Warning:
Setup work may only be carried out
after the machine is protected
against accidental starting.
With pressed emergency stop
button.
Never place your fingers in a position
where they could contact any rotating
tool, chuck or cutting chips.
Remove cutting chips with the aid of
an appropriate chip hook when the
machine is at a standstill only.
Never stop the rotating chuck or tool
with your hands.
Always close the chuck guard before
you start the machine.
Secure work piece to the table with
clamps or a vice to prevent rotating
with the drill bit.
When using a vice, always fasten it to
the table.
Check the save clamping of the work
piece, chuck and tools before starting
the machine.
Never do any works "freehand" (hand-
holding the work piece rather than
supporting it on the table).
Support long work pieces with helping
roller stands.
Always adjust the depth stop to
prevent drilling into the table or into
the workholding device.
Feed a drill bit into the material with
only enough force to allow the drill bit
to work. Feeding too slowly may
cause burning of the work piece or
tool. Feeding too quickly may cause
the motor to stop and/or the drill bit to
break.
Do not use wire wheels or grinding
wheels on this machine.
Never cut magnesium-
high danger to fire!
Measurements and adjustments may
be carried out when the machine is at
a standstill only.
In case of danger push the
emergency stop button.
