EZ Air 4 Tire Inflate/Deflate System: instructions
What is in the box
- EZ Air manifold with digital gauge, inflate/deflate valve and quick connect
- Two two-tire air hoses with locking air chucks
- Carry case
Before you start
Follow the steps in this order. That is what makes all four tires come out even. Check that every connection is tight and not leaking before you start: one leak means uneven tire pressure.
Air down (deflate)
- Close the valve and fit the gauge. Make sure the valve on the manifold is closed and the gauge is on the Schrader valve.
- Connect the hoses to the manifold. Attach both tire hoses.
- Connect the hoses to the tires.
- Open the valve. Air leaves all four tires together. Close the valve now and then to read the pressure.
- Close the valve when you reach the pressure you want.
- Disconnect the hoses from the tires, then from the manifold.
Air up (inflate)
- Close the valve and fit the gauge.
- Connect each tire hose to the manifold, then to the tires.
- Connect your air source to the manifold, by the quick connect or by the Schrader valve. The system works best with the EZ Air Beast compressor.
- Start the air.
On the quick connect: open the valve, then turn on your air source.
On the Schrader valve: keep the valve closed, then turn on your air source. Stop now and then to read the pressure. - Turn off the air source and close the valve at the pressure you want.
- Disconnect the hoses from the tires, then from the manifold, and pack them in the case.
