Genie Articulated Boom Lift S-100

- Test the Turntable Level Sensor - Z-135/70, ZX-135/70, SX-105 XC, SX-125 XC, SX-135 XC, SX-150 and SX-180

A properly functioning level sensor (SCON) is essential to safe machine operation. The ECM at the ground controls (CON) monitors the position and angle of the machine using the signal from the level sensor. The level sensor signal is used to control the maximum working height of the primary and secondary booms

Note: A digital level will be required to perform this procedure

Note: A kit is available through Genie Product Support (Genie part number 58351). This kit includes a digital level with a magnetic base and cable harnesses

Note: A properly calibrated digital level is essential to proper machine calibration. Refer to the manufactures calibration information

Note: Use the following chart to identify the description of each LCD screen control button used in this procedure

Note: Perform this procedure with the booms in the fully stowed position and the axles fully extended

1. Place the machine on a firm surface that has a side slope greater than 2° (6.5 inches / 16.5 cm) but less than 5° (16 inches / 40.6 cm)

2. Place a digital level that has been calibrated to gravity on the X axis of the turntable

- Check for leaks Oil, fuel and coolant systems

- Replace engine oil and filter

- Clean/replace air cleaner element

- Check electrical wiring for chafing or damage

- Check the Turntable Rotation Bearing Bolts

Maintaining proper torque on the turntable bearing bolts is essential to safe machine operation

Improper bolt torque could result in an unsafe operating condition and component damage

Note: Access to the upper and lower turntable bearing bolts will vary depending on model

1. S Booms, Z-45 XC and Z-45/25 (J) IC, DC, Bi-Energy: Raise the (primary) boom and place a safety chock on the lift cylinder rod

Carefully lower the boom onto the lift cylinder safety chock OR support the boom assembly with a suitable lifting device

All other Z Booms: Raise the secondary boom and place a safety chock on the lift cylinder rods. Carefully lower the boom onto the lift cylinder safety chock OR support the boom assembly with a suitable lifting device

Crushing hazard. Keep hands away from the cylinder and all moving parts when lowering the boom

- Check the Generator Belts, Pulleys and Voltage - Bi-Energy Models

Bodily injury hazard. Do not inspect while the engine is running. Remove the key to secure from operation

Bodily injury hazard. Beware of hot engine components

Contact with hot engine components may cause severe burns

Note: Charging the batteries with the engine does not fully charge the batteries. Periodically, use the AC battery charger to fully charge the batteries

1. Be sure that all fasteners and cables on the generator are tight

2. Remove the engine flywheel cover mounting fasteners, then remove the cover

- Check the Drive Hub Oil Level and Fastener Torque

Failure to maintain proper drive hub oil levels may cause the machine to perform poorly and continued use may cause component damage

1. Drive the machine to rotate the hub until the plugs are located one on top and the other at 90 degrees

2. Remove the plug located at 90 degrees and check the oil level

Result: The oil level should be even with the bottom of the plug hole

3. If necessary, remove the top plug and add oil until the oil level is even with the bottom of the side plug hole. 4. Install the plug(s) into the drive hub

5. Check the torque of the drive hub mounting bolts. Refer to Specifications, Machine Torque Specifications

6. Repeat this procedure for each drive hub
