      DWX-43W_coolant_cleaning_01
    2. Put water in the included measuring cup and rinse out the remaining milling waste in the basket filter.

      In order to prevent clogging, after adding water and mixing the remaining milling waste in the basket filter, thoroughly rinse the basket filter so that no milling waste remains.

      DWX-43W_cleaning_filter_01
    3. Repeat Steps (1) and (2) two to three times, until the basket filter is clean.
  6. Remove the drain cap of the coolant tank, and then drain the coolant.
    IMPORTANT

    Dispose of coolant and milling waste appropriately in accordance with local regulations.

    Do not thoughtlessly dispose of them in sewers or rivers or dump them in inappropriate locations. Doing so may have an adverse impact on the environment.

  7. Clean the inside of the coolant tank.
    1. Use the included spatula and collect the milling waste in the collection tray placed inside the tank.
    2. Remove the milling waste that was collected in the collection tray.

      After removing the milling waste, use tap water and rinse off any remaining waste in the collection tray.

      DWX-43W_coolant_cleaning_06
    3. Pour a little tap water into the tank, shake the tank to the left and right, and then dispose of the dirty water.
