(1.1) on the base board or with the scale on the
parallel guide.
 The parallel guide is then tightened in the re-
quired position by means of the clamping screw
(2.1).
 With the tilting version, the ruler can be ad-
justed in the vertical direction (2.2) as well.
6.7 Adjustment of the angle of inclination
(GD 460 A)
The tilting drilling stands (GD 460 A) allow for
oblique drilling at the angles ranging from 90° to
45°. In perpendicular drilling, the indicator (18)
on the scale (17) reads zero.
 Before the eventual adjustment of the angle of
inclination, both the clamping nuts (16) are to
be loosened.
 Now it is possible to tilt the guide bars to the
required angle.
 This angle can be ascertained on the scale (17)
with an accurate division.
 The indicator (18) is set to the required value
of the scale, and then both the clamping nuts
(16) are tightened again.
CAUTION: With the tilted drilling stand,
the base board must be secured against
sliding along the workpiece, because of
safety reasons. The employment of the
clamping elements (accessory) is an ide-
al way of fastening it.
6.8 Correction of the stop position (GD 460
A)
With the tilting drilling stands, the perpendicular
position has been adjusted in the manufacturing
plant by means of the stop screw (14).
If an additional adjustment of the set stop position
is required, proceed in the following way:
 Loosen the securing nut (14.1) and the clamp-
ing nut (16).
 Bring the foot (15) to rest upon the head of the
screw (14).
 Turning the stop screw in the required direc-
tion, you will change the angle to the required
position.
 Tighten the securing nut (14.1) and the clamp-
ing nuts (16) again.
 The indicator (18) can also be reset after haying
loosened the screw (19), and screwing it tightly
again in the required position.
6.9 Clamping of the drilling stand
For the clamping of the stand upon the material,
there serve the clamping elements (12). These
can be fastened upon the base board (1).
 Insert the clamping element into the orifi ce
(1.4) from below, screw the clamping nut (12.1)
upon it from above, and tighten it.
 By means of the screw (12.2), tighten it in the
required position.
The clamping elements (not included in the scope
of the delivery but accessories) are used always
in pairs, from both the sides. We recommend em-
ploying four clamping elements.
For materials up to the maximum dimension of
300 mm, the clamping elements can be fastened
on the bracket (13).
 Fit the screws (13.1) from below into the ori-
fi ces in the base (1.4).
 Set the brackets upon the screws (13.1) from
above, and tighten them with nuts (13.2).
The brackets (which are not included in the scope
of the delivery, accessories) are offered in pairs
(2 pcs). It is necessary to pay attention to the stand
to be clamped on the beam between two clamps
(12), situated on one bracket (the distribution of
forces in the longitudinal sense of the bracket),
not by means of two brackets (see the fi gure). The
brackets have been designed in such a way that
it might be possible to clamp them upon both the
basic types of the stands (the vertical ones and
the tilting ones) both in the longitudinal and the
vertical directions.
7 Drilling
- Before you proceed to drilling, make sure that
both the spiral drill and the drilling machine
are well clamped.
- Check the stops and the guide disk, to see,
whether they are set tightly, and if necessary,
tighten the clamping elements.
- Do not work with blunt of damaged drills.
- During the drilling operation, hold the equip-
ment always with both hands: one hand on the
additional handle of the drilling stand, and the
other hand on the handle and the switch of the
drilling machine.
- The marking on the base board (1.2 and 1.3)
serves for drilling with visual control according
to the mark.
7.1 Guiding disk
For the spiral drills with even diameters, there
is employed a guide disk which is included in the
scope of the delivery. For the spiral drills with odd
diameters, there is employed a guide disk with
odd diameters, supplied as an accessory.
 For the replacement of the guide disk, unscrew
the rotary button (3.1).
 Next, it is possible to remove the installed guide
