5. Setup
Before using the pump, ensure it is fully charged. Attach the extension hose to the pump and then to the tire valve.
Attaching the Extension Hose
The extension hose is specifically designed for folding bikes, scooters, and other small tire applications. It is crucial to use the extension hose for TPU valves.
