Genie Articulated Boom Lift SX-125 XC

Warning: Maintaining the axle wear pads in good condition is essential to safe machine operation.

Start the engine from the platform controls and extend the axles

Is any wear pad less than specification?

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

Extend and retract the axles through the entire range of motion to check for tight spots that may cause binding or scraping of the axle tubes

Note: Always maintain squareness between the outer and inner axle tubes

Extendable axle wear pad Wear pad specifications : Minimum 0.4375 inch / 11.11 mm

A properly functioning level sensor (SCON) is essential to safe machine operation. The ECM at the ground controls (CON) monitors the position and angle of the machine using the signal from the level sensor. The level sensor signal is used to control the maximum working height of the primary and secondary booms

A digital level will be required to perform this procedure

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

A properly calibrated digital level is essential to proper machine calibration. Refer to the manufactures calibration information

Use the following chart to identify the description of each LCD screen control button used in this procedure

Perform this procedure with the booms in the fully stowed position and the axles fully extended

Place the machine on a firm surface that has a side slope greater than 2° (6.5 inches / 16.5 cm) but less than 5° (16 inches / 40.6 cm)

Place a digital level that has been calibrated to gravity on the X axis of the turntable

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

Inspect the Tires, Wheels and Lug Nut Torque

Grease the Turntable Rotation Bearing and Rotate Gear

Check the Turntable Rotation Bearing Bolts

Warning: This procedure requires trained personnel with PPE!

Track assembly cleaned of any dirt, rocks, clay, etc.

Tracks chocked at one end of the machine to prevent rolling

Lifting jack of ample capacity (20,000 Ibs / 10,000 kg) centered under the drive chassis

Machine lifted until the tracks are off the ground and jack stands placed under the drive chassis for support

Visual inspection of the section of track under the bogey wheels performed

Grease plug on the track tension cylinder located and loosened

Grease zerk fitting on the other side of the track tension cylinder located

Grease pumped into the grease zerk fitting of the tension cylinder until grease, free from air, comes out of the grease plug

Drive chassis cover and axle covers removed from the non-steer end of the drive chassis

Oscillate directional valve located inside of the non-steer axle

Cotter pins are installed through clevis pins

Linkage is properly attached to directional valve
