Drilling the mains:
Once the pressure test is complete, 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
9
). 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.
SWIVEL GEAR
If an electrical actuation swivel gear (drilling machine) or pneumatic
swivel gear (pneumatic, non-impact tool) is used, the following
considerations must be taken into account:
C
The rotation speed must be that indicated by the hole saw
manufacturer.
C
The adapter components may be supplied by Acuster Global, SL.
C
The usage and safety recommendations given by the manufacturer
must be followed.
The feed is achieved by making the machine body rotate
(with the hand placed in the knurled area). The
recommended distance produced by the feed is
a
= 1 or 2
mm (see
Figure 9
) when drilling with the pilot drill. Once
perforated with the drill, remember that distance
a
will be
increased by the internal driving pressure. The feed limit is
indicated by a mechanized line on the fastening bush shaft.
If due to an excess of compression (feed + internal
pressure) this line becomes visible (see
Figure 9
), turn
slightly in the opposite direction to return to the previously-
recommended distance.
Ensure that the drilling is complete by making one or two
additional turns.

WARNING !
It is recommended to avoid excess feed, especially in the pilot drill work
phase, given that the drill could break specially at low revolutions.
