Fastening of the Drill Rig
The diamond core drill ESD 200 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.
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 35720000).
Drill a hole with a diameter of 16 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 tightly.
Adjust the drilling unit by means of the four screws in the foot plate
and tighten the wing nut firmly with an open-end spanner (SW27)
after adjustment.
Vertical drilling
Switch on the PRCD switch.
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.
At the beginning, it is better to drill very slowy because the bit only
meshes with a fraction of its cutting area with the material. If you drill
too fast or with a pressure which is too high, the bit can be off centre.
You have hit reinforced iron when you recognise while drilling that the feed
rate gets very low, when you need to use more force.
