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, S.L.
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
33
). 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 33
),
turn slightly in the opposite direction to return to the
previously-recommended distance.
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.

Disassembly of the machine and accessories:
Once the mains has been perforated, move the chuckshaft up by
turning the machine body counterclockwise.
Disassemble the saddle adapter and drilling machine using the
spanner designed for this purpose.
The coupon resulting from drilling the mains will have remained
trapped by the pilot drill’s coupon retainer mechanism. To
extract the coupon, disassemble the drill by loosening the Allen
fastening stud. Remove the coupon through the upper part of
the drill and fit it to the arbor hole saw again. See
Figure 34
.
WARNING !
Do not touch the coupon following drilling,
especially if an electrical or pneumatic swivel
gear has been used. Hot surfaces.
