FRONT AIR PSI

Gauge

WARNING

Operating tractor with air pressure below the normal

operating range indicates a loss in air supply and

will limit the number of times the brakes can be

applied before losing front wheel brakes. Failure to

stop tractor and allow air pressure to build up may

result in damage to equipment and possible injury

or death to personnel. Seek medical attention in the

event of an injury.

This gauge registers the amount of air pressure in the

front brake system. Normal operating range is

105–140 psi (724–965 kPa) for M915A1 or

105–120 psi (724–827 kPa) for M915 through M920

vehicles.
