PRO TARGET
PRESSURE
The TIREMAAX PRO controller is pre-set at the factory,
therefore additional setup is normally not required. If
a change to the inflation or deflation pressure settings
is required, follow these instructions.
NOTE: The following procedures assume the trailer
is not connected to a truck and the system
integrity is good.
IMPORTANT: The system must be free of air leaks
prior to performing these procedures.
Refer to CHECKING FOR AIR LEAKS on
page 44.
WARNING: Emergency air supply must be
available at the Emergency supply
port on the controller to enable
TIREMAAX PRO operation. Supplying
air at the emergency gladhand will
also release trailer brakes.
REQUIRED TOOLS AND RESOURCES
The following tools and resources are required to
adjust TIREMAAX PRO controller settings.
• Clean, dry shop air capable of supplying at least
15 psi above inflation pressure listed on controller
decal.
• Tire pressure gauge.
