Introduction
The ATsafepro 4-Tire Inflation/Deflation System is designed for efficient and precise tire pressure management. This system allows for simultaneous inflation or deflation of all four tires, significantly reducing the time required for tire maintenance. It is ideal for various vehicles, including those with wheelbases up to 155 inches, and ensures optimal tire pressure for enhanced fuel efficiency, tire longevity, and overall vehicle performance.

Setup Guide
- Unpack the System: Remove all components from the storage bag.
- Connect to Air Source: Attach your air compressor (not included) to the main inlet of the manifold. Ensure a secure connection. The system is compatible with various air sources, including portable and garage compressors.
- Attach to Tires: Connect each of the four quick-connect chucks to the valve stems of your vehicle's tires. Ensure the chucks are fully engaged and locked onto the valve stems to prevent air leakage. The system is designed to fit vehicles with wheelbases up to 155 inches.

Operating Instructions
Inflation
- Ensure Connections: Confirm all four tire chucks are securely attached to the valve stems and the system is connected to your air compressor.
- Set to Inflation Mode: The manifold features a slide valve to switch between inflation and deflation. Ensure the valve is set to the "Inflation" position.
- Activate Air Compressor: Turn on your air compressor. The digital gauge on the manifold will display the current tire pressure.
- Monitor Pressure: Continuously monitor the digital gauge until the desired tire pressure is reached. The system will equalize pressure across all four tires simultaneously.
- Disconnect: Once the target pressure is achieved, turn off the air compressor, then carefully disconnect the chucks from the tire valve stems.
Deflation
- Ensure Connections: Confirm all four tire chucks are securely attached to the valve stems.
- Set to Deflation Mode: Ensure the slide valve on the manifold is set to the "Deflation" position.
- Monitor Pressure: The digital gauge will display the current tire pressure as air is released. Allow air to escape until the desired lower pressure is reached.
- Disconnect: Once the target pressure is achieved, carefully disconnect the chucks from the tire valve stems.

Maintenance
- Cleaning: After each use, wipe down the manifold, digital gauge, and hoses with a clean, damp cloth to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaners.
- Hose Inspection: Regularly inspect the hybrid air hoses for any signs of wear, cracks, or damage. The hybrid construction provides strength and flexibility, but proper care ensures longevity.
- Storage: Always store the system in its included storage bag when not in use. This protects the components from dust, dirt, and physical damage, and keeps them organized for easy transport. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Digital Gauge Care: Protect the digital gauge from impacts and moisture. If the display becomes dim or unresponsive, check the battery (if replaceable) according to the manufacturer's instructions.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Pressure Reading | Loose connection; Gauge malfunction; Low battery in digital gauge. | Ensure all connections are secure. If problem persists, contact support for gauge calibration or replacement. Check and replace digital gauge battery if applicable. |
| Air Leakage | Improperly attached chucks; Damaged hose or O-ring; Loose manifold connections. | Re-attach chucks firmly to valve stems. Inspect hoses and O-rings for damage and replace if necessary. Tighten all manifold connections. |
| System Not Inflating/Deflating | Air compressor not active/functional; Slide valve in wrong position; Blockage in system. | Ensure air compressor is on and providing air. Verify slide valve is in the correct Inflation/Deflation position. Check hoses for kinks or blockages. |
