Caution: Take care when cleaning the One-Way Valve. If it gets damaged, your breast pump will not
function properly. To clean the One-Way Valve, rub it gently between your ngers in warm soapy water,
then rinse thoroughly in clean warm water. Do not insert any objects into the One-Way Valve as this may
damage the valve.

Cleaning Instructions

Unless otherwise instructed by your healthcare provider, follow these sanitizing and cleaning instructions.

Sanitize Prior to First Use:

Before you use your Rumble Tuff

®

Duo Electric Breast Pump for the rst time, disassemble and boil all parts of the

Expression Collection Combo Kit and the Manual Diaphragm Add-on Kit in water for 10 minutes.

● Be sure to use enough water to keep all parts aoat while boiling.

● Do NOT boil Tubing or Tubing Adapter.

● Remove all parts from the water immediately after sterilizing. To avoid scalds and burns, do NOT touch the product
with bare hands right after sterilizing.

● Completely air-dry or towel-dry before reassembling for next use.
Partially dry components may affect the operation of your Electric Breast Pump. Please ensure that all parts are
completely dry before use.

Before Each Use:

● Wash your hands thoroughly with soap and warm water before handling the Expression Collection Combo Kit, the
Electric Breast Pump, the Manual Pump Add-On or any Expression Collection parts or attachments.

● Make sure all parts are clean and dry.

● Ensure the Tubing is free from any liquid. Do NOT operate your Rumble Tuff Duo Electric Breast Pump if any

liquid is visible in the Tubing. (See Tubing Cleaning Instructions on page 33.)

General Cleaning Instructions:

● Set aside the Tubing and Tubing Connector. Under the normal working conditions of the pump, the diaphragm
prevents the back-ow of milk. Therefore, these items do not need to be washed. In case of nding any liquid or
liquid vapor inside the Tubing, follow the Tubing Cleaning Instruction (on page 33) carefully before use.

● All parts of the Expression Collection Combo Kit or Manual Diaphragm Add-On Kit may be cleaned in the upper
compartment of your dishwasher or hand washed with dish soap in hot water.

English 32

Cleaning Instructions (Continued)

● Do NOT use solvents or abrasives.

● Rinse with hot, clean water.

● To clean the Electric Pump Main Unit, wipe it with a wet wipe or damp cloth, using only water or water mixed with a
mild soap.

Tubing Cleaning Instructions:

● Wipe the outside of the Tubing with a clean, damp cloth. Avoid getting water or other uids inside the Tubing.

● If liquids are found inside Tubing, rinse the Tubing with clean hot water. Hang to AIR DRY COMPLETELY BEFORE
USING. Do NOT insert any object into the Tubing.

Note: Before each use-visually inspect the individual components for cracks, chips, tears, discoloration or deterioration;

as they may affect the efciency of the Rumble Tuff

®

Duo Electric Breast Pump. In the event that damage to the

device is observed, please discontinue use until the parts have been replaced.

English 33

Breastmilk Storage Guidelines

Check with your healthcare provider or an International Board Certified Lactation Consultant for specific storage
instructions. This information is based on current research and applies to mothers who have healthy, full-term babies
who are storing their milk for home use.

Important Notes:

● STORAGE CONTAINERS: The best option for storing human milk is glass or hard-sided plastic containers with
well-tting tops. When you are freezing your breastmilk, do not ll the container more than 3/4 full to allow for
expansion from freezing. Store milk in the main refrigerator or freezer compartment, away from the door, to avoid
changes in temperature that may compromise the milk.

● RE-WARMING THE FROZEN MILK: Frozen milk can be thawed in the refrigerator overnight or under cool running
water. Gradually increase the temperature of the water to heat the milk to feeding temperature. Be sure to use
thawed milk within 24 hours. Discard any leftovers.

● RE-WARMING THE REFRIGERATED MILK: Refrigerated milk can be warmed by running under warm water for
several minutes. ALWAYS test the temperature of the milk on the inside of your wrist before feeding it to your baby.
The milk should feel warm, not hot.

● WHAT TO DO: Storing milk in 2 to 4 oz amounts may reduce waste. Write the date you expressed your milk on the
container (include your baby's name on the label if your baby is in a daycare setting). Use the oldest milk rst. Throw
away previously frozen milk that is not used within 24 hours.

● WHAT NOT TO DO: Do NOT heat milk directly on the stove. Do NOT thaw in hot or boiling water. Do NOT microwave
milk, as microwaving alters the composition of the milk and may create hot spots that may burn your baby. Do NOT
refreeze thawed milk.

● THAT'S WEIRD: Human milk may separate into a milk layer and a cream layer when it is stored. This is normal.
Gently swirl to redistribute the cream before giving to baby. Sometimes thawed milk may smell or taste soapy. This is
due to a breakdown in the milk fats. The milk is safe and most babies will still drink it.

● IS IT DANGEROUS: Expressed milk can be kept in a common refrigerator at the workplace or day care center. The
US Center for Disease Control (CDC) and the US Occupational Safety and Health Administration (OSHA) agree that
human milk is not among the body uids that require special handling or storage in a separate container.

milk within 1 to 2 hours after the baby is
nished feeding.

Tips

Pumping Tips:

The most important and successful part of pumping is the let-down reex. The let-down reex is when your milk begins
to ow freely.

● Try relaxing with a warm, wet compress on your breasts.

● Drink plenty of uids.

● Avoid outside distractions.

● Visualize yourself happy, well rested and successful at pumping.

● Sometimes a light circular massaging of the breasts prior to and/or during a pumping session will help your let-down
reex start/continue.

● Go to a Non-stressful environment.

● Use a comfortable chair that gives lower back support with or without a footstool. After all, you're the one who has to

be comfortable.

Depending on your health and milk production condition, you may be able to achieve more than one let down in one
pumping session. Most mothers have more than one let-down while breast feeding and don't even notice the change.
To achieve multiple let-downs which mimics the natural reex found in breast feeding, you can switch back and forth
between Swift Expression and Natural Expression just by pressing the Expression Button.

Remember that successful pumping is a learned skill. Don't get discouraged, and keep working at it to obtain the best
results. Breastmilk is produced on a supply and demand basis; expressing your breastmilk regularly stimulates and
maintains your milk supply.

If it feels uncomfortable or painful on your breasts while using the Pump, try decreasing the suction level by rolling the
Vacuum Adjusting Wheel down (-). You may also try pumping with/without the Silicone Cushion. If these tips do not
help, turn the product off and remove the pump from your breasts for a few minutes. If you are still experiencing pain or
discomfort, consult your healthcare professional or an international board certied lactation consultant.

Using the Manual Pump:

1. Hold the Manual Breast Pump to your breast so that your
nipple is centered inside the Breastshield. Then squeeze the
handle toward the bottle to test the suction.

Note: If an adjustment is necessary, turn the round knob of the
Adjusting Valve until the suction is comfortable.

2. You can adjust the suction level by turning the round knob on
the top of the Adjusting Valve Stem. Turn clockwise to increase
the suction and counter-clockwise to decrease it.

Note: Do not over-turn the Adjusting Valve, as it will cause the
Adjusting Valve to bulge and leak air, creating a suction
problem. Make sure the gap opening on top of the Adjusting
Valve is lined up properly on the top of the Valve Stem so the
Adjusting Valve turns smoothly. If necessary, re-adjust the
Adjusting Valve by turning back and forth a few times.

Note: There are two recesses for attaching the handle to the Manual Pump. You can toggle between these two settings by pushing
the Adjusting Valve Stem away from the “U” shape tip of the Handle to dislocate the connection. Reattach the tip of the Handle using a
different recess on the Adjusting Valve Stem.

Swift Expression Setting:

This setting is for a fast, shallow suction. Often, when a baby is hungry or has just "Latched-On," their nursing pattern is fast
and shallow to start the mother's milk ow.

Natural Expression Setting:

This setting is for longer, deeper suction. When the mother's milk begins to ow into the baby's mouth (let-down), they often
naturally change to a longer, deeper suction pattern.
