Intended use

The drill stand is intended for holding diamond drills
with a maximum power of 2.2 kW in conjunction
with wet diamond drill bits and a water supply for
wet drilling in mineral materials such as concrete,
reinforced concrete or masonry. The largest
allowable diameter drilled is 200 mm for the
BST 200 and 250 mm for the BST 250. Other units,
which exceed these values, may not be used. The
drill stand can be attached to the floor and to the
wall with the help of plugs / anchors or vacuum.
NOTE
Use RAWL anchors with diameter 20 mm / M12 for
fixing onto walls.
Observe the relevant regulations in your
country for the materials to be machined and
extraction.

Before starting work

To ensure safe working with the drill stand, the
following points must be observed before each use:
•
Read through all safety instructions and hazard
information in this instruction manual and in the
instruction manual of the drive unit / drill used.

the drill stand.
•
2 / 3 Mounting the feed crank handle:
f
2 Push the feed crank handle (3), as
required, to the left or right onto the pinion
shaft (4) so that the drillhole in the feed
crank handle (2) and in the pinion shaft (1)
coincide.
f
3 Push the pin of the tube lock (1) through
the matching holes (2) and push until the clip
is snapped into position.

Operation and Control

The drill stand can be fixed onto the floor or wall
using a retaining screw.
5.1 Installing the drill rig with plug
fixing
5 Use the diamond core drill bit to align the drill
stand with the hole to be drilled:
•
5 Mark the plug hole for fixing the drill stand
plate (5) through the mounting slot and drill (drill
hole: Ø 15 mm, depth 50 mm).
•
6 Insert the retaining screw (1) with attached
quick-action plug (2) in the plug hole.
•
5 Align the drill stand plate (5) with the help
of the spirit level (6) and the four adjustable
feet (4).
•
5 Screw in the retaining screw (3) with the help
of the spike (2).
•
5 Tighten the quick-action nut (1) with light
hammer blows.
5.2

Fixing onto the wall

NOTE
Use RAWL anchors with diameter 20 mm / M12 for
fixing onto walls.
1 If fixing onto the wall, an external spirit level
must be used to adjust the perpendicularity of the
drill stand with the drillhole of the diamond drill
core bit. This adjustment cannot be made using the
integrated spirit level (7) on the drill stand.
5.3 Installing the drill stand with
vacuum kit (accessory)
If it is not possible to install the drill stand with the
anchor fixing, the drill stand can be fixed to the floor
or wall using a vacuum kit (order on request). The
installation of the vacuum kit is described in the
relevant installation instructions.
