5.26 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.
