------ WARNING! ------

Personal injury can result from rotating and moving parts. Stay clear of all rotating and moving parts.

Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified.

The machine must be parked on a level surface and the engine stopped.

Attach a "Do Not Operate" or similar warning tag to the start switch and controls before servicing, repairing, or making adjustments to the machine.


------ WARNING! ------

Personal injury or death can result from sudden machine movement.

Sudden movement of the machine can cause injury to persons on or near the machine.

To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.


------ WARNING! ------

Personal injury can result from hydraulic oil pressure and hot oil.

Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.

Make sure all of the attachments have been lowered, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.



NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, "AVSpare Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in AVSpare machines.

Dispose of all fluids according to local regulations and mandates.

    The Axle Pump is Shown From Left Side.

  14. Disconnect electrical connector (13) for the axle interlock from the axle pump.

  15. Lower the cab but do not install cover plates (6) and (8). Refer to Disassembly and Assembly, KENR6004, "Cab - Tilt".

  16. Move engine start switch (4) to the START position. Release the switch when the engine starts.

  17. Operate the engine at low idle for few minutes. Move throttle switch (3) to the HIGH IDLE position.

  18. Monitor hydraulic oil temperature with Tool (F). Operate the machine until the oil temperature reaches 43 ± 5.6 °C (110 ± 10 °F).

  19. Move throttle switch (3) to the LOW IDLE position.


    Illustration 11g01414291

  20. Move shift switch (14) to the HIGH SPEED position.

  21. Move parking brake switch (2) to the OFF position.

  22. Move the propulsion lever to the FORWARD range. Monitor pressure at forward pressure tap (12). Check the case drain flow when the pressure in the forward circuit is 10300 kPa (1500 psi). The flow should be 8.5 to 14.4 L/min (2.2 to 3.8 US gpm).

    Note: If 10300 kPa (1500 psi) cannot be reached, move the throttle switch to the HIGH IDLE position and recheck.

  23. Move the propulsion lever to the REVERSE range. Monitor pressure at reverse pressure tap (11). Check the case drain flow when the pressure in the reverse circuit is 10300 kPa (1500 psi). The flow should be a maximum of 8.5 to 14.4 L/min (2.2 to 3.8 US gpm).

  24. Move propulsion lever (1) to the NEUTRAL position.

  25. Move parking brake switch (2) to the ON position.

  26. Move engine start switch (4) to the OFF position.

  27. Raise the cab. Refer to Disassembly and Assembly, KENR6004, "Cab - Tilt".

  28. Reconnect electrical connector (13) for the axle interlock to the axle pump.

  29. Remove both sets of Tool (C) from the drum pump.

  30. Remove Tool (A) from the drum motor and reconnect case drain line (10).

  31. Remove Tool (D) and Tool (E). Reconnect brake supply line (9).
