Care and Maintenance
Before the beginning of the maintenance or repair works you
have to disconnect the plug from the mains!
Machine:
Repairs may be executed only by appropriately qualified and experienced
personnel. After every repair the machine has to be inspected by an
electric specalist. Due to its design, the machine needs a minimum of care
and maintenance. Regularly the following works have to be carried out or
rather the component parts have to be inspected:
Clean the drilling unit after you have finished drilling.
Then grease the thread of the drill spindle.
The ventilation slots always have to be clean and open.
Pay attention that no water gets into the machine during the cleaning
process.
After the first 150 hours of operation you have to change the gearbox
oil.
Gearbox oil changes cause a considerable longer lifetime of the
gearbox.
After approx. 200 hours of operation the carbon brushes have to be
checked by an electric specialist and if necessary removed them (use
original carbon brushes only).
Have switch, cable and plug checked by an electric specialist quarterly.
Drill Rig:
Always keep the drill rig clean, especially the column with the toothing
and the 4 sliding pieces in the mounting plate. 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
backlash.
If the position has changed, it can be readjusted as follows:
Loosen the counter nut on the Allen
screw by means of an jaw wrench
SW17
Adjust the Allen screws and the
position of the thrust piece to the
column by means of a hex head
wrench.
Tighten the counter nut again and
check whether the carriage moves
easily on the column.
