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 cou-
plings 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.
