Genie Articulated Boom Lift Z-45/22. Bi-Fuel

- Test the Drive Speed - Stowed Position

Note: Perform this procedure with the machine on a firm, level surface that is free of obstructions

Note: Perform this procedure with the machine in the stowed position

1. Create start and finish lines by marking two lines on the ground 40 feet / 12.2 m apart

2. Choose a point on the machine (i.e., contact patch of a tire) as a visual reference for use when crossing the start and finish lines

3. Bring the machine to top drive speed before reaching the start line. Begin timing when your reference point on the machine crosses the start line

4. Continue at full speed and note the time when the machine reference point crosses the finish line. Refer to Specifications, Drive Speed Specifications

- Test the Drive Speed - Raised or Extended Position

1. Create start and finish lines by marking two lines on the ground 40 feet / 12.2 m apart

Warning: Perform this procedure with the machine on a firm, level surface with the boom in the stowed position

Torque the turntable bearing bolts to specification

Raise the boom to full height using the ground controls

Place a dial indicator between the drive chassis and the turntable

Adjust the dial indicator needle to the 'zero' position

Lower the boom to a horizontal position and fully extend the boom

Note the reading on the dial indicator

Move the booms to the positions indicated in step 3

- 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:

Warning: Ensure the axles are fully extended before attempting this procedure

Is the wear pad measurement less than 0.437 inch/1.12 mm?

If a wear pad is not less than specification, shim as necessary to obtain minimum clearance and no drag

If any wear pads are replaced, refer to Repair Procedure in the appropriate Service and Repair Manual for your machine, Grease the Extendable Axles

Check for tight spots that may cause binding or scraping of the axle tubes

Sign off on the axle wear pads check

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
