Troubleshooting
If you encounter issues with your Slime 40052 Tire Inflator, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inflator does not turn on. | No power supply; loose connection; blown fuse (12V). | Ensure power cord is securely plugged in. Check vehicle's 12V outlet fuse or home outlet circuit breaker. Try a different power source. |
| Inflator runs but does not inflate or inflates slowly. | Air hose not securely attached; valve stem cap not removed; leak in hose/connection; item valve blocked. | Ensure air hose is tightly twisted onto valve stem. Remove valve stem cap. Check hose and connections for leaks. Clear any obstructions in the item's valve. |
| Inaccurate pressure reading. | Sensor calibration issue; external factors (temperature). | Ensure the inflator is on a stable surface. Compare reading with a known accurate pressure gauge. If discrepancies persist, contact customer support. |
| Unit overheats and shuts off. | Prolonged continuous use. | Allow the unit to cool down for at least 10-15 minutes before resuming operation. Avoid continuous operation for extended periods. |
