Check that the mains voltage is identical to the voltage specified on the model plate.
Secure the core drill and the water collector to the drilling stand with its reverse block. The drilling stand
should be as rigid as possible and have precise, low-play guides. Ensure that the core drill axis is parallel
to the axis of the drilling stand.
Insert the core bit and set the speed. The setting instructions are on page 12.
Connect the water supply. Important: Do not exceed the maximum water pressure of 3 bar.
Connect the core drill to the mains using a residual current-operated circuit-breaker box and 1 h coded plug
or a PRCD safety switch. Only use three-core extension cables with a protective conductor and an ade-
quate cross-section. If the cross-section is too low, you may lose excessive power and result in the motor
and cable overheating. An extension cable must have an overload cut-out switch. Recommended cable
cross-sections:

Ensure that you have sufficient cooling water for drilling. Only use pure tap water, do not use dirty or waste
water. Adjust the feed speed to the core bit diameter and the drive rating of the core drill so that the rated
current is not exceeded.
