Setup and Assembly
Mounting to Bicycle Frame (Optional)
The pump includes a mounting bracket for convenient attachment to your bicycle frame. This bracket typically mounts under the water bottle cage.
- Identify the water bottle cage mounting points on your bike frame.
- Align the pump's mounting bracket with these points.
- Secure the bracket using the provided screws (if included) or existing water bottle cage screws.
- Place the pump into the bracket and secure it with the rubber strap.

Operating Instructions
Valve Compatibility (Presta and Schrader)
The pump head is designed to work with both Presta and Schrader valves. No internal parts need to be swapped.
- For Presta Valves: Unscrew the valve core on your tire's Presta valve before attaching the pump.
- For Schrader Valves: The pump can be attached directly to the Schrader valve.

Using as a Hand Pump
- Ensure the tire valve is ready (unscrew Presta valve core if applicable).
- Remove the dust plug from the pump head.
- Firmly press the pump head onto the tire valve. For Presta, ensure it's fully seated. For Schrader, push down until it locks.
- Flip the lever (if present) to lock the pump head onto the valve, creating a tight seal.
- Extend the pump handle and begin pumping. The non-slip threads on the handle provide a secure grip.
- Pump until the desired tire pressure is reached (up to 110 PSI).
- Unlock the lever and carefully remove the pump head from the valve.
- Replace the dust plug and screw down the Presta valve core if applicable.
Using as a CO2 Inflator
CO2 cartridges are not included with this pump. Use threaded CO2 cartridges (12g, 16g, 20g compatible).
- Ensure the tire valve is ready (unscrew Presta valve core if applicable).
- Place the soft sponge insulated sleeve over the CO2 cartridge to protect your hands from cold during discharge.
- Remove the dust plug from the pump head.
- Firmly press the pump head onto the tire valve.
- Screw the CO2 cartridge into the designated port on the pump head until it pierces the cartridge.
- Once pierced, slowly unscrew the cartridge slightly (about a semicircle turn) to release CO2 into the tire. Adjust the turn to control the flow.
- Inflate the tire to the desired pressure.
- Once inflated, fully unscrew the CO2 cartridge and remove the pump head from the valve.
- Replace the dust plug and screw down the Presta valve core if applicable.

Maintenance
- Cleaning: Wipe the pump exterior with a damp cloth to remove dirt and debris. Avoid using harsh chemicals.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the pump's piston shaft to ensure smooth operation.
- Storage: Store the pump in a dry place, away from direct sunlight and extreme temperatures. Ensure the dust plug is in place to prevent debris from entering the pump head.
- Inspect Seals: Regularly check the rubber seals and O-rings for wear or damage. Replace if necessary to maintain an airtight seal.

Safety Information
- Always wear appropriate eye protection when using CO2 cartridges.
- CO2 cartridges contain gas under high pressure. Handle with care and do not expose to heat or direct sunlight.
- Keep CO2 cartridges and the pump out of reach of children.
- Do not overinflate tires. Refer to your tire's sidewall for recommended pressure ranges.
- The CO2 cartridge will become extremely cold during discharge. Use the insulated sleeve to protect your hands.
- Ensure the pump head is securely attached to the valve before inflating to prevent accidental detachment and injury.
