Genie Articulated Boom Lift Z45/25JBE

- Test the Platform Load Sense System - S-60 HC

Genie specifications require that this procedure be performed annually OR when the machine fails to lift the maximum rated load

Testing the platform overload system regularly is essential to safe machine operation. Continued use of an improperly operating platform overload system could result in the system not sensing an overloaded platform condition. Machine stability could be compromised resulting in the machine tipping over

Note: Be sure that no load sense system faults exist prior to performing this procedure

Note: On a properly functioning machine, the LEDs on both control modules, located next to the ground control box, should be off

1. Remove all weight, tools, accessories and equipment from the platform

Note: Failure to remove all weight, tools and accessories from the platform will result in an inaccurate test

2. 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

3. Start the engine from the ground controls

Warning: This procedure requires trained personnel with PPE!

Ensure the turntable level sensor and secondary boom angle sensor have been tested before starting this procedure.

A digital level will be required to perform this procedure.

Perform this procedure with the machine on a firm, level surface with the booms in the fully stowed position and the axles fully extended.

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 enter or previous button on the LCD screen until PRIMARY BOOM ANGLE TO GRAVITY DEGREES is displayed.

Place a digital level that has been calibrated to gravity on top of the primary boom.

Raise the primary boom while watching the display screen.

- Test the Ground Control Override

A properly functioning ground control override is essential to safe machine operation. The ground control override function is intended to allow ground personnel to operate the machine from the ground controls whether or not the Emergency Stop button on the platform controls is in the on or off position

This function is particularly useful if the operator at the platform controls cannot return the boom to the stowed position

1. Push in the platform red Emergency Stop button to the off position

2. Turn the key switch to ground controls

3. Pull out the red Emergency Stop button to the on position at the ground controls

4. From the ground controls, operate each boom function through a partial cycle

• Result: All boom functions should operate

5. From the platform, activate the foot switch and operate each boom function

Warning: This procedure requires trained personnel with PPE!

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

Enter the reading on the dial indicator

Start this procedure with the machine in the fully stowed position

Turn the key switch to platform control and pull out the red Emergency Stop button to the on position at both the ground and platform controls

Start the engine from the platform controls

Move the yellow bumper at the bottom of the platform 4 inches/10 cm in any direction

Activate each function control handle or toggle switch

Extend the primary boom approximately 3 ft / 1 m

Move the yellow bumper at the bottom of the platform 4 inches/10 cm in any direction

Activate each function control handle or toggle switch

Activate and hold the aircraft protection override switch
