Genie Articulated Boom Lift Z-45/25J 4WD

- Check for leaks, damage or deterioration Oil, coolant, fuel, exhaust and vacuum hoses

- Check for chafing or damage Electrical wiring

- Clean/Adjust/Replace Spark plugs

- Tighten/Replace Loose or missing fasteners

- 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

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

- 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

- Test the Platform Self-leveling

1. At the ground controls, lower the boom to the stowed position

2. Activate function enable and adjust the platform to a level position

3. Raise and lower the primary boom through a full cycle

Result: The platform should remain level at all times to within +/-5 degrees;
