Page 10: Precautions
Precautions 1. ALWAYS wear hearing protection! When using drill motors, the loud drilling noise in the working area can cause hearing damage. 2. When drilling, keep a sufficient distance from the core drill and do not touch any rotating parts. Protect the danger zone and keep children and other persons away from it. -
Page 11: Operation On Drill Rig
Operation on drill rig All DKB/H series drills are designed for use with a drill stand. Only place the machine in a stable drill stand with precise guides. Make sure that the machine axis is parallel to the drill stand column. Only use drill stands with sufficient stability. -
Page 12: Cooling Of Drill And Machine
For easier removal of the core bit, you can apply waterproof grease to the spindle thread of the machine. To mount a drill bit on the core drill, simply screw it onto the drill spindle. With the help of a copper ring (not included in the accessories) you can loosen the core bit more easily. -
Page 13: Electrical Connection
Electrical connection To reduce the risk of electric shock and to protect the operator, the core drill rig DKB-132/2H must only be operated via a Portable Residual Current Device, or PRCD personal circuit breaker. After connecting to the power supply, first press the "RESET"... -
Page 14: Water Supply Connection
Water supply connection If the core bit is not cooled sufficiently with water, the diamond segments can heat up, which damages them and considerably reduces the service life of the core bit. Therefore, you should always make sure that a steady water supply is ensured. To connect the water supply, attach the quick coupling to a water hose. -
Page 15: Drilling
Turn the transmission switch to the faster or slower gear until it engages. Only change the speed when the machine is at a standstill. If necessary, support the shifting process by slightly turning the work spindle. If the machine stalls due to the hardness of the material, select a lower gear to protect the machine from overload. - Page 16 Increase the feed pressure as soon as the cutting depth reaches approx. 10mm. Always keep an eye on the condition of the drill motor. If you notice that it starts to smoke slightly or if you notice the smell of an electric motor, relieve the core drill by withdrawing it from the core hole.

Page 17: Electronic Overload Protection
Electronic overload protection The DKB-132/2H is equipped with electronic overload protection. If the core drill is in an overload state for a long time, the machine switches off for its own protection. Disconnect the machine from the power supply. Carry out a visual inspection of the machine. -
Page 18: Shutdown Carbons
Shutdown carbons The power tool is equipped with a self-shutting carbon brush to protect the motor. If the brushes are worn, the machine switches off automatically. In this case, both carbon brushes must be replaced at the same time by original carbon brushes from our shop by a trained electrician according to VDE. -
Page 19: Daily Maintenance Of The Power Tool
Remove the drill core if it remains in the drill bit: 1. Disconnect the core bit from the core drill (if possible). 2. Set the drill bit vertically. 3. Tap lightly against the core drill cylinder with a wooden hammer handle or a rubber mallet until the drill core slips out. -
Page 20: Behaviour In The Event Of Disruptions
After approx. 300 hours of operation, the carbon brushes must be checked by a trained electrician according to VDE and replaced if necessary (only use original carbon brushes from our shop). If cooling water leaks uncontrollably from the oil seal, have it replaced by a specialist workshop and only use original spare parts from our shop. -

Page 22: Environmental Protection
Environmental protection Raw material recovery instead of waste disposal! To avoid transport damage, the unit must be delivered in sturdy packaging. Packaging as well as the unit and accessories are made of recyclable materials. The plastic parts of the unit are labelled according to the material. This enables environmentally friendly, sorted disposal via the collection facilities offered. -
Page 23: Warranty
For an accurate estimation of vibration exposure, the times when the unit is switched off or running but not actually in use should also be taken into account. This can significantly reduce the vibration exposure over the entire working period. Establish additional safety measures to protect the operator from the effects of vibration, such as: Maintenance of power tool and insert tools, keeping hands warm, organisation of work procedures. -
