Genie Articulated Boom Lift S-105

- Test the Operator Protection Alarm (if equipped)

Testing the operator protection alarm (OPA) is important for proper operation

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

2. Start the engine from the platform controls

3. Do not activate the foot switch. Press down on the operator protection activation strip

• Result: There is no audible alarm or flashing beacon. The engine does not shut down (engine models)

4. Activate the foot switch. Press down on the operator protection activation bar for longer than 0.4 seconds and release

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

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

The primary boom angle sensor signal is used to control the ramping of the primary boom, limiting the speed of the primary boom to 2.3 feet / 0.7 meters per second

Note:The turntable level sensor and secondary boom angle sensor must be tested before starting this procedure. Refer to Maintenance Procedures, Test the Turntable Level Sensor and Test the Secondary Boom Angle 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

Note: Perform this procedure with the machine on a firm, level surface with the booms in the fully stowed position and the axles fully extended

- Test the Drive Speed - Stowed Position

Note: Perform this procedure with the machine on a firm, level surface that is free of obstructions

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

1. Create start and finish lines by marking two lines on the ground 40 feet / 12.2 m apart

2. Choose a point on the machine (i.e., contact patch of a tire) as a visual reference for use when crossing the start and finish lines

3. Bring the machine to top drive speed before reaching the start line. Begin timing when your reference point on the machine crosses the start line

4. Continue at full speed and note the time when the machine reference point crosses the finish line. Refer to Specifications, Drive Speed Specifications

- Test the Drive Speed - Raised or Extended Position

1. Create start and finish lines by marking two lines on the ground 40 feet / 12.2 m apart

- Test the Ground Control Override

A properly functioning ground control override is essential to safe machine operation. The ground control override function is intended to allow ground personnel to operate the machine from the ground controls whether or not the Emergency Stop button on the platform controls is in the on or off position

This function is particularly useful if the operator at the platform controls cannot return the boom to the stowed position

1. Push in the platform red Emergency Stop button to the off position

2. Turn the key switch to ground controls

3. Pull out the red Emergency Stop button to the on position at the ground controls

4. From the ground controls, operate each boom function through a partial cycle

• Result: All boom functions should operate

5. From the platform, activate the foot switch and operate each boom function

Drive hub specifications require that this procedure be performed after the first 50 hours of operation

After the initial oil replacement, specifications require that this procedure be performed every 1000 hours

Replacing the drive hub oil is essential for good machine performance and service life. Failure to replace the drive hub oil may cause the machine to perform poorly and continued use may cause component damage

1. Select the drive hub to be serviced. Drive the machine until one of the two plugs is at the lowest point

2. Remove the plugs and drain the oil into a suitable container

3. Drive the machine until one of the two plugs is at the highest point

4. Drive hubs with 2 plugs: Fill the hub until the oil level is even with the bottom of the lowest plug hole. Refer to Specifications, Hydraulic Specifications
