Important
Read, understand and obey the safety rules and operating instructions in the appropriate Operator's Manual on your machine before attempting any procedure.
This manual provides troubleshooting and repair procedures for qualified service professionals.
Basic mechanical, hydraulic and electrical skills are required to perform most procedures. However, several procedures require specialized skills, tools, lifting equipment and a suitable workshop. In these instances, we strongly recommend that maintenance and repair be performed at an authorized Genie dealer service center.

Torque Procedure

Seal-Lok™ fittings
1 Replace the O-ring. The O-ring must be
replaced anytime the seal has been broken. The O-ring cannot be re-used if the fitting or hose end has been tightened beyond finger tight.
Note: The O-ring in Parker Seal Lok™ fittings and hose end are custom-size O-rings. They are not standard size O-rings. T he y are avai lable in the O-ring field service kit (Genie part number 49612).
2 Lubricate the O-ring before installation. 3 Be sure the O-ring face seal is seated and
retained properly.
4 Position the tube and nut squarely on the face
seal end of the fitting, and tighten the nut finger tight.
5 Tighten the nut or fitting to the appropriate
torque. Refer to the appropriate torque chart in this section.
6 Operate all machine functions and inspect the
hose, fittings and related components to confirm there are no leaks.
JIC 37° fittings
1 Align the tube flare (hex nut) against the nose
of the fitting body (body hex fitting) and tighten the hex nut to the body hex fitting to hand tight, approximately 30 in-lbs / 3.4 Nm.
2 Using a permanent ink marker, make a
reference mark on one the flats of the hex nut and continue the mark onto the body of the hex fitting. Refer to Illustration 1.

3 Working clockwise on the body hex fitting,
make a second mark with a permanent ink marker to indicate the proper tightening position. Refer to Illustration 2.
Note: Use the JIC 37° Fitting table in this section to determine the correct number of flats, for the proper tightening position.
Note: The marks indicate the correct tightening positions have been determined. Use the second mark on the body hex fitting to properly tighten the joint after it has been loosened.

Platform Controls

Platform Controls

The platform controls contains two printed circuit boards:
The LED circuit board is mounted to the underside of the control box lid which contains the LEDs. The LED circuit board sends the input from the operator to the platform controls circuit board (PCON). The circuit board (PCON) sends the data to the turntable control box (TCON) for processing.
The platform controls ECM circuit board communicates with the turntable controls. The joystick controllers at the platform controls utilize Hall Effect technology and require no adjustment. The operating parameters of the joysticks are stored in memory at the turntable controls. If a joystick controller error occurs or if a joystick is replaced, it will need to be calibrated before that particular machine function will operate. Refer to Repair Procedure, How to Calibrate a Joystick Controller.
Each joystick controller should operate smoothly and provide proportional speed control over its entire range of motion.

How to Calibrate a Joystick
The joystick controllers on this machine utilize digital Hall Effect technology for proportional control. If a joystick controller is disconnected or replaced, it must be calibrated before that particular machine function will operate.
Note: The joystick must be calibrated before the threshold, max-out or ramping can be set.
Note: After each joystick is calibrated, check the display at the ground control box. There should be no calibration faults shown on the display. If calibration faults exist, repeat procedure for that joystick controlled function.
Note: Perform this procedure with the engine off. Note: Use the following chart to identify the
description of each LCD screen control button used in this procedure.

Crushing hazard. The platform leveling cylinder may fall if not properly suppor removed from the machine.

Platform Comp onents

2-1 Platform Leveling Cylinder

The platform leveling cylinder keeps the platform level through the entire range of boom motion. The platform is maintained level to the turntable. To accomplish this, the ECM at the ground controls compares the difference in readings between the platform angle sensor and the turntable level sensor, which then sends a signal to the platform controls to open or close the appropriate platform level proportional valve on the platform manifold to maintain a level platform. The platform leveling cylinder is equipped with counterbalance valves to prevent movement in the event of a hydraulic line failure.
How to Remove the Platform Leveling Cylinder
Note: When removing a hose assembly or fitting, the O-ring (if equipped) on the fitting and/or hose end must be replaced. All connections must be torqued to specification during installation. Refer to Specifications, Hydraulic Hose and Fitting Torque Specifications.
1 Extend the jib boom until the platform leveling
cylinder barrel-end pivot pin is accessible.
4 Place a block under the platform leveling
cylinder for support. 5 Remove the external snap rings from the
barrel-end pivot pin. Use a soft metal drift to
remove the barrel-end pivot pin. 6 Support the rod end of the platform level
cylinder. 7 Remove the pin retaining fasteners from the
platform leveling cylinder rod-end pivot pin.
Use a soft metal drift to remove the barrel-end

Component damage hazard. Mark the platform mounting weldment and the rotator flange before removing the platform mounting weldment. The platform mounting weldment must be replaced in the exact same position on the rotator flange as it was before removal. If a new rotator is installed or the rotator is disassembled, proper alignment can be achieved by rotating the rotator all the way to the left and then installing the platform mounting weldment all the way in the left position.
Component damage hazard. The platform angle sensor is a very sensitive instrument. It can be damaged internally if is dropped or sustains any physical shock, even if the damage is not visible.

4-8 Primary Boom Angle Sensor

The primary boom angle sensor is used to limit the angle of the primary boom relative to the angle of the secondary boom and gravity.
How to Replace the Primary Boom Angle Sensor
Note: Perform this procedure with the machine on a firm, level surface with the boom in the stowed position.
1 Remove the retaining fasteners from the boom
end cover at the pivot end of the primary boom. Remove the cover from the machine.
2 Locate the primary boom angle sensor inside
the primary boom at the boom pivot pin.
3 Disconnect the electrical connector from the
sensor.
4 Remove the angle sensor mounting bracket
retaining fasteners.
7 Install the new angle sensor onto the mounting
bracket. 8 Install one spring, removed in step 5, into the
hex-shaped hole in the angle sensor. Install
the other spring into the hex-shaped hole in the
center of the boom pivot pin. 9 Insert the hex-shaped key into the angle
sensor. 10 Align the side of the sensor with flat area of the
boom pivot pin as shown below while holding
the bracket away from key insertion.
5 Remove the angle sensor and bracket
assembly. Do not lose the two springs or the hex-shaped key.
6 Remove the sensor retaining fasteners from
the mounting bracket. Remove the angle sensor.
Note: Note the sensor orientation on the bracket during removal so the new sensor will be installed in the same position.

Refer to Repair Procedure, How to Calibrate
the Primary Boom Angle Sensor.
The primary boom maximum angle is gradually reduced as the downhill slope (positi ve degre e Y axis) is increased. A flat level surface of 0° allows the primary boom maximum operational angle to reach 68°. On a 5° downhill slope the primary boom maximum operational angle is reduced to 43°.
