- Check the Track Tension and Fastener Torque

Maintaining proper track tension and properly torqued fasteners is essential to good machine performance and service life. The machine will not operate properly with a track that is incorrectly tensioned. Continued use of a machine with incorrectly tensioned tracks may cause component damage

1. Thoroughly clean the track assembly of any dirt, rocks, clay, etc.

2. Chock the tracks at one end of the machine to prevent the machine from rolling

3. Center a lifting jack of ample capacity (20,000 Ibs / 10,000 kg) under the drive chassis between the tracks at the other end of the machine

4. Lift the machine until the tracks are off the ground and then place jack stands under the drive chassis for support

5. Visually inspect the section of track under the bogey wheels

Result: There should be less than 1 inch / 2.5 cm of gap between the bogey wheels and the inside surface of the track. Proceed to step 12

Result: There is 1 inch / 2.5 cm or more of gap between the bogey wheels and the inside surface of the track. Proceed to step 6

- Check the Oscillate Directional Valve Linkage (if equipped)

1. Remove the drive chassis cover and the axle covers from the non-steer end of the drive chassis

2. Locate the oscillate directional valve inside of the non-steer axle and inspect the linkage for the following:

1) Lock nut is tight against yoke

2) Yoke clevis pins are installed

3) Cotter pins are installed through clevis pins

4) Linkage is properly attached to directional valve;

- Test the Primary Boom Angle Sensor - SX-105 XC, SX-125 XC, SX-135 XC, SX-150 and SX-180

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

The primary boom angle sensor signal is used to control the ramping of the primary boom, limiting the speed of the primary boom to 2.3 feet / 0.7 meters per second

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

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

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

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

The primary boom angle sensor signal is used to control the ramping of the primary boom, limiting the speed of the primary boom to 2.3 feet / 0.7 meters per second

Note:The turntable level sensor and secondary boom angle sensor must be tested before starting this procedure. Refer to Maintenance Procedures, Test the Turntable Level Sensor and Test the Secondary Boom Angle 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

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