Genie Articulated Boom Lift S-65 HF

- 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

Perkins Models, every 4000 hours (p.171):

• Aftercooler core - clean/test

GM 3.0L, every 5000 hours (p.172):

• Cooling system coolant - replace

Perkins 1104D-44T, every 6000 hours, (p.172)

• Cooling system coolant extender (ELC) - add

- Inspect the Calibration Decal - ALC-1000 Models

This maintenance procedure applies to the following models: S-100, S-105, S-120, S-125, S-100HD, S-120HD, SX-105 XC, SX-125 XC, SX-135 XC, SX-150, SX-180, Z-80/60, Z-135/70 and ZX-135/70

1. Turn the key switch to the off position and push in the red Emergency Stop button to the off position at the ground controls

2. Open the turntable cover on the ground controls side of the machine

4. Verify the ground control panel is equipped with the required calibration decal

• Result: The control box is equipped with the required decal and is legible and in good condition

Result: The control box is not equipped with the required decal, or is illegible or in poor condition. Remove the machine from service until the decal is replaced

Note: Contact your authorized Genie distributor or Genie if a replacement is required;

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

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

The secondary boom angle sensor signal is used to control the ramping of the secondary boom

Note:The turntable level sensor must be tested before starting this procedure. Refer to Maintenance Procedure, 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

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

- Grease the Turntable Rotation Bearing and Rotate Gear

Perform this procedure more often if dusty conditions exist and when operating the machine in high temperature environments

Frequent application of lubrication to the turntable bearing and rotate gear is essential to good machine performance and service life. Continued use of an improperly greased bearing and gear will result in component damage

1. Locate the grease fitting for the turntable rotate bearing

2. Pump grease into the turntable rotation bearing. Rotate the turntable in increments of 4 to 5 inches / 10 to 13 cm at a time and repeat this step until the entire bearing has been greased

3. Models with Drive Gear: Apply grease to each tooth of the drive gear, located under the turntable

Models with Worm Drive Gear: Grease each tooth on the outside of the turntable rotation bearing

1. Locate the 2 grease fittings on top of the worm drive housing
