The KS30 is a drill rig which is meant for fixing WEKA diamond core drills type DK26, DK32, SR2 and
SR38. The diamond drill rig can be fixed to the ground and to the wall by means of dowels, vacuum or
quick bracing columns.
The core drillexists of a eletric motor with step-down gear. Via the quick connect nipple water is supplied
directly to the drilling tool (diamond core bit). Thus the cutted material is flushed away and the tool is
cooled (wet drilling).
The drilling tool (diamond core bit) is a hollow drill (tube) which is fitted with soldered-on or welded-on
segments impregnated with diamonds.
In the wet use, if necessary, the flushing water is extracted through a water collecting ring by means of
an all-purpose suction unit.
Avoid wet drilling upwards (overhead drilling) (Überkopfbohrungen). If it is indispensable
use a proper working water collecting ring.

5. P R E P A R A T I O N
Make sure that the drill rig has not been damaged during transport. Check if all components are at hand.
Screw the 3 handles of the hand wheel (20) into the shaft center up to marking.
Lock for all works on the rig, in working breaks and while not on use, the feed. Therefore clamp the fixing
brake (19). For drilling loosen the fixing brake (19) so far, that the hand wheel can be moved easily. Hold
the hand wheel, for avoiding an uncontrolled down sliding of the drilling machine.
5.1 Assembling the diamond core drill (see images A and B)
Feed slide (16) and quick connect plate (13) can only be connected in one position with each other (see
image B). The feed slide has a shape, the machine reception of the feed slide a corresponding cut-out.
Put the quick connect plate (13) on the core drill in that way, that the parallel keys (12) engage into the
corresponding cut-out of the gear foot of the core drill. Screw the quick connect plate and the core drill
together with the four hexagon socket screws (11) which are included in delivery.
Loosen the eccentric bolt (14) with the hand wheel (20) and pull it out of the feed slide (16) as far as it will
go. Hang the drilling machine with the quick connect plate (13) into the machine reception in that way,
that the lower nose of the quick connect plate is behind the lower bolt of the machine reception (see
image A).
Clap the drilling machine onto the machine reception and put the eccentric bolt (14) back in. Tighten the
eccentric bolt (14) with the hand wheel (20) (the eccentric bolt clamps clockwise as well as anti-
clockwise).
For loosening the core drill proceed the other way round.
For the WEKA diamond core drill SR25 there is alternatively a quick connect plate available with part no.
KS30745.2. When using this quick connect plate holes of 300mm up to 350mm diameter can be drilled
without an additional distance plate.
5.2 Distance plate for holes 300 - 350 mm (see image C)
For holes of 300 mm to maximum 350 mm diameter the distance plate (31) must be inserted additionally
on the WEKA drill types DK26 and DK32. Therefore put the quick connect plate (13) in that way on the
distance plate (31) that the parallel keys (12) of the quick connect plate engage into the corresponding
channels on the distance plate. Then put the distance plate (31)including quick connect plate (13) on the
core drill in that way, that the parallel keys of the distance plate engage into the channels of the core drill.
Insert the four screws (32) of the distance plate and tighten these with a hexagon socket wrench. Then
mount the drilling machine and described above on the drill rig.
5.3 Fixing the drill rig
The drill rig can depending on the surface of the underground be fixed with dowels, vacuum or a quick
bracing column.
5.3.1 Fixing with dowels
Use only suitable steel dowels, resp. anchors with a drilling diameter of at least 16 mm and a thread bars
of at least M12. Therefore consider the requirements of VDMA. Take care that the dowel is absolutely
tight and the required tear out force are not exceeded.
Insert a concrete dowel with expansion key (27) resp. a masonry dowel. Screw the quick clamping spindle
(28) into the dowel. Put the machine as well as a washer (29) on and screw these on with the split nut
(30).

10
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
When 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.
When drillinginclined, in thestart of drillingphase a lowerdrilling pressure has to be chosen,foravoiding
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). With 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.
6. P U T T I N G I N T O O P E R A T I O N
6.1 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.

6.2 Water collecting ring
For collecting the water which escapes from the drill hole when drilling wet, you need a water collecting
ring (21) and an all-purpose suction unit.
Push the tension spring (24) as far as it will go into the gap between rig foot (1) and rig column (4). Take
care that the angled part of the tension spring points downwards. Bring the water collecting ring (21) into
position and put the tension spring onto the supporting point at the water collecting ring. (The links at the
ends of the tension spring are required for pulling the spring upwards.) By the tension force of the spring
the water collecting ring with its sealing is pushed to the underground and together with the vacuum of the
wet/dry suction unit avoids the water outlet.
The water collecting ring can be turned within its tension ring, for bring the connecting piece into the
desired position. Therefore open the fastening of the tension ring at the water collecting ring, turn the
water collecting ring as required and close the fastening again.
6.3 Drilling
When the drill rig if necessary with water collecting ring is fixed absolutley safe and rigid and is adjusted,
open the water valve so that enough water for cooling and flushing is available. Choose the gear on the
core drill which is most suitable for your drilling diameter and switch the machine on.
Choose the position of the hand wheel (20) which is most suitable for you (left or right).
Start drilling by turning the feed wheel at the drill rig carefully. Thereby take care that the core bit does
neithervibrate or shake heavily. When the core bit has centered itself after approx. 1 - 2 cm drilling depth,
the feed force can be increased until the optimal feed power is reached, however only to the maximum
power of the machine.
When you drill reinforcement you have to increase the feed force if necessary for ensuring an appropriate
feed. Often it makes sense to change the gear on the machine to a lower speed.
Ensure that you do not drill into or through a water pipe or even an electric mains. In case
of doubt you should on principle check your drilling area with a line detector.
When drilling with vacuum fixture the feed power may only be so high that the drill rig
does not tilt over and thus loosen the vacuum. When the drill rig begins to tilt, the feed
power must be reduced immediately.
6.4 General directions for drilling
Adjust the water quantity at the ball valve when drilling wet so that the cutted material is flushed from the
drill hole completely.
You do not wash out enough material if mud occurs around the drilled hole.
Use sufficient contact pressure. If it is too low the diamonds tend to polish. This means that the feed
speed becomes less until finally no material is cleared away any more.
In this case the segments are to "sharpen" again by means of a SiC-grindstone.
Take care that the core bit does not vibrate, otherwise the diamonds are detached by force from the core
bit.
In case the tools gets stuck, do not try to loosen it by switching the machine on and off. Immediately
switch off the machine and loosen the bit by turning an appropriate wrench to the left and right. At the
same time, pull the machine out of the drilled hole carefully.
7. M A I N T E N A N C E
Clean the machine after finishing the drilling. Thereby also clean the thread of the tool fixture and grease
it.
Oil the threads of the lackscrews and the bearings of the feed and clamp shaft regularly.
Keep the toothed rack and the bearing surface of the column always clean.
7.1 Adjusting the guide slide bearings
For achieving good drilling results, the clearance between feed slide (16)and rig column (4) has to be as
low as possible.
Over the time the guide rolls may wear out and clearance can occur between the guide rolls and the rig
column. For eliminating this clearance both guide rolls must be readjusted on the side of the fixing brake
(19). Loosen both hexagon nuts (33) with a socket wrench (wrench size 17mm).

Then tighten both hexagon sockets screws (34) equally until the clearance is minimized. Retighten the
hexagon nuts (33), while holding up the hexagon socket screws at the same time.
