Fastening of the Drill Rig
The diamond core drill EBM 352/3 may only be used mounted on a drill
rig. Since the drill rig is not included in the delivery, we point out some
important kinds of assembly.
For this purpose, please refer to the drill rig's operating instructions.
Vacuum fastening:
For the vacuum, make sure that it is sufficient (minimum -0.8 bar). Make
sure that the gaskets are not worn.
Attention! Do not use the vacuum fastening on the wall or overhead!
Please ensure that the leveling screws are adjusted in such a way that they
do not protrude from the underside of the drill stand foot, otherwise the
vacuum is affected and the stand may come away from its support.
Dowel fastening:
The most common way of fastening is dowel fixing.
If possible, use metal dowels only. The dowel diameter must not be
smaller than 12 mm.
In order to fasten the drilling unit correctly, you need the fastening set
(order number 35721).
Drill a hole with a diameter of 15 mm, 50 mm deep. Make sure that
the hole is free of dust.
Insert a dowel and open it with an expanding mandrel.
Screw the thread rod into the dowel.
Put the drilling unit with the deep hole in the base onto the thread rod.
Place the washer and screw the butterfly nut very tightly.
Adjust the drilling unit in the platform by using the four screws.
Vertical drilling
Switch the PRCD on.
Open the water supply.
Switch the motor on without touching the surface with the drill bit.
Turn the handle to bring down the drill bit until it contacts 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. A too small drilling speed reduces the
power. On the other hand, when the drilling speed is too high, the
diamond segments quickly become blunt.
Angular drilling
Remove the screw in the foot base which arrests the column at 90°.
Loosen the two screws on the base of the column and turn the
column to the requested angle.
Retighten the screws again.
