Steps to Inflate
- Attach the appropriate nozzle sleeve to the inflation port.
- Connect the nozzle to the object to be inflated, then long-press the power button for 0.5 seconds to activate the pump (starts at high speed).
- Within the first 5 seconds of high-speed operation, press the power button once to switch to low speed. Press again to stop inflation.
- If running at high speed for more than 5 seconds, pressing the power button will stop operation immediately.
Important: The pump does not stop automatically. Always verify the maximum allowable pressure of the object before inflating. Overinflation may cause the object to burst.
Steps to Deflate
- Attach the appropriate nozzle sleeve to the deflation port.
- Connect the nozzle to the object and long-press the power button for 0.5 seconds to activate.
- Press the power button again to stop deflation when done.
Important: The pump does not stop automatically during deflation either. Monitor the process throughout.
Nozzle Compatibility
The PUMP2 includes multiple nozzle sleeves compatible with the following object types:
- Air mattresses, floating beds, and air pillows
- Vacuum storage bags
- Swimming rings and inflatable toys
- Camping sleeping pads

Frequently Asked Questions
- Does the HYVOHEX PUMP2 (HB2) stop automatically when the target pressure is reached?
- No. The PUMP2 does not stop automatically at any point during inflation or deflation. You must press the power button manually to stop the pump. Always check the maximum allowable pressure for the object you are inflating before use to avoid overinflation and potential damage or injury.
- What does an orange flashing light mean on the PUMP2?
- An orange flashing light has two possible meanings. During normal discharging it indicates the battery is below 10% and needs charging soon. If it appears during operation it may also signal a high-temperature warning or motor overload — in that case, stop use immediately and check that the ventilation holes are not blocked.
- Can I use the PUMP2 while it is charging?
- No. The PUMP2 cannot be used during charging. Wait until the charging cycle is complete before operating the pump. The battery indicator will show a steady white light when the battery is fully charged (100%).
- How do I switch between high speed and low speed during inflation?
- After turning the device on (long-press 0.5 seconds), the pump starts at high speed. Within the first 5 seconds of high-speed operation, press the power button once to switch to low speed, then press again to stop. If more than 5 seconds have elapsed at high speed, pressing the power button will stop the pump immediately rather than switch speeds.
