Connect the drill rig and the vacuum pump by means of a vacuum hose.
Get the drill rig in the correct position and switch on the pump.
Make sure, that all four levelling screws in the foot plate are turned back and
that a low pressure of -0,8 bar is reached.
By means of pressing the valve button in the handle the drill stand can be
unburdened (vacuum is escaping) and can be readjusted
.
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 dowels in concrete
To mount the drill stand by means of dowels it is necessary to remove the
vacuum grip and the base gasket from the base plate.
For brickwork, Rawl-Dowels
must be used.
Mark the position of the drill holes for the
fastening on the surface to be drilled.
Drill a hole (Ø 15) 50 mm deep (A), into
which the dowel M12 (B) is to be placed;
insert and secure the dowel with the
doweling tool (C).
Screw the quick action clamping screw (D)
into the dowel.
Install the drill rig.
Fix the washer (E) and finally the
fastening nut (F) on the quick action
clamping screw (D).
Tighten the fastening nut (F) with a
wrench SW 27.
Before and after tightening the nut (F),
the 4 adjustable screws have to be
adjusted in order to adapt the rig to the
surface.
Do check whether the drill rig is
installed safely and firmly.
