Genie Articulated Boom Lift S-120

- Test the Platform Overload System - All Models (if equipped), Except ALC1000, S-60HC, S-80XC, S-85XC and Z-45XC Models

Genie specifications require that this procedure be performed annually OR when the machine fails to lift the maximum rated load

Testing the platform overload system regularly is essential to safe machine operation. Continued use of an improperly operating platform overload system could result in the system not sensing an overloaded platform condition. Machine stability could be compromised resulting in the machine tipping over

This maintenance procedure applies to the following models: S-40, S-45, S-60, S-65, S-80, S-85, Z-45/25 (J), Z-51/30J, Z-30/20N (RJ), Z-34/22, Z-34/22 (N), Z-34/22 IC, Z-40/23N (RJ), Z-45/25 (J) DC, 2-45/25 (J) Bi-Energy, Z-60 DC/FE, Z-62/40 and models equipped with the 340 kg capacity option

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

1. Remove all weight, tools, accessories and equipment from the platform

Note: Failure to remove all weight, tools and accessories from the platform will result in an inaccurate test

2 Engine Models: Turn the key switch to ground control and pull out the red Emergency Stop button to the on position at both the ground and platform controls. Start the engine from the ground controls and level the platform. Do not turn the engine off

DC Models: Turn the key switch to ground controls and pull out the red Emergency Stop button to the on position at both the ground and platform controls. Level the platform

- 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

- 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

- Test the Alarm Package (if equipped)

Note: The alarms and beacon will operate with the engine running or not running

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

Z-80/60, S-80 XC, S-85 XC, S-100, S-105, S-120, S-125, S-100HD, S-120HD, SX-105 XC, SX-125 XC, SX-135 XC, SX-150, SX-180, Z-135/70 and ZX-135/70 Models:

Result: The alarm should sound twice. The flashing beacon should be on and flashing

Result: The flashing beacon should be on and flashing

2. Activate the boom down function, hold for a moment and then release it

- Inspect the Calibration Decal - ALC-1000 Models

This maintenance procedure applies to the following models: S-100, S-105, S-120, S-125, S-100HD, S-120HD, SX-105 XC, SX-125 XC, SX-135 XC, SX-150, SX-180, Z-80/60, Z-135/70 and ZX-135/70

1. Turn the key switch to the off position and push in the red Emergency Stop button to the off position at the ground controls

2. Open the turntable cover on the ground controls side of the machine

4. Verify the ground control panel is equipped with the required calibration decal

• Result: The control box is equipped with the required decal and is legible and in good condition

Result: The control box is not equipped with the required decal, or is illegible or in poor condition. Remove the machine from service until the decal is replaced

Note: Contact your authorized Genie distributor or Genie if a replacement is required;
