Drilling
Preparation
!
When drilling into blocks make sure that they are well fixed and fas-
tened.
!
Before drilling into load bearing elements make sure that the founda-
tions are not damaged. Follow the instructions of the specialists respon-
sible for planning.
!
Make sure not to damage any water or gas pipes or power lines during
drilling.
!
Make sure not to touch any metal parts of the tool when drilling in walls
or floors, where power lines might be lying in water.
!
Make sure that the drill core will not hurt anybody or cause damage to
anything when falling out. Clear and secure the work area.
!
When drilling through holes through ceilings, secure the area from be-
low, as the drill core may drop downwards.
!
If the drill core could cause damage when dropping down, set up a cor-
doned off area.
!
Make sure that the drill bit is fixed correctly.
!
Use the correct tools appropriate for the material to be worked upon.
Execution of drilling
!
Check PRCD for correct function.
!
Open the water supply.
!
Switch the motor to ON, the drill bit must not yet touch the surface.
!
Lower the drill bit until it touches the surface.
!
In order to achieve an exact centering of the drill bit, minimize the for-
ward travel of the drill bit during the first centimetre of cutting depth.
!
Now you may increase the drilling speed. If the speed is too low, the
performance of the tool is impaired. If the speed is too high, the dia-
mond segments will become blunt in a short time.

! Remove the bolt, which holds the support at a 90° an-
gle, from the foot plate.
! Loosen the thumb screw between base and support
and swivel the support to the desired angle.
! Tighten the screw again.
At the beginning, drill at a low speed, as the drill bit enters into
the material with only a part of its cutting edge. If the drill
speed or pressure is too high, the drill bit may become erratic.
