Fastening of the drill stand by means of a vacuum plate
(as accessories available)
Don't use the vacuum mounting on the wall and overhead!
For a low-pressure mounting the surface which is to be drilled must be not
porous, must be flat and free of cracks.
If this is not the case, this kind of mounting can't be use. For the vacuum
mounting you need a vacuum pump, a vacuum plate and vacuum hoses
(see illustration). These items are available on request.
Connect the drill rig with the vacuum plate and the vacuum pump by means of
the vacuum tube with the male coupling of the vacuum plate.
Get the drill rig with the vacuum plate in the correct position and switch on the
pump.
Make sure, that all four levelling crews in the foot plate are turned back and that
a low pressure of -0,8 bar is reached.
The vacuum pump must run during the whole working time and has to be
placed so that one can see the manometer.
Attention! It is important, that the drill unit 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.
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.
H
G
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).
