3.2 Preparing for Inflation (Presta Valve Only)

This pump is designed exclusively for Presta valves. Before attaching the pump, ensure your tire has a Presta valve.

1. Unscrew the small knurled nut on the tip of the Presta valve counter-clockwise until it is loose.
2. Press down briefly on the valve stem to release a small amount of air. This ensures the valve is open and ready for inflation.

4. Operating Instructions

4.1 Attaching to Valve

1. Remove the integrated dust cap from the pump head.
2. Firmly push the pump head onto the Presta valve stem until it is fully seated.
3. Engage the thumb lock lever by pushing it down to secure the pump head to the valve, creating an airtight seal.

4.2 Inflating Tires

The Roadie DA G features a dual-action design for faster inflation.

1. Hold the pump firmly with one hand on the handle and the other on the barrel.
2. Push and pull the handle in a smooth, continuous motion. Air will be delivered into the tire on both the push and pull strokes.
3. Continue pumping until the desired pressure is reached, as indicated on the integrated gauge.

4.3 Reading the Gauge

The analog gauge provides real-time pressure readings in both PSI and Bar.

• The outer ring of the gauge typically displays pressure in PSI (Pounds per Square Inch).
• The inner ring displays pressure in Bar.
• Refer to your tire's sidewall for the recommended pressure range.

4.4 Detaching the Pump

1. Once the desired pressure is achieved, disengage the thumb lock lever by flipping it up.
2. Carefully pull the pump head straight off the valve stem.
3. Screw the small knurled nut on the Presta valve tip clockwise until it is finger-tight to seal the valve.
4. Replace the integrated dust cap on the pump head.

5. Care and Maintenance

• Cleaning: Wipe the pump clean with a damp cloth after use, especially if it has been exposed to dirt or moisture. Avoid using harsh chemicals.
• Storage: Store the pump in a dry place, away from direct sunlight and extreme temperatures. Ensure the dust cap is in place to protect the valve head.
• Lubrication: Periodically apply a small amount of silicone-based lubricant to the pump's plunger shaft to maintain smooth operation. Do not over-lubricate.
• Inspection: Regularly check the pump head and thumb lock lever for wear or damage. Ensure the gauge is clear and readable.

6. Troubleshooting

• Pump not inflating tire:
  • Ensure the Presta valve nut is unscrewed and the valve has been briefly depressed to open it.
  • Verify the pump head is fully seated on the valve stem and the thumb lock lever is securely engaged.
  • Check for any visible damage to the pump's seals or O-rings.
• Air leaking from valve connection:
  • Re-seat the pump head firmly and ensure the thumb lock lever is fully engaged.
  • Inspect the rubber gasket inside the pump head for wear or damage.
• Inaccurate gauge reading:
  • Compare the reading with another known accurate gauge if possible.
  • Ensure the pump is held steady during inflation to avoid erratic readings.
