Axis Lubrication System - Grease Reservoir - Haas Liquid Grease - Refill - Introduction

This procedure tells you how to fill the grease reservoir in machines that have the purple Haas Liquid Grease (HLG) axis lubrication system.

The Haas Liquid Grease reservoir has a gauge [1], and is either plastic [2] or metal [4]. Do not use Haas Liquid Grease on a machine that uses red Mobil SHC007 [3].

Prerequisites

If the reservoir for the liquid grease does not have a pressure gauge and the grease is red, do not use purple Haas Liquid Grease. This grease will not work in the red grease system. Do the Axis Lubrication System - Grease Reservoir - SHC-007 - Refill procedure.

If you get an axis lubrication alarm, do the "Axis Lubrication System - Grease Reservoir - Haas Liquid Grease - Prime and Test" at the end of this procedure. This removes the air from the grease supply system after you fill the reservoir.

caution: Do not operate the machine if air is in the system. Damage to the ballscrews and guideways is possible without correct lubrication.

If Haas Liquid Grease, 93-2196A, is not available refer to the Lubricant Table for Haas Machine Components.

If the machine has a metal reservoir, use P/N 93-2627.

Machine Compatibility

Do this procedure for these machines:
  • All machines.

Parts Included

[A]
93-2196A
(Use this if the reservoir is plastic and the grease is purple.)
GREASE, REFILL MOBIL SHC 007/625 BLENDED - 1 QT
[B]

Axis Lubrication System - Grease Reservoir - Haas Liquid Grease - Refill

Step 1

If the machine has a metal reservoir, go to Step 3.

If the machine has a plastic reservoir, use the supplied wrench to loosen and remove the grease reservoir.

Inspect the reservoir for cracks or damage. Replace the reservoir if it is damaged, chipped, or cracked.

Step 2

Pour the HAAS LIQUID GREASE (HLG) [A] into the reservoir to about 1/2" (13 mm) below the threads on the reservoir.

note: It can be necessary to fill the reservoir again after you remove air from the system.

Install the reservoir and tighten it with the wrench.

caution: The reservoir head has a stop. When you tighten the reservoir, do not try to tighten the reservoir after you feel it stop.

Step 3

Do this step if the machine has a metal reservoir.

Remove the empty reservoir. Use an automotive oil filter wrench to loosen it if the reservoir is too tight to loosen by hand.

Remove the plastic cap from the new reservoir. Add a light film of lube to the gasket on the reservoir.

Install the new reservoir [B]. Use your hand to tighten it until the gasket makes contact with the reservoir head. Tighten another 3/4 turn.

Axis-Lubrication System - Grease Reservoir - Prime and Test

This procedure tells you how to prime the axis lubrication system.

Step 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 a Next Generation Control, do these steps:

  • Press DIAGNOSTICS.
  • Go to the Maintenance tab.
  • Press F2 to start the Axis-Lubrication Test.

Step 2

Do 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" (13 mm) below the threads on the reservoir.

Conclusion

If air is in the axis lubrication system, alarms can occur. This is not a problem. Alarms can occur for several lubrication cycles after you fill the grease reservoir.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
