D45AX Air/Pneumatic System
: (not for D45FX)
The air pneumatic system on the D45AX is simple to use and understand, and easy to operate. The main
components of the air system are shown below in the Air Circuit Piping Diagram. The system operates by
depressing the Foot Valve, P/N B3P71. This gives a signal to the main 4-Way Control Valve in the Foot Valve
to change the direction—allowing air to pass to the main drive Cylinder, P/N 153S71. This pushes the saw
heads down. The speed of descent is controlled by the Speed Control Valve, P/N B3P60. The saws reverse
when the Foot Valve is released. This signals the 4-way valve to change direction of air flow to the drive
cylinder and the saw heads reverse. See additional headings for operational components. Also refer to
Diagram “D” for parts listing of air components.

Air Supply —The air supply must be turned off and all electrics disconnected before making adjustment on the
power feed. A working pressure of 75 PSI (5.4kg/cm2) is required. An industrial-type compressor of at least
3 CFM (.085 cubic meters) is recommended. An additional 3 CFM (.085 cubic meters is required for Spray
Mists. A conveniently located valve should be supplied by the user to shut off the air line.
Arms should be
Raised or lowered
by hand
when setting up machine.
FR —An Air Filter/Regulator is installed ahead of the air inlet to the machine. This system helps
prevent foreign matter from entering the system. The FR is comprised of two different components.
1. The Air Filter Bowl is located on the left side and is provided with an automatic drain. This collects and
then releases foreign matter and condensation collected by the air filter.
2. The Pressure Regulator, which is located on top of the air filter, controls the amount of air pressure allowed
into the system. An operating pressure of 75 PSI is required. (This is set at the factory.)
