Step-by-Step Guide: How to Use a Hercules Tire Inflator
Using your new inflator correctly ensures safety and optimal performance. This practical guide walks you through the entire inflation process.
Pre-Inflation Setup and Preparation
Begin by gathering your equipment in a well-lit, stable area. Ensure your Hercules 20V battery is fully charged and securely inserted into the inflator. Check your vehicle’s recommended tire pressure, usually found on the driver’s side door jamb sticker.
- Remove the valve stem cap from the tire you are inflating.
- Firmly press the inflator’s hose chuck onto the valve stem until you hear a slight hiss of air.
- Power on the unit and use the +/- buttons to set your desired target pressure on the digital display.
Executing the Inflation Process
With the target pressure set, press the trigger or start button to begin. The inflator will run automatically. You do not need to hold the trigger continuously during operation.
The integrated auto-shutoff function is the key feature here. The unit will stop automatically once it reaches your preset pressure. Listen for the motor to cut off, indicating the process is complete.
Safety Note: Never leave the inflator unattended while running. If the motor sounds strained or the unit gets excessively hot, stop immediately and allow it to cool. Always inflate tires to the manufacturer’s recommended PSI, not the maximum on the tire sidewall.
Post-Inflation Steps and Maintenance
After the inflator shuts off, quickly remove the hose chuck from the valve stem. Immediately replace the valve stem cap to keep out dust and moisture. This preserves the valve core and prevents slow leaks.
Proper maintenance extends your tool’s lifespan. Store the inflator in a clean, dry place away from extreme temperatures. Periodically check the air filter and clean it according to the user manual to ensure proper airflow and motor cooling.
- Storage: Wind the power hose neatly to prevent kinks and damage.
- Battery Care: Store batteries at room temperature and recharge them every 3-6 months if not in use.
- Accessories: Keep extra valve adapters in the storage compartment so they’re always available.
