Operating Instructions

Pumping Procedure:
- Preparation: Wash your hands thoroughly. Ensure the pump is clean and correctly assembled. Find a comfortable and private place to pump.
- Positioning: Center the silicone flange over your nipple. Ensure a good seal around your breast to maximize suction.
- Initiating Suction: Gently press the handle to create suction. You can adjust the suction strength by selecting one of the two gears:
- First Gear (Gentle Expression): For stimulating milk let-down or when a softer suction is preferred.
- Second Gear (Strong Expression): For faster milk expression once let-down has occurred.
- Pumping Rhythm: Mimic your baby's natural sucking rhythm. Press the handle until you feel suction, hold briefly, then release. Repeat this motion.
- Milk Flow: Milk will begin to flow into the collection bottle. Continue pumping until your breast feels empty or milk flow significantly slows.
- Finishing: Gently break the seal by inserting a finger between your breast and the flange. Remove the pump.
- Storage: Detach the bottle, cap it with the provided nipple and lid, or transfer milk to a storage bag/container. Clean all pump parts immediately after use.
