Before starting work

WARNING!
For drilling jobs, it is necessary to clamp the workpiece firmly to prevent the bit catching
on the pieces. A machine vice or clamping claws is a suitable clamping device.
Before starting work, select the desired speed. It is depending on the used drilling diameter and
on the material.
If required, adjust the desired drilling depth by means of the drilling depth stop in order to obtain
a uniform drilling depth.
4.9

During work

WARNING!
Seizing of clothes and / or hair.

Make sure to wear well-fitting work during drilling work.

Do not use gloves.

If necessary, use a hairnet.
The smaller the bit the more easily it may break. In the case of deep drilling, remove the bit
from time to time to remove filings from the drill. Add a few drops of oil to reduce friction and
prolong the service life of the bit.

Spindle sleeve feed

CAUTION!
Risk of impact by the spindle sleeve lever upon completion of the drilling feed. The
return spring biases and discharges the stored energy.
Move the sleeve downward by means of the spindle sleeve lever. The sleeve is returned to its
initial position by means of the spring force.

CAUTION!
Preventive safety measure. Disconnect the machine from the electrical supply.
ATTENTION!
The tool and/or the drill chuck will fall down. Hold the tool or the drill chuck while drifting it
