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
18
). 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 18
),
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 main 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 19
.
WARNING !
Do not touch the coupon following drilling,
especially if an electrical or pneumatic swivel gear
has been used. Hot surfaces.

connection fasteners.
