EIBENSTOCK Vakuum Technik Notice Originale page 17

Fitting the vacuum set:
Position the coupling plate of the vacuum set on the drill rig base as shown.
The coupling plate is fastened to the drill rig base from below with the help of the
M8x30 cap bolt and washer.
Check that the coupling plate is secure.
Place the foam rubber seal into the recess on the bottom of the base.
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.
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.
