Genie Articulated Boom Lift Z45/25J

- Test the Safety Envelope Limit Switches, Z-135/70, ZX-135/70, SX-105 XC, SX-125 XC, SX-135 XC, SX-150 and SX-180 Models

Testing the machine envelope safety limit switches is critical to safe machine operation. If the boom is allowed to operate when a safety switch is not functioning correctly, the machine stability could be compromised and may tip over

Note: Perform this procedure with the boom in the stowed position

Note: Perform this procedure with the axles extended

Note: Two people will be required to perform this procedure

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

Z-135/70 and ZX-135/70 Models:

Secondary Boom #1 Retracted Safety Limit Switch, LSS1RS

1. Working at the platform end of the turntable, support and secure the lower turntable riser end cover to a suitable lifting device

Inspect the Tires, Wheels and Lug Nut Torque

Grease the Turntable Rotation Bearing and Rotate Gear

Check the Turntable Rotation Bearing Bolts

Sign off on the boom lift maintenance

Test the Platform Self-leveling

Lower the boom to the stowed position at the ground controls

Activate function enable and adjust the platform to a level position

Raise and lower the primary boom through a full cycle

Enter the platform level in degrees

The platform remained level at all times to within +/-5 degrees

Sign off on the platform self-leveling test

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

CAUTION! 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

All fasteners and cables on the generator are tight

Engine flywheel cover mounting fasteners removed

Pulley mounting fasteners are tight and pulleys show no signs of damage or unusual wear

Engine pulley and the generator pulley are aligned within specification using a straightedge

Pulley alignment, maximum offset: 0.0625 inch / 1.58 mm

Inspect the generator belts for

Visual inspection of the hydraulic oil color: should be a clear, light-honey colored

Visual inspection of the hydraulic oil appearance: should be clear and not cloudy or visibly distorts the view through the sight glass or container

Visual inspection of the hydraulic oil contamination: should contain no particles, foreign objects, or other contamination

Smell test of the hydraulic oil: can smell 'hot' but not 'burnt'

Feel test of the hydraulic oil: should feel viscous and free of any rough feel due to particles

If the hydraulic oil fails any of the above inspections, the hydraulic oil must be tested by an oil distributor or replaced

Note: If the hydraulic oil was not replaced at or before 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

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