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

    End of hose (A) must have a minimum length "X" inside bottle (D) to avoid it enters entirely.

    Keep cover of bottle (D) inside the supplied bag to avoid its contamination.

  3. Insert hose (A) into filler neck (E) of coolant recovery tank so that the hose is at 50 mm (1.9 in.) from coolant level.

    Handle hose (A) with care to avoid it enters in contact with any tractor part and contaminates the coolant.


  4. Operate pump manually to permit suction of coolant. If coolant is not sucked in, insert hose (A) into filler neck (E) of coolant recovery tank.

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

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