Axis-Lubrication Reservoir Assembly- Replacement

1

Label the output grease hoses from the used axis-lubrication reservoir assembly so they can be put back in the same location when you are finished replacing the assembly.

Disconnect the input air hose and output grease hoses from the used axis-lubrication reservoir.

Remove the used axis-lubrication reservoir assembly from the cabinet.

Disconnect the pressure switch cable from the assembly.

Remove the air input fitting and the grease manifold fro the used axis-lubrication reservoir assembly.

2

Remove and discard the used 1/4" OD tube (same location as a new hose [2] shown in image) from the grease manifold [1].

Install the air input fitting [5] into the new axis-lubrication reservoir assembly [3]. Orient the top of the air input fitting parallel to the two screw bosses [4] on the new axis-lubrication reservoir [3]. 

Look at the bottom tip of the hose [5]. Verify:

  • The tip must be cut at 45 degrees.
  • It must clear the filter screen by approximately 1/16" (2mm).
  • If it is necessary to shorten the hose, cut it at the top.
    • Leave enough hose to make a god connection with the grease manifold [1].
    • Do not kink the hose.

Do not pull the new tube completely out of the port on the head. only pull the new 1/4" OD tube [2] one or two inches from the port on the head of the new axis-lubrication reservoir assembly that has the "OUT" label. Insert the tube until it is firmly seated in the fitting in the grease manifold [1].

Install the grease manifold [1] into the new axis-lubrication reservoir assembly[3]. The holes on top of the air input fitting [4] and grease manifold [1] must be aligned as shown [6].

3

Install the metal reservoir with grease [6]. Install the completed new axis-lubrication reservoir assembly into the cabinet.

Use the adapter bracket [1] if the holes in the cabinet do not match the holes in the head assembly. Make sure the bracket is oriented as shown. 

Note: Damage can occur over time if the vertical axis hose is not connected to an output with a check valve. Air can get into the hose and the vertical axis won't get adequate lubrication.

Connect the input air hose [5] and output grease hoses. Make sure to install the vertical axis to the output port with the check valve [3]. The other axes are installed on the hose fittings [4].

Connect the pressure switch cable to the pressure switch behind the grease manifold [2].

Grease Reservoir - Prime and Test

1

If the machine has a Classic Haas Control, do these steps:

  • Press [PARAMETER DIAGNOSTIC] (2) times to show the diagnostics page.
  • Press [CANCEL].
  • Go to the [LUBE] tab.
  • Press [WRITE/ENTER] .
  • Press [F2] to start the Axis-Lubrication Test.

If the machine has as Next Generation Control, do these steps:

  • Press [DIAGNOSTICS].
  • Go to the [MAINTENANCE] tab.
  • Press [F2] to start the Axis-Lubrication Test.

2

Perform the Axis-Lubrication Test again until you no longer get axis lubrication alarms. Wait a minimum of (1) minute between Axis-Lubrication Test cycles.

Check the level of the grease in the reservoir.

If the grease lines were nearly empty, it may be necessary to refill the axis-lubrication reservoir after you purge the lines of air. Pour the grease into the reservoir: to about 1/2" (13mm) below the threads on the reservoir.
