Torque ProcedureSeal-Lok™ fittings

1 Replace the O-ring. The O-ring must be replacedanytime the seal has been broken. The O-ringcannot be re-used if the fitting or hose end hasbeen tightened beyond finger tight.

Note: The O-rings used in the Parker Seal Lok™fittings and hose ends are custom-size O-rings.They are not standard SAE size O-rings. They areavailable in the O-ring field service kit (Genie partnumber 49612).

2 Lubricate the O-ring before installation.

3 Be sure that the face seal O-ring is seated andretained properly.

4 Position the tube and nut squarely on the faceseal end of the fitting and tighten the nut fingertight.

5 Tighten the nut or fitting to the appropriatetorque per given size as shown in the table.

6 Operate all machine functions and inspect thehoses and fittings and related components toconfirm that there are no leaks.

JIC 37° fittings

1 Align the tube flare (hex nut) against the nose ofthe fitting body (body hex fitting) and tighten thehex nut to the body hex fitting to hand-tight,approximately 30 in-lbs / 3.4 Nm.

2 Make a reference mark on one of the flats of thehex nut, and continue it on to the body hexfitting with a permanent ink marker. Refer toFigure 1.

4-1Level Sensor

Each machine is equipped with two types of levelsensors:

Tilt level sensorOne level sensor monitors the incline of theturntable after the outriggers are deployed and themachine is level. When this level sensor activates,an alarm will sound, making the operator aware of apotentially hazardous situation.

The tilt alarm sounds when the incline of thechassis exceeds 2.5° in any direction. The tilt levelsensor is located on the side of the machineopposite the ground controls.

Outrigger auto level systemWhen deploying the outriggers using the autolevelfunction, outrigger level sensors are used tomonitor the incline of the turntable and assist inleveling the machine.

In early production, two level sensors arecomponents of the outrigger auto level circuit. Laterin production, a single autolevel module was used.The outrigger level sensor(s) are located on theground controls side of the machine.

How to Install and Calibrate theTilt Level Sensor

Tip-over hazard. Failure to installor calibrate the level sensor asinstructed could result in themachine tipping over causingdeath or serious injury. Do notinstall or calibrate the level sensorother than specified in thisprocedure.

1 Perform this procedure with the machine on afirm, level surface that is free of obstructions.

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

3 Push and hold the yellow function enable button.Push and hold the auto level button.

Result: The outriggers will lower and adjust tolevel the machine and raise the wheels off theground. Use the bubble levels located on thechassis to confirm that the machine is level.

6-5Valve 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.

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.
