VMC - Minimum-Quantity Lubrication - Filter - Maintenance

The Minimum-Quantity Lubrication (MQL) system supplies oil to the tool. The MQL system has an oil reservoir [2]. The oil reservoir has a filter [1]. This procedure shows you how to clean the filter. A clean filter keeps the correct oil pressure and oil flow. A dirty filter causes incorrect operation.

Prerequisites

Do this procedure if you have these conditions:
  1. The pressure to the MQL system is correct.
  2. The oil flow to the spray head is low.
If the pressure to the MQL system is low, do the VMC - Minimum-Quantity Lubrication - System Purge procedure.

Step 1

Remove these parts:
  • The reservoir bowl [1] from the oil-reservoir assembly for the MQL.
  • The oil hose [2].
  • The fitting [3] for the oil hose.

Step 2

Blow all of the debris out of the filter. Use compressed air.

note: Hold a towel under the reservoir. Catch the debris.

Step 3

Install these parts:
  • The fitting [1] for the oil hose.
  • The oil hose [2].
  • The reservoir bowl [3] for the MQL assembly.

Make sure no air bubbles are in the oil hose: Do the VMC - Minimum-Quantity Lubrication - System Purge procedure.
