Performing Pressure Tests
This is a governed air motor, and air flow usually increases as the load
increases.
A variable speed drill motor will use more air at higher speed settings.
For all tests on the following pages, screw the 1/2 inch pipe nipple and
tee directly into the inlet bushing of the air tool. Do not use a quick
disconnect fitting between the tee and the inlet bushing (see diagram).
The 1/8 inch tee need not be installed at this time.
Adequate Air Supply
This includes valves, hoses, couplings, supply pressure, etc. Normally
this test would be performed at the drilling site with the length of hoses
and couplings in use.
Attach the air hose or the large quick disconnect coupling to the 1/2 inch
tee. Plug the air guage into the fitting on the tee. Rapid advance the tool
and read the guage pressure before and during rapid advance.

See Appendix I for unusual conditions.
The following tests should be done in the tool crib or repair-maintenance
area.
NOTE: Remove the tool nose and spindle.
Air control system (A.C.S.) pressure checks. The 1/8 inch tee should
also be installed at this time (see diagram).
Feed piston pressure —plug air guage into the A.C.S. Start motor with
the drill button. The tool automatically goes into feed with the motor
running. The A.C.S. pressure must be over 60 psig.
