Use On Thin Steel; Non-Ferrous Metals; Round Or Cambered Surfaces; Maintenance - Optimum OPTIdrill DM35 Betriebsanleitung

4.2.1

Use on thin steel

The magnetic drill adheres best to low-carbon steel that is at least 12 mm thick. For drilling a
hole into thin steel, a 12mm steel plate can be secured under the material at the place where
the magnetic stand is to be positioned.
4.2.2

Non-ferrous metals

To drill a hole in non-ferrous metal, the steel plate should be secured on the surface of the
material and the magnetic drill stand then placed on the steel plate.
4.2.3

Round or cambered surfaces

If you need to drill into a round or cambered surface, then the magnet block should be posi-
tioned with its longitudinal axis parallel to the axis of the camber. The open space between the
magnet block and the camber should be packed with steel wedges on both sides along the
entire length of the magnet block so that after switching on the magnet as many as possible
magnetic lines of force are conducted from the magnet pole through the wedges and the mate-
rial to the magnet block housing.
Ensure that the steel wedges on both sides of the magnet block are distributed such that the
axis of the drill bit is aligned directly to the centre of curvature; otherwise it could be diverted to
one side. By shaking the magnetic drill, make sure that the stand adheres properly to the mate-
rial.

Maintenance

Always keep the drill stand and magnetic base clean, to be able to work well and securely.

CAUTION!
If the replacement of the connecting line is required, then this must be done by an
electrician, to avoid any safety risks.
CAUTION!
Check the surface of the magnetic base for damage and replace if necessary. Damaged
magnetic surfaces reduce the holding force and cause the magnetic drill to move away
from the surface with the maximum possible torque of the drilling spindle.
After an operating time of approximately 90 days, the carbon brushes of the drive motor

should be replaced.
Gears running in the oil bath are maintenance-free. It is not necessary to replace the oil.
