Care and Maintenance
Always keep the drill rig clean, especially the column with the toothing and
the 4 sliding pieces in the machine holder.
In order to allow the free movement of the pinion shaft, it should be slightly
lubricated.
In order to achieve a good performance of the drill rig, the 4 sliding pieces in
the machine holder have to move along the column without slackness.
Attention:
After every tenth drilling you should check if the sliding pieces have got loose-
fitting due to drilling vibration.
If the position should have changed, it can be readjusted as follows:
Loosen the counter nut on the Allen
screw by means of an jaw wrench
SW 17
Adjust the Allen screws and the
position of the thrust piece to the
column by means of a hex head
wrench SW 8.
Tighten the counter nut again and
check whether the carriage moves
easily on the column.
