Safety
CAUTION
When using electrical tools, the following fundamental
precautions must be taken to protect against electric shock
and the risk of injury and re!
Fundamental safety precautions
Do not use the machine in ammable or potentially explosive■
environments.
Persons who due to their physical, mental or motor response■
abilities are unable to operate the machine safely may only

Store the machine in a dry, temperate location out of the reach■
of children.
Do not leave the machine standing outdoors and do not ex-■
pose it to moisture.
Make sure that your work area is sufciently lit (>300 Lux).■
Do not use low power machines for heavy working.■
Make sure that your workplace is clean.■
Keep the machine clean, dry and free of oil and grease.■
Follow the instructions on lubricating and cooling the tool.■
Electric shock hazard
DANGER
Danger to life by electric shock!
Contact with live wires or components could lead to seri-
ous injury or even death!
Observe the following safety precautions to avoid electric
shocks:
Do not open the housing of the machine. Risk of electric►
shock if live terminals are touched.
Never immerse the machine or the plug into water or other►
liquids.
Use only extension leads or cable drums with a cable cross-►
section of 1.5 mm².
Only use extension leads that are approved for the place of►
work.
Check the condition of the extension lead regularly and►
replace if damaged.
Avoid direct body contact with grounded parts (e.g., tubes,►
radiators, steel girders) to reduce the risk of electric shock in
the event of a defect.

Risk of injury
WARNING
Improper handling of the machine increases the risk of
injury!
Observe the following safety precautions to avoid injuring your-
self and/or others:
Operate the machine only with the protective equipment►
stipulated in these operating instructions (see section Per-
sonal protective equipment).
Remove loose jewellery before beginning work. Wear a hair►
net if you have long hair.
Always switch off the machine before changing tools, per-►
forming 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 op-►
eration. Remove shavings only when the machine is at a
standstill.
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 over-
head 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 (dan-►
ger of tripping).

Prevention of damage
CAUTION
Potential property damage in case of inexpert handling of
the machine!
Observe the following instructions to avoid property damage:
Before connecting the machine, compare the connection►
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 connect-►
ing 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.

Safety installations
Restarting protection
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.
Magnet indicator
The magnet indicator provides a visual control of the magnet's
clamping force.
Magnet indicator is lit■GREEN:
The magnet's clamping force satises the minimum require-
ments. Machining can be carried out.
Magnet indicator is lit■RED:
Insufcient magnet clamping force. Machining must not be
carried out with the machine. This can be the case in the event
of insufcient material thickness, uneven surface or due to
paint, scale or zinc coatings.
