Safety regulations
❖Read all precautions before start-up and keep the operating instructions.
❖Please follow the operating instructions carefully, as failure to follow these
safety precautions and instructions may cause electric shock, fire and/or
serious injury.
1. Keep your work area clean and well lit. Disorder or unlit work areas can lead to
accidents.
2. Do not work with power tools, near flammable liquids, gases or dust. Power
tools produce sparks that can ignite dust or fumes, causing explosions.
3. Keep children and other persons away from tools during use. If you become
distracted, you may lose control of the tool.
4. Be attentive, work with concentration and pay attention to what you are doing.
Do not use a power tool when you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention can result in serious injury.
5. Wear suitable protective equipment and always protective goggles. Wearing
suitable protective equipment such as dust mask, non-slip safety shoes,
gloves, hard hat or hearing protection reduces the risk of injury.
4
6. Avoid unusual postures. Ensure a secure footing and maintain your balance at
all times. Do not work on a ladder. This will give you better control of the power
tool in unexpected situations.
7. Wear appropriate clothing. Do not wear loose clothing or jewelry. Keep hair,
clothing and gloves away from moving parts. Loose clothing, jewelry or long
hair can be caught by moving parts.
8. The use of products such as cutters, grinders, drills that machine sand or
materials can generate dust and fumes that may contain hazardous chemicals.
Check the type of material you are going to machine and use a suitable
respirator.
9. Never work alone, always make sure that another person is nearby. Apart from
the fact that you can get help with the assembly of the drill, you can also get
help if an accident should happen.
10. Never use a drilling instrument that is faulty. Carry out the maintenance and
service instructions described in this manual. Some maintenance and service
measures must be performed by trained and qualified personnel.
11. Before mounting the drill motor and drill bit, make sure that the stand is
properly secured.
12. The drill stand must be fixed on a level and firm surface. Drilling with a loose
and/or wobbling stand can lead to a dangerous situation.
13. The core drill rig is intended for the intended purpose, the mounting of the drill
motor for stationary drilling. All other uses that are not for the intended purpose
are prohibited.
5
14. Always use compatible drilling tools with the drill stand. The connection to the
core drilling motors must be in accordance with the stand.
15. When used for overhead drilling, a functional water collection ring must be
used. Make sure that no water can get into the motor.
16. Check all moving and clamped parts before use.
17. Only use original spare parts from Kernlochbohrer GmbH.

Mounting the drill stand
Determine the desired position of the stand. Then
fasten the stand with a concrete anchor. To do this, drill
a hole of suitable size for the anchor using a hammer
drill.
When anchoring to a brick wall, a special masonry anchor and brick fixing kit must
be used. The use of a concrete impact anchor in brick could lead to brick
breakage and loosening of the anchor!
If you use our vacuum base plate VGP-420/PRO to fix the core drill rig, make sure
that the vacuum is at least -0.8bar and make sure that the seal is not worn or
damaged.
7
Warning!
In the case of overhead drilling, vacuum attachment to the ceiling is prohibited as
it can cause serious injury.
To bring the drill stand into
the correct position, use the
four leveling screws and the
level indicator attached to
the drill carriage for this
purpose. Then tighten the
lock nuts on the leveling
screws. The entire stand
must be firmly mounted.
Adjust the angle of the drill stand to the position using
the drill center of the desired drill hole. The adjustable
drilling angle ranges from 0 ° to 45 °. If you need to drill
at 45 °, loosen the clamping screw with the attachable
13mm crank.
Loosen the clamping screw on the column support and set the angle according to
the scale on the drill column. Once the angle is set, tighten the clamping screw
again. Make sure that the mounting adapter and the carriage are fixed.
Note!
Do not overtighten the clamping screw, otherwise the column support and the
bracket may deform.
8
Check if the guide on the column is loose. If it is loose, you must adjust the 4
eccentric clamps inside the drill carriage. Use a 13mm wrench and an 8mm
wrench to tighten the clamping nut for adjustment. Now test the proper fit of the
drill slide by cranking it up and down. There should be no play, but also no
jamming throughout the travel.
The KBS-352/M-PRO/KBS-352/XL-PRO and KBS-502/
M-PRO each have a different mounting adapter. The
mounting adapter of the KBS-352/M-PRO and KBS-352/
XL-PRO is 60mm while the mounting adapter for the
KBS-502/M-PRO is 110mm to allow drilling with larger
diameter drills.
Before mounting the drill motor
on the stand, first set the drill
slide to a higher position to
make it easier to mount the
adapter plate.
When mounting a drill rig of the DKB-PRO series to the core drill rig KBS-352/M-
PRO, KBS-502/M-PRO, KBS-352/XL-PRO, you first need 4 screws to fix the
mounting adapter to the motor. There is a 10x10x100mm keyway on the
mounting adapter, which absorbs the torque of the motor via the key. Now adjust
the locking screw so that the fastening adapter can be inserted effortlessly. Now
place the fastening adapter with the dovetail in the guide. Tighten the locking
screw until the plate is secured in the guide. To be able to remove the drill motor
again, loosen the fastening screw completely.
9
The locking device of the drill
carriage is located on the top
side of the drill carriage. It is
intended to prevent the drill
sled from falling down and
causing possible injury or
damage to the drill or the
machine.
Slide the carriage lock to the left to unlock the carriage, then crank the drill
carriage up or down to the desired position and slide the lever lock to the right to
lock the drill carriage. After making the desired adjustments, such as inserting the
motor, unlock the locking device and tighten the thumbscrew on the lever lock to
begin operation.
Note!
Do not crank the carriage up and down when the lever lock is in the locked
position, as this will damage both the rack and the lever lock.
For easy removal of the drill, use the quick-change ring
which is placed on the drill shaft in front of the drill bit.
The cup wing nut of the cord threaded rod (in the
optional fastening set) is a large wing-shaped nut with
washer. It can be used together with an impact anchor
to fasten the drill stand to the substrate.
