Commissioning
Check that the mains voltage is identical to the voltage specified on the model plate.
Stand-mounted:
Secure the machine and the water collection device on the drill stand with a reverse lock. The drill stand should
have high rigidity and precise, low-play guides. Ensure that the machine axis is parallel to the drill stand axis.
Insert the core bit and set the speed. Setting instructions are given in
chapter 8.
Connect the water supply. Important:
Do not exceed the max. water pressure of 3 bar.
Both voltage versions of FB 20 P (110V and 230V) are equipped with a PRCD-safety switch in the cable, so the
FB 20 P can be directly connected to the main supply.
Manually controlled:
When drilling a hole ensure that you are on a secure surface. Make particularly sure the core bit is not bent
during the drilling process and hold the core drilling machine as rigid as possible. Concentrate hard on the work
since if the core bit suddenly blocks, despite the low setting of the safety slip clutch, high forces may be
generated. If you let go of the core drilling during the drilling process, you may suffer serious injury.
Only used three-core extension cables with a protective conductor and an adequate cross-section. If the cross-
section is too low you may suffer excessive power loss and the motor and cable may overheat. An extension
cable must be secured with an overload switch. Recommended cable cross-sections:

When drilling a hole ensure that you have sufficient cooling water. Only use clean tap water, do not use dirty or
waste water. Adjust the supply to the core bit diameter and drive rating of the core drill so that you do not exceed
the rated current.
5.1 Changing gear
Move the gear switch handle by approx. 40° to the next higher or lower gear. If necessary (if it is difficult to
engage the gear) turn the drive spindle briefly by hand until the gear engages easily. Never use tools (pliers,
hammer, etc.) to change gear since otherwise gear damage will be inevitable.
5.2 Safety coupling
The values set out in the table are theoretical values and may be used to provide a rough guide for gear
changing. Since a whole range of other parameters also plays a major role in adjusting the speed, we cannot
offer any guarantee if the tool is damaged when using the values in the table. Drilling work for which the speeds
are outside the range of the core drill (values printed in italics), should only be completed with extreme care and
by trained personnel.
Never change gear using force and only do so when the machine is slowing down or at a
standstill.
