Haas Liquid Grease - Reservoir Refill

AD0121

Applies to machines built from April, 2014 to August 2022

Introduction

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].

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

If you get an axis lubrication alarm, perform 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, (P/N 93-3168), is not available refer to the Lubricant Table for Haas Machine Components.

 Note: To upgrade the plastic grease canister with a metal canister use P/N 93-2601A.

Haas Liquid Grease - Refill

1

Power off the machine. Close the primary air valve. This stops the air supply to the machine.

Pull the ring on the pressure relief valve on the air and lubrication manifold. This releases the air pressure from the system.

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

Place shop towels under the reservoir to catch any grease that may fall.

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.

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.

 Note: To prevent spills, do not overfill the reservoir.

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.

If the machine has a metal reservoir:

Place shop towels under the reservoir to catch any grease that may fall.

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

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

Install the 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

1

If the machine has a Classic Haas Control:

  • 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:

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