  2. Install the bottle (D) by turning it clockwise.

    NOTE: The end of the hose (A) must have a minimum length "X" inside the bottle (D) so that it does not stay entirely in.

    IMPORTANT: Keep the bottle cap (D) inside the bag supplied with it, thus avoiding its contamination.

  3. Insert the hose (A) into the filler nozzle (E) of the coolant recovery tank so that the hose penetrates 50 mm (1.9 in.) the coolant level.

    IMPORTANT: Handle the hose (A) carefully avoiding its contact with any part of the harvester, and thus contaminating the coolant.


  4. Operate the pump manually for the coolant to be sucked. If the coolant is not sucked in, push the hose (A) a little more into the filler nozzle (E) of the coolant recovery tank.

    IMPORTANT: Never turn the pump (B) upside down, keep it in an upright position. Failure to observe this procedure may cause its contamination.

  5. When the bottle (A) is full, loosen the nut (B) for air to enter and the coolant stops from being sucked.

    NOTE: After removing the bottle (A), store the pump properly, ensuring it's no contamination.
