Genie Articulated Boom Lift Z-33/18

- Test the Primary Boom Angle Sensor - SX-105 XC, SX-125 XC, SX-135 XC, SX-150 and SX-180

A properly functioning primary boom angle sensor is essential to safe machine operation. The ECM at the ground controls (TCON) 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 must be tested before starting this procedure. Refer to Maintenance Procedures, 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

Note: Perform this procedure with the booms in the fully stowed position and the axles fully extended

- 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

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 the Hydraulic Filters

Note: There are four types of hydraulic filters: tank return filter, medium pressure filter, high pressure filter and drive motor case drain filter. The quantity and type of filter(s) may vary by model

Models with Filter Condition Indicator:

1. Start the engine from the ground controls

2. Set the engine idle to high rpm (rabbit symbol)

3. Visually inspect the filter condition indicator

• Result: The filter condition indicator is operating in the green area

• Result: The filter condition indicator is operating in the red area. This indicates that the hydraulic filter is being bypassed and the filter should be replaced. Refer to Maintenance Procedure, Replace the Hydraulic Filters

Models without Filter Condition Indicator:

- Check / clean the oil cooler and cooling fins - Deutz D2011 and D436 Models

- Replace Engine oil and filter

- Check/adjust Valve clearance - Test/add Engine coolant

- Replace Fuel filter / separator;
