Always put the dowel as near as possible to the drill column. Adjust the drill rig by means of the attached
water levels (9, 17) before you tighten it via the dowels.
5.3.2
Fixing with vacuum
For fixing the drill rig with vacuum, you need a KS30 vacuum kit (25, 26) and a vacuum pump with a
throughput of at least 6 m²/h and a vacuum of at least 80% (-800mbar).
Take care that the drill rig is solidly fixed. Turn the jackscrews (3) at the rig foot against the fixing surface
until the sealing ring is released slightly (optimum 5-8mm).
On vacuum fixtures you have to take care, that the undergournd surface is not too rough and not porous.
Attention: Vacuum fixing is not suitable on plaster or masonry. Never drill overhead with
vacuum fixing. Horizontal holes at the wall only with an additional securing.
Before using the vacuum kit, check the vacuum adaptor (25) and the sealing ring (26) on wear. Fix the
vacuum adaptor (25) by inserting and turning in the slot of the rig foot (1).
5.3.3
Fixing with quick bracing column
The drill rig can be fixed (braced) with a quick bracing column between rig foot and wall or ceiling. Only
use suitable bracing columns.
5.4
Working positions
W hen working on floor areas of stories, the core can fall into the lower story when drilling through and
cuase serious injuries and damages. Ensure that noboby remains under the drilling area. Protect this
area.
Before drilling in walls, you have to make sure that when drilling through, nobody can be injured.
Overhead drillings can only be made with suitable water collecting devices. Protect the drill rig
additionally.
W hen drilling inclined, in the start of drilling phase a lower drilling pressure has to be chosen, for avoiding
that the drill bit runs uneven.
5.5
Diamond core bit
Only use suitable high-quality diamond tools.
Ensure that the diamond segments are sufficiently larger than the inner and outer diameter of the drill bit
tube.
Apply water-resistant grease to the tool thread so that the tool can be easily loosened.
Ensure that the radial run out at the diamond segments of the drill bit is no greater than 1 mm
(eccentricity).
Only use suitable wrenches for changing the core bit. Therefore put the wrench (only KS30 and KS30S)
with which you fix the drill bit at the stop bolt (35). W ith a second wrench now loosen the drill bit of the drill
spindle.
Never use a hammer or something similar to open the core bit. If necessary elongate the
wrench.
5.6
Electrical connection of the drilling machine
Therefore please consider the relevant regulations of the manufacturer.

Adjusting the drilling angle
Remove the cap nut (7) with the hand wheel (20). Adjust the drill stand by means of the drill angle scale
(8) to the desired drilling angle. Tighten the cap nut (7) with the hand wheel (20) hand-tight.
Attention: The drill rig may only be put into operation when the cap nut are again
tightened.
