If possible, wait until your breastmilk supply and breastfeeding schedule are well established. Wash your hands thoroughly and make sure your breasts are clean and the manual breast pump is sterilized and assembled correctly. Press the ComfortFit flange of the pump firmly against your breast; making sure the seal is secure so that no air can escape. As you gently push down on the pump handle you will feel the suction on your breast. To start with the let down phase, set the stem in the top (first) notch of the handle and squeeze the handle. Your breastmilk will soon start flowing even though you may not use all the suction the pump can generate. Once breastmilk is flowing (1 to 2 minutes) change to the expression phase. To switch to expression phase, gently press the 'Push' part at the tip of the handle to set the handle to the second (bottom) notch of the stem. Continue to squeeze and release the handle to find the appropriate suction pressure. The suction pressure changes based on how hard you squeeze the handle. Expressing in comfort is more important than setting a strong suction pressure. Please express milk at a suction pressure that feels appropriate for you. Always refer to in pack product manual for full usage instructions. Please remember: Should pumping become very painful or uncomfortable, you should stop using the pump and consult your doctor or breastfeeding advisor.

Do not continue pumping for more than five minutes at a time if no result is achieved. Try expressing at another time during the day. Sterilize: Prior to using your pump for the first time, disassemble it (remove silicone diaphragm and stem, ComfortFit flange and white valve) and boil all parts, including bottle stand, for 10 minutes. Remove all parts from water immediately after boiling. Completely air dry before assembly and before the next use. Note: It is essential that you use enough water to keep the parts freely floating while boiling. Cleaning: The breast flange, bottle, handle and bottle stand may be cleaned in the upper compartment of your dishwasher or hand washed with dish soap and hot water. Do not use solvents or abrasives. Rinse with hot, clean water. The white valve, silicone diaphragm, stem and the ComfortFit flange can be washed in the dishwasher; however, we recommend washing them by hand to prevent loss and to extend their usefulness. Completely air-dry all parts on a clean towel or drying rack. Note: Use caution when cleaning the small white valve. It is important for proper suction. Do not use excessive force and do not clean with a baby bottle brush or a nipple brush. Gently wash by hand in hot, soapy water and rinse under hot running water.
