Genie Articulated Boom Lift S-125

Perform this procedure more often if dusty conditions exist. Maintaining the steer axle wheel bearings is essential for safe machine operation and service life.

Loosen the wheel lug nuts. Do not remove them

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

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

Remove the lug nuts. Remove the tire and wheel assembly

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

Remove the dust cap from the hub. Remove the cotter pin from the castle nut

Tighten the castle nut to specification, to seat the bearings

Loosen the castle nut and re-tighten to specification

Testing the machine safety envelope is critical to safe machine operation.

Start the engine from the ground controls

Raise the boom to approximately 60°

Extend the boom to more than 80 feet / 24.4 m

Push in the red Emergency Stop button to the off position

Plug in the LSB2RS test jumper between the lower limit switch and the function manifold

Pull out the red Emergency Stop button to the on position and start the engine

Disconnect the 68° proximity switch LSB14A0 and install a wire jumper between pin 3 and pin 4 of the Deutsch connector

Activate the function enable/high RPM button and extend the boom to 101 feet / 30.8 m

- 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

- 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:
