Genie Articulated Boom Lift S85

- Check the Track Tension and Fastener Torque, TRAX Models - S-40 and S-45 Models

Maintaining proper track tension and properly torqued fasteners is essential to good machine performance and service life; The machine will not operate properly with a track that is incorrectly tensioned. Continued use of a machine with incorrectly tensioned tracks may cause component damage

1. Thoroughly clean the track assembly of any dirt, rocks, clay, etc.

2. Chock the tracks at one end of the machine to prevent the machine from rolling

3. Center a lifting jack of ample capacity (20,000 Ibs / 10,000 kg) under the drive chassis between the tracks at the other end of the machine

4. Lift the machine until the tracks are off the ground and then place jack stands under the drive chassis for support

5. Visually inspect the section of track under the bogey wheels

Result: There should be less than 1 inch / 2.5 cm of gap between the bogey wheels and the inside surface of the track. Proceed to step 7

Result: There is 1 inch / 2.5 cm or more of gap between the bogey wheels and the inside surface of the track. Proceed to step 6

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

- 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 Emergency Power System (excludes ALC-600 and ALC-1000 Models)

1. 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

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

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

• Result: All boom functions operate

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

5 Turn the key switch to platform controls

6. At the platform controls, break the security tie and lift the emergency power switch cover (if equipped). 7. Press down on the foot switch and simultaneously hold the emergency power switch on and operate each boom function through a partial cycle

• Result: All boom functions operate

- 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;
