5. Maintenance

To ensure the longevity and optimal performance of your GIYO Mini Bike Pump, follow these simple maintenance guidelines:

• Keep Clean and Dry: After use, especially in wet or dusty conditions, wipe down the pump with a clean, dry cloth. Avoid using harsh chemicals.
• Lubrication: Periodically apply a small amount of silicone-based lubricant to the piston shaft to ensure smooth operation. Do not over-lubricate.
• Check Seals: Inspect the rubber seals and O-rings on the pump head for any signs of wear or damage. Worn seals can lead to air leaks and reduced efficiency. Replace if necessary.
• Storage: Store the pump in a cool, dry place, ideally mounted on your bike frame or in a protective bag, to prevent exposure to extreme temperatures or moisture.

6. Troubleshooting

If you encounter issues with your GIYO Mini Bike Pump, consider the following common problems and solutions:

• Air Leaks During Pumping:
  • Ensure the pump head is fully seated on the Presta valve and the lock lever is in the LOCK position.
  • Check the rubber seal inside the pump head for wear or damage.
  • Verify that the Presta valve's small nut is unscrewed before attaching the pump.
• Difficulty Pumping:
  • Ensure the telescopic barrel is fully extended for maximum efficiency.
  • Check if the piston shaft is clean and lightly lubricated.
  • Confirm that the valve is not clogged.
• Pump Head Stuck on Valve:
  • Ensure the lock lever is in the UNLOCK position before attempting to remove.
  • Gently twist and pull the pump head off the valve.
