Fixing on the floor by means of vacuum
Do not use the vacuum fastening on the wall or overhead!
Vacuum fixing may only be used if the area to be drilled is level, free of
pinholes and cracks, otherwise this method cannot be applied.
For the vacuum fixing you need the vacuum pump, plate and the vacuum
tube (see picture). These are available on request.
Connect the drill rig and the vacuum pump by means of the vacuum tube.
Bring the drill rig into the correct position and switch the pump on.
Check whether the four levelling screws in the base plate are completely
turned back and a vacuum of -0.8 bar minimum is achieved.
The vacuum pump has to run during the complete operation, it is to be
placed in such a position that you can monitor the pressure gauge at all
times.
Attention! It is important that the drill rig is tightly connected with
the ground. Incorrectly fixed drill rigs can cause injuries of the
operator and damages on the drilling unit.
drilling cause hits of the drill bit against the drilling wall, what can
lead to a breaking out of the segments. The drill bit can also cant in
the bore hole, what causes damages on this.
Vertical drilling
Switch the PRCD on.
Open the water supply.
Turn the motor on without touching the surface with the drill bit.
Turn the handle to lower the drill bit until it touches the surface.
In order to reach an exact centring of the drill bit, keep the feed
low for the first centimeter of cutting depth.
Then you can drill faster.
reduces the power. On the other hand, when the drilling speed is
too high, the diamond segments quickly become blunt.
Position the drill rig. Place the quick action bracing unit
as close as possible behind the column on the base of
the rig.
Fix the drill rig by turning the crank (G)
clockwise.
Secure the position by means of the
appropriate bolt (H).
