4. Setup

4.1 Mounting the Pump to Your Bicycle Frame

1. Locate the water bottle cage bosses on your bicycle frame.
2. Position the mounting bracket over the bosses. The bracket is designed to fit most standard frame tubes.
3. Use the provided screws to securely attach the bracket to the frame. Ensure the bracket is tightened firmly but do not overtighten to avoid damaging the frame or bracket.
4. Slide the Topeak Dual DXG Mini Pump into the bracket. The pump should snap securely into place.
5. If desired, a standard water bottle cage (not included) can be mounted over the pump bracket using the same screws.

5. Operating Instructions

5.1 Preparing the Tire Valve

• For Presta Valves: Unscrew the valve stem lock nut (if present) and press down briefly on the valve stem to release any trapped air.
• For Schrader Valves: No special preparation is typically needed, but ensure the valve cap is removed.

5.2 Attaching the SmartHead™ Connector

1. Remove the dust cap from the pump head.
2. Firmly press the SmartHead™ connector onto the tire valve. The SmartHead™ automatically detects and adapts to either Presta or Schrader valves.
3. Ensure a tight seal. If air leaks, adjust the pump head position on the valve.

5.3 Inflating the Tire

1. Once the pump head is securely attached, begin pumping by extending and compressing the pump handle. The Dual DXG pump inflates on both the push and pull strokes, providing efficient air delivery.
2. Monitor the in-line gauge to reach your desired tire pressure. The maximum recommended pressure for this pump is 120 PSI (8 bar).
3. Avoid excessive side-to-side movement of the pump while inflating, as this can stress the valve stem and potentially cause damage to the tube.

5.4 Detaching the Pump

1. Once the desired pressure is reached, quickly and firmly pull the SmartHead™ connector straight off the valve.
2. Replace the valve cap (if applicable) and the pump's dust cap.

6. Maintenance

• Cleaning: Wipe the pump body with a damp cloth to remove dirt and grime. Avoid using harsh chemicals.
• Lubrication: Periodically apply a small amount of silicone-based lubricant to the pump's piston shaft to ensure smooth operation.
• Inspection: Regularly check all components, especially the base and head of the pump, for any signs of loosening or damage. Ensure all parts are securely fastened.
• Storage: Store the pump in a dry, clean environment when not in use.

7. Troubleshooting

• Difficulty reaching high pressure: Mini pumps require more effort to reach high pressures compared to floor pumps. Ensure a firm grip and consistent strokes. If the issue persists, check for leaks at the valve connection.
• Air leaking from valve connection: Ensure the SmartHead™ connector is fully and squarely seated on the valve stem. The valve stem itself might be damaged or have a loose core (for Presta valves).
• Pump feels loose or parts have fallen off: Regularly inspect the pump for any loose components, especially at the base. Tighten any screws or parts that may have come loose during use or transport.
• Gauge not reading correctly: Ensure the pump is properly connected to the valve. If the gauge consistently reads incorrectly, the pump may require servicing.
