Genie Articulated Boom Lift Z-20N RJ

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

For limit switch and angle sensor information, Refer to appropriate Service and Repair Manual for your machine

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

Secondary Boom #1 Angle Safety Limit Switch, LSS2AS

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

Start the engine from the ground controls

Press the (plus)(minus) buttons on the LCD screen to activate status mode

Press the enter or previous button on the LCD screen until secondary boom length is displayed

Fully raise the secondary boom and extend the secondary boom approximately 2 feet / 61 cm

Inspect Visually of the Hydraulic Oil

Is the hydraulic oil a clear, light-honey color?

Is the hydraulic oil clear and not cloudy or visibly distorting the view through the sight glass or container?

Does the hydraulic oil contain no particles, foreign objects, or other contamination?

Does the hydraulic oil smell 'hot' but not 'burnt'?

Does the hydraulic oil feel viscous and free of any rough feel due to particles when rubbed between fingers?

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.

Check for leaks Oil, fuel and coolant systems

Clean/replace air cleaner element

Check electrical wiring for chafing or damage

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

At the ground controls, break the security tie and lift the emergency power switch cover (if equipped)

Simultaneously hold the emergency power switch on and operate each boom function through a partial cycle

Close the emergency power switch cover and secure the cover with a security tie (if equipped)

Turn the key switch to platform controls

At the platform controls, break the security tie and lift the emergency power switch cover (if equipped)

Press down on the foot switch and simultaneously hold the emergency power switch on and operate each boom function through a partial cycle

Close the emergency power switch cover and secure the cover with a security tie (if equipped)

Sign off on the emergency power system test

- 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
