Rotate the feed tube counterclockwise until 3
additional threads are exposed. (This ensures the
pilot drill is not on the pipe and is in the proper
position to start drilling.)
Place air motor on drilling rod square.
Operator should ensure the air compressor is
working properly at 90 psi measured at the inlet of
the air motor.
Refer to manufacturer air motor specifications
guide.
Make certain the oiler / separator is in place.
NOTE: If issues with air motor occur, tapping can
be completed by hand using the ratchet.
Use the air motor to turn the drilling rod
clockwise.
While the drilling rod is rotating clockwise slowly
hand feed the cutter downward by turning the feed
tube handles clockwise to cut the pipe.
(Do not feed the cutter too quickly and cause a
bind and potential cutter breakage. Especially on
steel and cast iron.)
The tapping procedure is finished when the
drilling rod can rotate without any resistance or
the maximum drilling depth mark is reached.
NOTE: You will feel less resistance twice - once
in the beginning when the pilot drill has perforated
the pipe wall and secondly when the cutter is
completely through.
