5. Operating Instructions

5.1. Valve Type Selection (Schrader & Presta)

The pump head is designed to work with both Schrader and Presta valves. No additional adapters are needed for switching between valve types.

• For Presta Valves: Ensure the pump head's internal mechanism is in the 'UP' position. This is typically indicated by a 'P' or an arrow pointing up.
• For Schrader Valves: Ensure the pump head's internal mechanism is in the 'DOWN' position. This is typically indicated by an 'S' or an arrow pointing down.
• To switch, simply push or pull the internal component of the pump head as indicated by the markings.

5.2. Inflating a Bicycle Tire

1. Step 1: Prepare the Valve. Remove the dust cap from your tire valve. If using a Presta valve, unscrew the valve core lock nut.
2. Step 2: Pull out the Hose. Gently pull out the flexible EPDM rubber hose from the pump body.
3. Step 3: Choose the Right Valve. Adjust the pump head to match your tire's valve type (Schrader or Presta) as described in Section 5.1.
4. Step 4: Connect to Valve. Firmly attach the pump head to the tire valve. Ensure a tight seal to prevent air leakage.
5. Step 5: Start to Inflate. Begin pumping by pushing and pulling the pump handle. Continue until the desired pressure is reached.
6. Step 6: Disconnect and Secure. Once inflated, quickly detach the pump head from the valve. Screw the Presta valve lock nut back down (if applicable) and replace the dust cap. Return the hose to its storage position within the pump body.

5.3. Using Included Adapters

The ball needle and gas nozzle can be attached to the pump hose for inflating other items:

• Ball Needle: Screw the ball needle onto the pump hose. Use it to inflate sports balls like basketballs, soccer balls, etc.
• Gas Nozzle: Attach the gas nozzle to the pump hose. This is suitable for inflating swimming rings, inflatable toys, and other low-pressure inflatables.

6. Maintenance

• Cleaning: Wipe the pump exterior with a damp cloth to remove dirt and grime. Avoid using harsh chemicals.
• Storage: Store the pump in a dry place, away from direct sunlight and extreme temperatures. Ensure the hose is properly retracted into the pump body.
• Check Seals: Periodically inspect the rubber seals and O-rings in the pump head for wear and tear. Replace if necessary to maintain an airtight seal.
• Lubrication: A small amount of silicone grease can be applied to the piston shaft occasionally to ensure smooth operation, but avoid over-lubrication.

7. Troubleshooting

• Difficulty Pumping / No Air Flow:
  • Ensure the pump head is securely attached to the valve and the correct valve type (Schrader/Presta) is selected.
  • Check for any blockages in the hose or pump nozzle.
  • Inspect rubber seals for damage or improper seating.
• Air Leaking from Valve Connection:
  • Re-attach the pump head firmly to the valve, ensuring a tight fit.
  • Verify the correct valve type setting on the pump head.
  • Check the valve stem on your tire for damage or a loose core.
• Pump Becomes Hard to Operate at Higher Pressures:
  • This is normal for mini pumps as pressure increases. Continue pumping with steady strokes.
  • Ensure the pump is clean and lubricated for smooth piston movement.
