How To Use Certus Digital Air Machine
Step 1

First check the proper tire pressure of your vehicle. You can find this information on the inside of your vehicle’s driver side door jamb. Look for the “PSI pressure specification” for both front and back tires.
Step 2

Now that you know the proper pressure for your tires, go to the Certus Digital Air Machine and proceed with payment. Tap, Swipe or Insert Chip into credit card reader, Our machines also accept apple pay and samsung pay.
Step 3

Once payment has been approved, Select the proper AIR Pressure on the digital reader by pressing the “+ or – button” to calibrate to the proper pressure. Now you are ready to put AIR in the tire.
Note: If you are at a machine that is a combo AIR/VAC then after payment is made you will need to select either AIR or VAC. If a selection is not made the machine will timeout and no charge will be made to your credit card.
Step 4

Begin by grabbing the hose and chuck on the right side of the machine and remove the valve cap on the tire, press the chuck firmly onto the valve stem. Once your tire has reached the calibrated air pressure you will hear an audible beeping sound. Remove the chuck from the valve stem and replace the valve cap on the tire, and repeat the process for all tires.
When finished, please roll up the hose and hang the chuck back on the right side of the machine.
Flat Tire?

If a tire does not inflate or is flat, press the “flat tire” button on the machine and attach the chuck to the valve stem on the tire and press firmly until you hear a beep.
If the tire still does not inflate or continues to be underinflated then a trip to the tire shop is recommended.
