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).
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, 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 opera-►
tion. Remove shavings only when the machine is at a stand-
still. 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 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 satises the minimum require-
ments. 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.
Thermal overload protection
The machine is additionally equipped with thermal overload pro-
tection. If the machine becomes too hot, it switches off automati-
cally.
Carry out the following steps before continuing to work with the
machine:
Remove any blockages that may have occurred.
Allow the machine to run at no-load speed for approx. 2
minutes.
The machine is then ready for operation again.
Slip clutch
In the event of the drill blocking, the gearbox is protected by a slip
clutch.

Before using for the rst time
Transport inspection
The machine is supplied as standard with the components indi-
cated in chapter Components/scope of supply.
NOTE
Inspect the delivery for completeness and obvious signs of►
damage. Report an incomplete or damaged delivery to your
supplier/dealer immediately.
Preparations
This chapter contains important instructions for the necessary
preparations before starting work.
Additional safety measures for certain operations
Additional safety precautions must be taken for the following
operations with the machine:
Non-horizontal working position
WARNING
Risk of injury from the falling machine.
When working in inclined or vertical position and during over-
head work, the machine must be secured to prevent it from
falling using the safety chain (E) supplied.
Check the safety chain for proper function before every use.►
A damaged safety chain must not be used. Replace a dam-
aged safety chain immediately.
Attach the safety chain in such a way that the machine►
moves away from the operator in the event of slipping.
Lay the safety chain as tightly as possible around the handle►
of the machine.
Check the secure tting of the safety chain and lock before►
starting work.
Use the protective equipment stipulated in chapter►Personal
protective equipment.

46
Preparations
MAB 825/845
ENGLISH
Work on scaffolding
WARNING
Risk of falling from sudden oscillating movements of the
machine.
When working on scaffolding, the machine can make a sud-
den oscillating movement on starting or in the event of a power
failure.
Secure the machine with the safety chain (E) supplied.►
Wear a safety belt to protect yourself from falling.►
Check the condition of the substrate
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 (14) must be■
clean and grease-free.
The clamping surface must be completely smooth and level.■
NOTE
Clean the substrate and the magnetic foot (14) of the ma-►
chine before use.
Remove any unevenness and loose rust from the substrate.►
BDS offers special holding devices in its range of accesso-►
ries.
The best clamping effect is obtained on low-carbon steel sub-
strate with a thickness of at least 20 mm.

(minimum dimensions 100 x 200 x 20 mm) must be placed under
the workpiece. Secure the steel plate to prevent it from falling.
NF metals or workpieces with an uneven surface
A special holding device must be used when drilling in NF metals
or in workpieces with an uneven surface.
NOTE
BDS offers special clamping devices for tubes and non-►
magnetic materials in its range of accessories.
