Connect the drill rig with the vacuum plate and the vacuum pump by means of a
vacuum hose.
Get the drill rig with the vacuum plate in the correct position, open the valve on the
coupling plate and switch on the pump.
When connecting the vacuum onto a sufficiently powerful vacuum (min. – 0.8 bar).
Make sure that the seals are not worn out.
The vacuum pump must run during the whole working time and must be
placed so that one can see the manometer.
Attention!
It is important, that the drill rig is firmly connected to the surface. If not fixed
correctly, injuries to the operator or damages to the drilling unit may be
caused. Uncontrolled movements during drilling will cause the drill bit to hit
the surface to be drilled which may lead to a chipping of the segments. The
drill bit might also tilt in the bore hole which consequently will damage it.
Fixing the Core Drill Motor
Caution! When mounting the machine, risk of squashing.
Wear protective gloves!
Setting up the mounting plate
Move the machine holder upwards until it locks in
the top position.
Use the turnstile to open the locking device of the
mounting plate (see arrow).
Remove it and connect it to the core drill motor as
described subsequently.
