Genie Articulated Boom Lift Z-45/25J RT

- Perform Maintenance – Jib Rotate Bearing - SX-150 and SX-180

Periodic inspection of jib bearing wear is essential to safe machine operation, good machine performance and service life. Continued use of a worn jib bearing could create an unsafe operating condition, resulting in death or serious injury and component damage

Note: Perform this procedure with the boom fully retracted and in the stowed position and with the machine on a firm, level surface

1. Check the Jib Rotator Fastener torque

2. Using a star pattern, confirm that each jib rotator outer mounting bolt is torqued in sequence to specification. Repeat the procedure for the inner mounting bolts

Jib boom rotate bearing bolts: 200 ft-Ibs/ 271 Nm

3. While rotating the jib, pump grease into each bearing lubricating grease fitting until fresh grease is visible at the outer seal

4. While rotating the jib, pump grease into the worm gear grease fitting until fresh grease is visible at one sealing lip or bearing cap

- Confirm the Proper Brake Configuration

1. Locate the drive hub disconnect cap

2. Check each drive hub disconnect cap to be sure it is in the engaged position

Collision hazard. Be sure that the machine is not in free-wheel or partial free-wheel configuration

Refer to maintenance procedure, Confirm the Proper Brake Configuration

Note: Select a test area that is firm, level and free of obstructions

1. Mark a test line on the ground for reference

Required maintenance procedures and additional engine information are available in the manufacturer's manuals. Refer to Specifications, Engine Operator and Maintenance Manuals

- Inspect Visually of the Hydraulic Oil

Replacement or testing of the hydraulic oil is essential for good machine performance and service life

Dirty oil and a clogged suction strainer may cause the machine to perform poorly and continued use may cause component damage

Extremely dirty conditions may require oil changes to be performed more often. For hydraulic oil specifications, Refer to Specifications, Hydraulic Specifications

Note: Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific levels of contamination to verify that changing the oil is necessary

Replace the oil when it fails the test Refer to Maintenance Procedure, Test or Replace the Hydraulic Oil

1. Collect a sample of hydraulic oil and place in a clear container. Visually inspect the hydraulic oil for the following:

1) Color: oil should be a clear, light-honey colored

2) Appearance, oil should be clear and not cloudy or visibly distorts the view through the sight glass or container

- Check the Free-wheel Configuration

Proper use of the free-wheel configuration is essential to safe machine operation. The free-wheel configuration is used primarily for towing. A machine configured to free-wheel without operator knowledge may cause death or serious injury and property damage

Models with 2 wheel steer will be referenced with Non-steer and steer wheels

Models with 4 wheel steer will be referenced with Circle-end and Square-end wheels

Collision hazard. Select a work site that is firm and level

Component damage hazard. If the machine must be towed, do not exceed 2 mph / 3.2 km/h

Non-steer or Circle-end wheels:
