The platform controls, used to operate the machinefrom the platform or while standing on the ground,can also be used to tune the performance of themachine.

Moving the joystick or activating a button or toggleswitch sends a signal to the Electronic ControlModule (ECM). When the ECM is in the functionmode, the platform controls are used to operatethe various machine functions. When the ECM is inthe programming mode (PS is shown in thediagnostic display window), the platform controlsare used to adjust the function speed parameters.

The platform controls contains an electronic circuitboard, joystick, membrane decal, buttons, switchesand LEDs. Potentiometer-equipped joysticks canbe adjusted to maintain performance.

Hydraulic Pump

5-1Function Pump

The hydraulic pump is attached to the motor whichmakes up the Hydraulic Power Unit.

How to Test the Hydraulic PumpWhen removing a hose assemblyor fitting, the O-ring on the fittingand/or hose end must be replacedand then torqued to specificationduring installation. Refer toSection Two, Hydraulic Hose andFitting Torque Specifications.

1 Disconnect and plug the high pressurehydraulic hose from the hydraulic pump.

Bodily injury hazard. Sprayinghydraulic oil can penetrate andburn skin. Loosen hydraulicconnections very slowly to allowthe oil pressure to dissipategradually. Do not allow oil to squirtor spray.

2 Connect a 0 to 5000 psi / 0 to 350 bar pressuregauge to the high pressure port on the pump.

3 Turn the key switch to ground control and pullout the red Emergency Stop button to the onposition at both the ground and platformcontrols.

4 Activate the platform up function from theground controls.

Result: If the pressure gauge reads3200 psi / 221 bar, immediately stop. The pumpis good.

Result: If pressure fails to reach3200 psi / 221 bar, the pump is bad and willneed to be serviced or replaced.

Component damage hazard.There is no relief valve in thehydraulic pump and the pump canbe damaged if the pressure isallowed to exceed3200 psi / 221 bar. When testingthe pump, activate the pump inone second intervals until3200 psi / 221 bar is confirmed.Do not over-pressurize the pump.

5 Remove the pressure gauge and reconnect thehydraulic hose.

Bodily injury hazard. Sprayinghydraulic oil can penetrate andburn skin. Loosen hydraulicconnections very slowly to allowthe oil pressure to dissipategradually. Do not allow oil to squirtor spray.

How to Test a Coil DiodeGenie incorporates spike suppressing diodes in allof its coils. Properly functioning coil diodes protectthe electrical circuit by suppressing voltage spikes.Voltage spikes naturally occur within a functioncircuit following the interruption of electrical currentto a coil. Faulty diodes can fail to protect theelectrical system, resulting in a tripped circuitbreaker or component damage.

Electrocution hazard. Contact withelectrically charged circuits couldresult in death or serious injury.Remove all rings, watches andother jewelry.

1 Test the coil for resistance. See 6-4 How toTest a Coil.

6-4Valve Coils

How to Test a CoilA properly functioning coil provides anelectromotive force which operates the solenoidvalve. Critical to normal operation is continuitywithin the coil that provides this force field.

Electrocution hazard. Contact withelectrically charged circuits couldresult in death or serious injury.Remove all rings, watches andother jewelry.

1 Tag and disconnect the wire harness from thecoil to be tested.

2 Test the coil resistance.

Result: The resistance should be withinspecification, plus or minus 30%.

Result: If the resistance is not withinspecification, plus or minus 30%, replace thecoil.
