Check that the mains voltage is identical with the voltage specified on the model plate.
Stand-mounted:
Secure the core drilling 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 core drilling machine axis
is parallel to the drill stand axis.
Insert the core bit and set the speed. Setting instructions are given on page 12.
Connect the water supply. Important: Do not exceed the max. water pressure of 3 bar.
Connect the core drilling machine to the mains via an RCCB box and a code plug 1 h or a PRCD safety
switch.
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.
