Genie Articulated Boom Lift S80

- Grease the Extendable Axles - S-100, S-105, S-120, S-125, S100HD and S-120HD

Manufacturer specifications require that this procedure be performed every 50 hours

Lubricating the front and rear axles helps to ensure the smooth operation of the axles over the lifetime of the product; Two fittings on each axle are provided to apply grease the top and bottom sliding wear pads

1. Locate the grease fittings on the extendable axles covers

2. Thoroughly pump grease into each grease fitting. When grease is pumped into each fitting, a hose directs this lubrication to the top or bottom wear pad

3. Cycle the extending axles in and out

Note: Genie recommends that the extending axles be cycled in and out at least once a week;

- Test Secondary Boom Angle Sensor - Z-135/70 and ZX-135/70

A properly functioning secondary boom angle sensor is essential to safe machine operation. The ECM at the ground controls (TCON) monitors the position and angle of the secondary boom using the signal from the secondary boom angle sensor

The secondary boom angle sensor signal is used to control the ramping of the secondary boom

Note:The turntable level sensor must be tested before starting this procedure. Refer to Maintenance Procedure, Test the Turntable Level Sensor

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

1. Turn the key switch to ground control and pull out the red Emergency Stop button to the on position at both ground and platform controls

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 degree to which the platform remained level

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

Sign off on the platform self-leveling test

- 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:

- 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
