5. Maintenance
- Clean Regularly: Wipe down the pump barrel and hose with a damp cloth to remove dirt and grime.
- Inspect Hose and Head: Periodically check the hose for cracks or damage and ensure the TwinHead DX5 is free of debris and seals properly.
- Lubricate Moving Parts: If the pumping action becomes stiff, apply a small amount of silicone-based lubricant to the pump shaft.
- Store Properly: Store the pump in a dry place, ideally with the hose secured in its dock, to prevent damage and prolong its lifespan.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Air leaks from valve connection | Pump head not fully engaged or worn seal. | Ensure pump head is pushed firmly onto valve and lever is fully locked. Inspect rubber seals in pump head for wear and replace if necessary. |
| Difficulty pumping / stiff action | Lack of lubrication or internal debris. | Apply silicone-based lubricant to the pump shaft. Check for any obstructions in the barrel. |
| Inaccurate pressure reading | Gauge malfunction or external factors. | Compare reading with another reliable gauge. Ensure pump head is securely attached without leaks. |
| Pump not inflating tire | Valve core issue or severe leak. | Check if the valve core is loose or damaged. Ensure there are no punctures in the tire or tube. |
