Swift Expression helps stimulate milk ow.
Natural Expression helps to express milk.
This is a fast, shallow suction pattern. When a baby has just latched on,
the nursing pattern is fast and shallow to start the mother's milk ow.
This is a longer, deeper suction pattern. When the mother's milk begins
to ow (letdown), the baby often changes to a longer, deeper suction
pattern.

Power Options

13
Power Options
Your Electric Breast Pump may be operated under any of the following power
supply modes:
Electrical safety can only be achieved when using the AC/DC Adapter
provided with the Pump. Use of any another adapter poses a risk to the
safety of the product and/or the user and may void the warranty.
Attach the power cord to the
breast pump.
Plug the AC/DC Adapter into an
electrical outlet.
Built-in Li-Ion Rechargeable Battery
9V AC/DC Power Adapter
Prior to rst use, charge the battery for 12
hours. If necessary, your Electric Breast
Pump can be used during this period with
the Power Cord only. For best results, allow
the battery to initially charge uninterrupted
for 12 hours.
After the initial charge, subsequent charges
will take approximately 4 hours.
The Li-Ion Rechargeable Battery will charge every time the AC/DC Adaptor is
plugged in; however, it will not charge while your Electric Breast Pump is in
use.
The Swift Expression LED and Natural Expression LED lights will ash
alternately while the battery is charging.
Note : The Li-Ion Rechargeable Battery used in this device may present a risk of re or
chemical burn if mistreated.
Do NOT disassemble the battery. Do NOT place battery near a heat source or re.
Dispose of used battery properly.
Do NOT dispose of battery in re. For long-term storage, keep battery within the
following temperature range : 32°F to 77°F (0°C to 25°C). Keep away from children.

used. The Swift Expression LED will light up. You can change the expression
setting at any time by pressing the Power/Mode button.
Switch to the Natural Expression Mode once you achieve letdown. It will
start in the last suction level used.
While pumping, use the Vacuum
Adjusting Buttons and to adjust
the suction level.
Press and hold the Power/Mode button
for more than 2 seconds to turn the
pump o. If the pump is left on but
attended for more the 30 minutes, it
will automatically shut o.

Power / Mode
Note: Make sure there is no suction on the
nipple before removing the Breastshield.
If necessary, break the suction by inserting
a nger between the Breastshield and the
breast, similar to the way you break away from
your baby's suction.

Cleaning Instructions

17
Sanitize Prior to First Use:
Before you use your Rumble Tu ® Electric Breast Pump Duo for the rst time,
disassemble and boil all parts of the Expression Collection Combo 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.
Partially dry components may aect the operation of your Electric Breast
Pump Duo. 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, 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
Tu©Electric Breast Pump Duo if any liquid is visible in the Tubing.
(See Tubing Cleaning Instructions on page 18.)
General Cleaning Instructions:
• 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.
• Set aside the Tubing. 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. If any liquid or liquid vapor is found inside the
Tubing, follow the Tubing Cleaning Instructions ( page 18) carefully before
use.
Cleaning Instructions

18
• All parts of the Expression Collection Combo Kit may be cleaned in the
upper compartment of your dishwasher or hand-washed with dish soap
in hot water.
• Do NOT use solvents or abrasives.
• Rinse with hot, clean water.
• To clean the Electric Pump Main Unit, wipe it with a 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 Tubing.
Drying Bag:
• For your convenience, you can use the included Drying Bag to hang dry all
washed and sanitized accessories.
Cleaning Instructions
Note:
Before each use, visually inspect each individual component for cracks, chips, tears,
discoloration, or deterioration, as they may aect the eciency of the Rumble Tu©Electric
Breast Pump Duo. In the event that damage to the device is observed, please discontinue
use until the parts have been replaced.
Troubleshooting

19
Decreased Suction
If it feels like the suction has decreased, try the following:
• Make sure the Breast Pump parts and accessories are assembled correctly
(see Assembly Instructions pages 8-13).
• Inspect the One-Way Valve for any tears or pinholes. This component is
critical to achieving proper suction. If damaged, replace the One-Way
Valve with one of the spare valves that is provided with your Rumble Tuff®
Electric Breast Pump.
• Detach the Tubing and Tubing Adaptor from the back of your Electric
Breast Pump Duo and place a nger over the Tubing Adaptor Inlet.
• If you do feel suction, the Electric Pump Main Unit is operating properly.
• If you do NOT feel suction or feel that the suction has decreased to an
unexpected strength, contact Rumble Tu Customer Service for assistance
(see Page 20).
Troubleshooting
Interruption of Electrical Service
If you experience an interruption of electrical service, due to a power surge
or other factors, during normal operation of your Rumble Tu® Electric Breast
Pump Duo, try the following:
• Unplug the AC/DC Adapter cord from the electrical outlet and wait for 5
seconds.
• Plug the AC/DC Adapter cord back into the electrical outlet.
• If the problem persists, try a dierent electrical outlet.
Radio Frequency Energy
This equipment generates, uses, and can radiate radio frequency energy.
If not installed properly and used in accordance with the instructions, it
may cause harmful interference with other devices in the vicinity. Try the
following:
• Reorient or relocate the device receiving interference.
• Increase the distance between the equipment.
• Connect the equipment to an outlet on a dierent circuit from that which
the other device(s) are connected.
• Consult the manufacturer or a eld service technician of the device
receiving interference for help.
• There is no guarantee that interference will not occur.

20
Pump Doesn't Start
• Make sure the Adaptor is properly plugged in.
• Ensure there's enough battery power for operation.
• When battery runs low, both the Blue and White LED Lights will ash and
then the pump will turn o.
• If the Pump still doesnt't work, contact Rumble Tu Customer Service for
assistance (see Page 20).
Low Battery
• When the battery is low, the beeper will sound twice every two minutes.
• The pump will shut down automatically when there is not enough battery
power for operation. The Swift and Natural Expression LEDS and LED
Display (with “Lo” display) will ash four times, and the beeper will sound
four times.
Breastmilk Buildup in the Breastshield Body
If breast milk doesn't appear to be draining fast enough into the Collection
Bottle, reduce the suction setting on your Electric Breast Pump Duo to allow
the milk to drain before gradually increasing.

a few minutes. If you are still experiencing pain or discomfort, consult your healthcare
professional or an international board certied lactation consultant.
