What’s in the box
Compatibility
The GEAROPT Manual Hand Pump is designed for compatible GEAROPT Mini Tank systems.
Before use, please confirm your Mini Tank model, connector type and required filter setup. Do not use the pump with non-compatible cylinders or unauthorized adapters.
Safety First
The GEAROPT Manual Hand Pump is a high-pressure filling support tool. Manual filling requires correct operation, time and physical effort.
Always:
Read the product manual before use.
Use the required filter system.
Fill only with clean, dry, breathable air.
Check all connections before filling.
Do not exceed the rated working pressure of your Mini Tank.
Stop using the pump if abnormal heat, leakage or resistance occurs.
Do not use oxygen, Nitrox, industrial gas, contaminated air or any unauthorized gas source.
The Manual Hand Pump is not a toy and should only be used by responsible users who understand the product instructions.
Important Note：Manual pumping is a portable support option, not the fastest filling method. For frequent refilling, a compatible
high-pressure compressor or proper breathing-air filling source may be more practical.
