This is an addendum instruction for the pressure limiter and does not cover the safe operation of the machine, tire/rim match, or evaluation of safe wheels and tires, or instructions covering the safe inflation processes. If you need copies of operating instructions call 1-800-688-6359 or refer to the internet at www.ammcoats.com.

Note: Fittings have a sealant coating as purchased. If

absent, be sure to apply teflon tape or thread sealant to any male threads at installation.

Check connections for zero leakage.

Pressure Limiter Maintenance

Operating a tire changer with a defective, improperly adjusted, or by-passed pressure limiter could cause an operator to accidentally over pressurize a tire, resulting in a tire explosion with severe injury or death to the operator or bystanders.

Always be sure that the pressure limiter is present and is operating properly.

Never inflate tire above manufacturer’s recommended pressure after bead is seated. Pressure limiter is set at 60 PSI. Any required inflation above 60 PSI should be performed in an inflation chamber/safety cage or securely mounted on the vehicle if an inflation chamber is not available. A tire explosion may cause personal injury or death to operator or bystanders.

The pressure limiter helps prevent inflation of standard size or larger tires or tubes beyond 60 PSI to minimize risk of explosion. This device is for the safety of the operator and bystanders. Proper operation of the pressure limiter is essential to safe operation of the machine.

Check operation of the pressure limiter as shown and described below at least monthly and each time the machine is serviced:

1. Remove tires and/or wheels from the machine.

2. Connect the inflation hose to an empty service

tank with a pressure gauge (gauge should read 0). Use a service tank with a pressure rating of at least 100 PSI and with a pressure relief valve set at the tank’s rated pressure.

3. Depress inflation pedal to position 1 to start air-

flow through the hose and into the tank. Maintain a steady pressure for constant flow.

4. Watch the rising pressure on the tank gauge and

the gauge on the machine. Machine gauge should cycle between check and inflation pressures while tank gauge climbs steadily. As tank pressure reaches 60 PSI, the pressure limiter should stop the airflow automatically. Both gauges should read 60 PSI ± 5 PSI.

5. Release inflation pedal. Check manual release

valve function by pressing the button and releasing pressure from the tank until it reaches 50 PSI. Disconnect inflation hose, and release air inside tank.

6. Replace pressure limiter if it fails to cycle properly

during inflation, if it fails to shut air supply off at 60 PSI, or if it malfunctions in any other way. Do not operate machine with a faulty pressure limiter.
