ƒ Press the hoses firmly back into the push-in fittings. Identify and replace any leaking
hoses or switches. Turn router motor switches back on.
Solution Two Steps:
The air pressure may need to be adjusted at the pressure regulator inside the control box. The air
pressure from the regulator determines the drill feed rate and overall speed of the machine. The
factory setting is 85 PSI. This regulator is adjustable and should be checked periodically as well
as any time the performance of the machine becomes unstable or slow. Its important that at least
85 PSI is going into the machine from the compressor. Other machines on the same line as your
Castle machine can affect this pressure.
NOTE: Too slow will burn drill bits and cause separation at the shank. Too fast
will put too much pressure on the drill bits and cause them to break and/or cut
over-sized holes.

Pull-click the knob at the back of the case. (Figure 20) Back it off fully - counter-
clockwise. After the knob is fully backed off, open the valve up 6 to 7 full turns
clockwise. This will bring the internal air pressure to approximately 85 PSI.

ƒ Push-click the knob back down.

ƒ Test cut a few pockets. Remember, too much or too little air pressure can effect your
tooling. You will want to make sure the setting of the internal regulator does not go
above 85 PSI and the cycle time on the machine should be 1 to 1 ½ seconds. Adjust the
regulator and flow control as necessary to get these settings.
