Observe the following safety precautions to avoid injuring
yourself and/or others:
►Operate the machine only with the protective equipment
stipulated in these operating instructions (see section
Personal protective equipment).
►Do not wear protective gloves when the machine is running.
A glove can be caught by the drilling machine and torn off
the hand. Risk of losing one or more ngers.
►Remove loose jewellery before beginning work. Wear a hair
net if you have long hair.
►Always switch off the machine before changing tools,
performing maintenance or cleaning. Wait until the machine
has come to a complete standstill.
►Always remove the plug from the mains socket before
changing tools, cleaning or performing maintenance, in
order to avoid unintentional starting of the machine.
►Do not put your hand into the machine while it is in
operation. Remove shavings only when the machine is at a
standstill. Wear protective gloves when removing swarf.
►When working on scaffolding, the operator must be secured
with a safety belt as the machine can oscillate dangerously
in the event of interruption to the power supply.
►Check for secure clamping of the electromagnets on the
substrate before every use (see section Preparing).
►Secure the machine with the safety chain supplied when
working from an inclined or vertical position or during
overhead work. The machine could fall down if the magnet is
loosened or the power fails.
►Check that the tool is tightened securely before using (see
section Inserting the tool).
►Do not allow the connecting cable to hang over edges
(danger of tripping).

data (voltage and frequency) on the rating plate with those
of your mains power supply. The data must correspond in
order to avoid damage to the machine.
►Always carry the machine at the handle, not by the
connecting lead.
►Always pull the mains lead out of the plug socket at the plug,
not at the mains lead.
►Do not pinch the connecting lead.
►Do not expose the connecting lead to heat or chemical
liquids.
►Do not pull the connecting lead across sharp edges or hot
surfaces.
►Lay the connecting lead in such a way that it cannot be
caught and wound up in the rotating part of the machine.

NOTE
►The machine stops automatically of the magnetic clamp is
switched off or in the event of a power failure.
In order to prevent unexpected starting of the machine when the
magnetic clamp is switched on again or when the power supply
returns after a power failure ("restarting protection"), the machine
must be switched on at the ON/OFF switch again.

The magnet indicator provides a visual control of the magnet's
clamping force.
■Magnet indicator is lit GR EEN:
The magnet's clamping force satises the minimum
requirements. Machining can be carried out.
■Magnet indicator is lit RED:
Insufcient magnet clamping force. Machining must not be
carried out with the machine. This can be the case in the event
of insufcient material thickness, uneven surface or due to
paint, scale or zinc coatings.

The magnet clamping force is dependent on the condition of the
substrate. The clamping force is signicantly reduced by paint,
zinc and scale coatings and rust.
The substrate must satisfy the following preconditions in order
that a sufcient magnet clamping force can be achieved:
■The substrate must be magnetic.
■The clamping surface and the magnetic foot (12) must be
clean and grease-free.
■The clamping surface must be completely smooth and level.
NOTE
►Clean the substrate and the magnetic foot (12) of the
machine before use.
►Remove any unevenness and loose rust from the substrate.
►CS Unitec offers special holding devices in its range of
accessories.
The best clamping effect is obtained on low-carbon steel substrate
with a thickness of at least 3/4” (20 mm).

must be placed under the workpiece. Secure the steel plate to
prevent it from falling.
