  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) in the relief fitting (E) on the side of the fluid reservoir, so that the hose penetrates 50 mm (1.9 in.) the fluid level.

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

  4. Operate the pump manually for the fluid to be sucked. If the fluid is not sucked in, push the hose (A) a little more into the relief fitting (E).

    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 fluid stops from being sucked.

  6. Remove the hose from the relief fitting.

    NOTE: Be very careful when removing the hose so you do not spill any fluid on the ground.

  7. Remove the bottle (A) from the pump body by turning it counterclockwise.

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

  8. Cap the bottle (A).

  9. With the pump (A) in the vertical position, push the hose (B) down and wipe all traces of fluid.
