Drilling the mains:
Once the machine set and saddle accessories are assembled, lower the chuckshaft by
rotating the machine body (with your hand in the knurled area), until the pilot drill makes
contact with the pipe (the chuckshaft will have risen depending on the contact force: see
measurement
a
of
Figure 33
). At this point, withdraw the tip of the drill from the pipe by
approximately one turn.
Now begin drilling the mains by activating the chuckshaft using the ratchet wrench, if
drilling is manual, or through the electrical or pneumatic swivel gear.
