- Replace the Hydraulic Filters

Perform this procedure more often if dusty conditions exist

Replacement of the hydraulic filters is essential for good machine performance and service life. A dirty or clogged filter may cause the machine to perform poorly and continued use may cause component damage. Extremely dirty conditions may require that the filter be replaced more often

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 filters) may vary by model

Bodily injury hazard. Beware of hot oil. Contact with hot oil may cause severe burns

Note: Perform this procedure with the engine off

Note: The return filter may be mounted in the top of the hydraulic tank (internally) or outside of the tank (externally)

Required maintenance procedures and additional engine information are available in the manufacturer's manuals. Refer to Specifications, Engine Operator and Maintenance Manuals

Perkins Models, every 4000 hours (p.171):

• Aftercooler core - clean/test

GM 3.0L, every 5000 hours (p.172):

• Cooling system coolant - replace

Perkins 1104D-44T, every 6000 hours, (p.172)

• Cooling system coolant extender (ELC) - add

Warning: This procedure applies to the following models: S-100, S-100HD, S-105, S-120, S-120HD, S-125, SX-105 XC, SX-125 XC, SX-135 XC, SX-150, SX-180, Z-80/60, Z-135/70 and Zx-135/70

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

Open the ground controls side turntable side cover

Pull out the red Emergency Stop button to the on position at both the ground and platform controls

At the ground controls, turn the bypass/recovery key switch to the run position

Turn the main key switch to ground control, start the engine and then turn the key switch to platform control

Check any machine function from the ground controls. The machine functions should not operate

Turn the main key switch to ground control

Check any machine function from the platform controls. The machine functions should not operate

- Test or Replace the Hydraulic Oil

Replacement or testing of the hydraulic oil is essential for good machine performance and service life. Dirty oil and a clogged suction strainer or hydraulic filters may cause the machine to perform poorly and continued use may cause component damage. Extremely dirty conditions may require oil changes to be performed more frequently

Note: Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific levels of contamination to verify that changing the oil is necessary. If the hydraulic oil is not replaced at the 2000 hour inspection, test the oil quarterly. Replace the oil when it fails the test

Note: When removing a hose assembly or fitting, the O-ring (if equipped) on the fitting and/or hose end must be replaced. All connections must be torqued to specification during installation. Refer to Specifications, Hydraulic Hose and Fitting Torque Specifications

Complete the hydraulic oil testing with an oil distributor

If the hydraulic oil passes testing at the 2000 hour maintenance interval, the oil must be tested every quarter by an oil distributor until the oil fails the test and is replaced

If the hydraulic oil fails testing at the 2000 hour maintenance interval, the oil must be replaced

After the oil has been replaced, continue the scheduled quarterly maintenance inspection

- Check the Drive Hub Oil Level and Fastener Torque

Failure to maintain proper drive hub oil levels may cause the machine to perform poorly and continued use may cause component damage

1. Drive the machine to rotate the hub until the plugs are located one on top and the other at 90 degrees

2. Remove the plug located at 90 degrees and check the oil level

Result: The oil level should be even with the bottom of the plug hole

3. If necessary, remove the top plug and add oil until the oil level is even with the bottom of the side plug hole. 4. Install the plug(s) into the drive hub

5. Check the torque of the drive hub mounting bolts. Refer to Specifications, Machine Torque Specifications

6. Repeat this procedure for each drive hub
