ROTHENBERGER RODIADRILL 1800 DWS - Manual (Page 20)

16 ENGLISH
In case of need, repeat the process or turn the core bit using the flat wrench.
Please note: Switch off the PRCD switch!
Optional: Dry drilling
Reinforced concrete only wet drilling!
 Switch on the motor and the vacuum cleaner.
 Apply the diamond drill bit and continue to drill using light, consistent follow-up pressure.
 Occasionally with draw the drill bit slightly from the bore so that the drilling mud or dust is
removed.
 Shut down the motor once the desired drilling depth has been achieved and pull the drilling
bit out of the borehole slowly
 Shut down the vacuum cleaner.
Removal of the drilling core on through borings
Please take precautions to prevent physical injuries or property damage.
 Allow the drilling core to fall out of the bit.
If the core should jam in the bit, use a rod to push it out from the rear.
Avoid damage to the ground.
On no account use a hammer or spanner to hit the outside of the drill bit in order
to release the core. This could deform the pipe and it would then definitely no
longer be possible to remove the drilling core from the bit.
Removal of the drilling core from tapped blind holes
 Use a screwdriver, chisel or similar tools to penetrate the annular gap that has emerged and
break and remove the core by means of a brief, forceful lateral jerk or hammer blow.
The deeper the borehole, the easier it is to break the cores. Thus, optimal results are achieved if
the borehole depth is at least the same as the diameter of the drill bit.
5 Care and Maintenance
In order to avoid damage to the equipment and guarantee trouble-free work, all parts must be
cleaned and lubricated regularly.
Rub off the equipment after every drilling job and blow out using compressed air.
If it is foreseeable that the equipment will not be used for a longer period of time, remove the drill
bit from the motor. If this is not observed, the drill bit and motor shaft can be corroded together in
unfavourable circumstances. It would be very difficult to separate both parts, causing damage.
The following work should be carried out on a weekly basis at least. Carry out on an
appropriately more frequent basis in the case of more intensive work.
– Check and replace carbon brushes if necessary approximately every 250 operating
– use a fine brush to clean the collector cavity.
Important! All maintenance, overhauling and repair work must only be carried out by trained
specialised staff.
