3. Setup and Installation
3.1 Attaching the Frame Mount
- Identify suitable mounting points on your bicycle frame, typically bottle cage bosses.
- Secure the mounting bracket to the frame using the provided screws (screws are typically supplied with the bicycle frame, not the pump).
- Place the pump into the bracket and secure it with the hook and loop strap.
3.2 Valve Compatibility
The Peakini II pump head is designed to be compatible with three common valve types: Presta, Schrader, and Dunlop. The pump head automatically adjusts to the valve type.
- Presta Valve: Typically found on road bikes and some mountain bikes. Features a thinner stem with a small nut at the top.
- Schrader Valve: Common on mountain bikes, hybrid bikes, and car tires. Wider stem with a pin in the center.
- Dunlop Valve: Less common, found on some European city bikes.

4. Operating Instructions
- Prepare the Valve:
- For Presta valves: Unscrew the small nut at the top of the valve stem counter-clockwise until it is loose. Press down briefly to release a small amount of air.
- For Schrader and Dunlop valves: No special preparation is usually needed.
- Attach the Pump Head: Firmly push the pump head onto the tire valve. Ensure a tight seal to prevent air leakage.
- Inflate the Tire: Extend the pump handle to its full length. Hold the pump body steady with one hand and push the handle down firmly and smoothly to pump air into the tire. Repeat this motion until the desired tire pressure is reached.

- Remove the Pump Head: Once the tire is inflated, quickly and firmly pull the pump head straight off the valve.
- For Presta valves: Screw the small nut back down clockwise to seal the valve.
Important: Do not exceed the maximum recommended tire pressure for your bicycle tires. The Topeak Peakini II has a maximum capacity of 90 PSI.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump.
- Cleaning: Wipe the pump body with a damp cloth after use, especially if it has been exposed to dirt or moisture. Avoid using harsh chemicals.
- Lubrication: Periodically apply a small amount of silicone-based lubricant to the pump's piston shaft to maintain smooth operation. Do not use petroleum-based lubricants as they can damage seals.
- Storage: Store the pump in a dry, cool place away from direct sunlight and extreme temperatures.
- Check Seals: Inspect the rubber seals in the pump head periodically for wear or damage. Worn seals can lead to air leakage during inflation.
