Genie Articulated Boom Lift S60-D-4WD

- Inspect the Electrical Contactor

Z-30N, 2-33, Z-34, Z-40 and Z-45 models:

1. Remove the drive chassis cover from the non-steer end of the machine and locate the electrical contactors)

2. Locate the electrical contactor mounted on the fuse bracket

Visually inspect the contact points of the contactor for the following items:

- 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

- Inspect for Turntable Bearing Wear

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

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

1. Grease the turntable bearing. Refer to Maintenance Procedure, Grease the Turntable Bearing and Rotate Gear

2. Torque the turntable bearing bolts to specification. Refer to Maintenance Procedure, Check the Turntable Rotation Bearing Bolts

3. S/SX-Booms: Using the ground controls, raise the boom to full height. Do not extend the boom

Z-Booms: Using the ground controls, raise the primary and secondary booms to full height. Do not extend the primary boom

Z-80/60, Z-135/70 and ZX-135/70: Using the ground controls, fully raise, but do not extend, the primary boom and jib. The secondary riser should remain in its stowed position

4. Place a dial indicator between the drive chassis and the turntable at a point that is directly under, or inline with, the boom and no more than 1 inch / 2.5 cm from the bearing

- Check oil, fuel, and coolant systems for leaks

- Clean/replace air cleaner element

- Replace engine oil and filter

- Test or Replace 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 or hydraulic filters 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 frequently

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. If the hydraulic oil is not replaced at the 2000 hour inspection, test the oil quarterly. Replace the oil when it fails the test

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

Complete the hydraulic oil testing with an oil distributor

If the hydraulic oil passes testing at the 2000 hour maintenance interval, the oil must be tested every quarter by an oil distributor until the oil fails the test and is replaced

If the hydraulic oil fails testing at the 2000 hour maintenance interval, the oil must be replaced

After the oil has been replaced, continue the scheduled quarterly maintenance inspection
