Troubleshooting Guide

If you encounter issues with your dormzie ST189CD Portable Tire Inflator, please refer to the following common problems and solutions:

• Device not turning on: Ensure the battery is fully charged and correctly inserted. If using the 12V adapter, check that it is securely connected to both the inflator and the vehicle's power outlet, and that the vehicle's power outlet is functional.
