Warning of general danger. Failure to comply with these safety precautions and
instructions may result in electric shock, fire and/or serious injury.

Safety regulations
❖Read all precautions before commissioning and keep the operating instructions.
❖Please follow the operating instructions carefully, as failure to observe 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 people away from tools while using them. If you are
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
medicines. A moment of inattention can lead to 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.
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.
4

8. The use of products such as cutters, grinders, drills that machine sand or other
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 serves the intended purpose of mounting the drill motor for stationary
drilling. All other uses not intended for the intended purpose are prohibited.
14. Always use compatible drilling tools with the drill stand. The connection on the power
tools 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
Fixing is possible with the help of anchor bolts or metal dowel M14 with threaded rod.
Determine the desired position of the stand. Then fix the stand with a metal anchor and a
threaded rod or a suitable fixing set. To do this, drill a hole of suitable size for the anchor
using a hammer drill.
If anchoring to a brick wall, a special masonry anchor and brick fastening kit must be used.
Using a concrete drive-in anchor in brick could result in brick breakage and loosening of
the anchor!
To bring the drill rig into the correct position, use the four leveling screws and the bubble
level 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 based on 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 on the column support and adjust the angle 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.
The lower clamping screw should be adjusted so that the angle can be changed easily. If
you notice that the drill column has too much play in the lower area, tighten it slightly with a
19 mm wrench and the hand crank.
Note!
Do not overtighten the clamping screw, otherwise the column support and the bracket may
deform.
The KBS-200M has a 60 mm clamping bracket which is pre-mounted on an adapter plate.
Before you attach the core drill to the column support, first set the drill slide to a higher
position to make it easier to insert the core drill.

In order to be able to fix the drill carriage to the drill column, there is a locking device on
the side of the drill carriage. It is intended to prevent the drill carriage from falling down
and causing possible injuries or damage to the drill or the machine.
Turn the carriage lock to the left to unlock the carriage, then crank the drill carriage up or
down to the desired position and turn the carriage lock to the right to lock the drill carriage.
After you have made the desired adjustments, such as inserting the core drill, unlock the
locking device to start operation.
Note!
Do not crank the carriage up and down when the carriage lock is in the locked position, as
this will damage both the rack and the carriage lock.
For easy removal of the drill, use a copper ring which is placed on the drill shaft in front of
the drill bit.
If you are drilling a wall with a stand, first secure the stand to the wall, then mount the core
drill on the stand.
Care and maintenance
Repairs may only be carried out by qualified personnel suitable on the basis of their
training and experience. The core drill rig is designed to require a minimum of care and
maintenance. However, the following point must always be observed:
• After completing the drilling work, clean the core drill rig from dirt and dust and, if
necessary, grease the rig for easier operation.
• After finishing work with the stand, grease the shafts and their threads. Make sure that
no water runs out of the carriage and there is no dust buildup on the carriage.
8

• If possible, do not use water to clean the drill stand, as some metal parts can
accumulate flash rust and this can lead to malfunction. Make sure that the drill stand is
dry after use and cleaning.
• In the rear area of the drill slide there are 4 rollers. There are also 2 eccentric clamps in
the rear area. In the course of time, wear may occur on the rollers. If this is the case,
adjust the 2 eccentric clamps on the rear of the core drill rig slightly until the slide can be
moved again without play. The eccentric clamps (silver colored) are located on the left
side. If it is no longer possible to readjust the eccentric clamps, all 4 rollers must be
replaced to prevent further damage to the gear shafts and the rack.
• Always pay attention to the wear listed above. Replace the rollers and/or the eccentric
clamps if necessary. If the problem persists, replace the drill column.
• Check the stability of the drill stand before each use. If the base plate of the drill stand is
damaged, replace it before using the drill stand.
•
• Periodically perform a visual and functional check to ensure that all terminals and
moving parts are fully functional.
• Only use the drill stand up to the maximum permissible diameter. This can be found on
the type plate of the respective stand.
• Failure to comply with this specification may result in malfunction during operation of the
drill stand as well as injury to the operator.
