Please ensure that the levelling screw is adjusted so that it does not protrude
from the bottom of the base, since otherwise the vacuum will be affected and
the rig may come loose from the mounting surface.
When connecting the vacuum onto a sufficiently powerful vacuum (min. – 0.8
bar). make sure that the seals are not worn out.
Connect the drill rig and the vacuum pump by means of a vacuum hose.
Get the drill rig in the correct position, open the valve on the coupling plate and
switch on the pump.
The vacuum pump must run during the whole working time and must be
placed so that one can see the manometer.
Make sure that the drill stand is fixed firmly before you start drilling!
Fastening by means of quick action bracing unit
In order to brace the drill rig by means of the quick action bracing unit, the
distance to the opposite wall must be between 1,7 m and 3 m.
Position the drill rig. Position the quick action bracing unit
as close as possible behind the support on the base of the
rig. Fix the drill rig by turning the crank (G) clockwise.
Secure in position by means of the appropriate bolt (H).
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.

To unfasten the vacuum connection, close the valve. This
opens a bleed valve through which the vacuum can escape.
Thus the rig can be activated if necessary when the vacuum
pump is running.
