Castle TSM-21

Air Pressure Regulator, Setting

21.90

The Pressure Regulator determines Drill Feed Rate, clamping pressure, and overall speed of the
machine. The factory setting is approximately 75 PSI. and should be checked periodically or when
machine performance becomes rough or too slow. Cycles that are too slow can burn bits and cause drill
bit separation at the shank. Cycles that are too fast can cause drill bits to break or to cut over-sized
holes.

NOTE: It’s extremely important that a minimum 85 PSI be provided from your compressor. Operating
pressure can be especially affected by other machines that share the same air line as your TSM-21.
