulic fl ow gauge. The
Quantum Compact pump is rated for 22 gpm @ 1300 RPM.
