Genie Genie Articulated Boom Lift ALC600 ALC600

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 the Safety Envelope and Circuits - Z-80/60

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

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

2. Start the engine from the ground controls

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

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

- Grease the Steer Axle Wheel Bearings, All 2WD Models (except S-60, S-65, Z-60 DC/FE and Z-62)

Perform this procedure more often if dusty conditions exist

Maintaining the steer axle wheel bearings is essential for safe machine operation and service life. Operating the machine with loose or worn wheel bearings may cause an unsafe operating condition and continued use may result in component damage. Extremely wet or dirty conditions or regular steam cleaning and pressure washing of the machine may require that this procedure be performed more often

1. Loosen the wheel lug nuts. Do not remove them

2. Block the non-steer wheels, then center a lifting jack under the steer axle

3. Raise the machine 6 inches / 15 cm and place blocks under the drive chassis for support

4. Remove the lug nuts. Remove the tire and wheel assembly

5. Check for wheel bearing wear by attempting to move the wheel hub side to side, then up and down

• Result: There should be no side to side or up and down movement

Required maintenance procedures and additional engine information are available in the manufacturer's manuals. Refer to Specifications, Engine Operator and Maintenance Manuals

- Grease the Platform Overload Mechanism (if equipped)

Perform this procedure more often if dusty conditions exist

Application of lubrication to the platform overload mechanism is essential to safe machine operation. Continued use of an improperly greased platform overload mechanism could result in the system not sensing an overloaded platform condition and will result in component damage

This maintenance procedure does not apply to the following models: S-80 XC, S-85 XC, SX-125 XC, SX-135 XC, Z-45 XC

1. Locate the grease fittings on each pivot pin of the platform overload assembly

2. Thoroughly pump grease into each grease fitting
