Removal of the core when it sticks in the drill bit:
Separate the drill bit from the motor (if possible).
Put the drill bit in a vertical position.
Knock carefully on the pipe by using a wooden hammer shank till the
drilling core slips out. Never throw the drill bit against a wall by force
or set about it with tools, such as hammer or jaw wrench. Otherwise,
the pipe could go out of shape and neither the drilling core can be
extracted nor the drill bit is reusable.
Removal of the core by blind holes:
Break off the core with a cotter or lever, or in pieces. Lift the core out with
appropriate tongs or drill a hole with a dowel in the core, screw an eyebolt
in and pull the core out.
Since the drill rig does not belong to the supply, some of its most
important features are described here.
For this purpose, please refer to the drill rig's operating
instructions.
Fixing to Drill rig
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.
Rig Drilling
The ETN 162/3 is equipped with a special
accomodation for the diamond drill rig BST 182 V/S.
For mounting the tool to the drill rig, the handle may
remain at its place.
Move the machine holder upwards until it locks in
the top position.
Open the fixing by turning the locking screw with the
feed lever until the guideway is free
Insert the tool into the drill rig.
Fix the tool by turning the locking screw with the
feed lever.
In doing so, the screw must engage the hole in the
v-block.
