Uharbour 4 Tire Inflation System User Manual

1. Introduction

The Uharbour 4 Tire Inflation System is an advanced tool designed to streamline tire maintenance for vehicles with up to a 125-inch wheelbase. This system allows for efficient and precise inflation, deflation, and equalization of pressure across all four tires simultaneously, saving valuable time and effort. It ensures optimal tire performance, extends tire life, and enhances fuel efficiency by maintaining balanced tire pressure.

3. Setup

Follow these steps to set up your Uharbour 4 Tire Inflation System:

1. Assemble the Main Unit: Connect the digital pressure gauge to the air manifold. Ensure all connections are secure. Use Teflon tape on threaded connections for an airtight seal if necessary.
2. Attach Hoses: Connect the two sets of air hoses to the air manifold using the quick connectors. Each set of hoses is designed to reach two tires.
3. Connect to Air Source: Attach the main quick connector from the air manifold to your air compressor. The system is compatible with standard 1/4 IM male couplers found on popular air compressors like Smittybilt, Viaire, and Warn Powerplant.
4. Prepare for Use: Ensure the slide valve on the main unit is in the correct position for inflation or deflation as desired.

4. Operating Instructions

The Uharbour 4 Tire Inflation System simplifies tire pressure management. Always ensure the digital pressure gauge is turned on before connecting to the air valve for accurate readings.

4.1. Inflating Tires

1. Connect to Tires: Attach the air chucks to all four tire valves. The lock-on design ensures a secure connection without air leakage.
2. Set Slide Valve: Push the slide valve on the main unit upwards for inflation.
3. Activate Air Compressor: Turn on your air compressor. The digital gauge will display the real-time pressure of all connected tires, which will equalize as air flows.
4. Monitor Pressure: Continue inflating until the desired PSI is reached. The system allows for rapid inflation, typically taking less than 2 minutes to inflate all four tires from 20 to 40 PSI.
5. Disconnect: Once the target pressure is achieved, turn off the air compressor, then disconnect the air chucks from the tire valves.

4.2. Deflating Tires

1. Connect to Tires: Attach the air chucks to all four tire valves.
2. Set Slide Valve: Gently pull the slide valve on the main unit downwards to release air. The digital gauge will show the decreasing pressure.
3. Monitor Pressure: Release air until the desired PSI is reached. The system ensures all tires deflate equally.
4. Disconnect: Once the target pressure is achieved, push the slide valve back to the neutral position (or upwards to stop deflation), then disconnect the air chucks from the tire valves.

5. Maintenance

To ensure the longevity and optimal performance of your Uharbour 4 Tire Inflation System, follow these maintenance guidelines:

• Cleaning: After each use, wipe down the hoses, manifold, and digital gauge with a clean, damp cloth to remove any dirt or debris.
• Storage: Store the system in its durable storage bag in a cool, dry place away from direct sunlight and extreme temperatures. Ensure hoses are neatly coiled to prevent kinks.
• Connections: Periodically check all quick connectors and threaded fittings for wear or damage. Replace any worn parts to maintain an airtight seal.
• Digital Gauge Battery: The digital pressure gauge is battery-powered. If the display becomes dim or unresponsive, replace the batteries as needed.
• Teflon Tape: Reapply Teflon tape to threaded connections if you notice any air leaks.
