bend if allowed to rotate freely without contacting the workpiece,
resulting in personal injury.
c) Apply pressure only in direct line with the bit and do not
apply excessive pressure. Bits can bend causing breakage or loss
of control, resulting in personal injury.
Additional Safety and Working Instructions
Use protective equipment. Always wear safety glasses when
working with the machine. The use of protective clothing is re-
commended, such as dust mask, protective gloves, sturdy non-slip
footwear, helmet and ear defenders.
Wear protective gloves when replacing the core bit. The core bit can
become hot after prolonged operation of the power tool.
The dust produced when using this tool may be harmful to health.
Do not inhale the dust. Use a dust absorption system and wear a
suitable dust protection mask. Remove deposited dust thoroughly,
e.g. with a vacuum cleaner.
Do not machine any materials that present a danger to health (e.g.
asbestos).
Keep mains lead clear from working range of the machine. Always
lead the cable away behind you.
When working in walls ceiling, or oor, take care to avoid electric
cables and gas or waterpipes.
The built-in friction clutch only reacts to jerky locking, which is why
you should always use the additional handle.
Before use check machine, cable, and plug for any damages or
material fatigue. Repairs should only be carried out by authorised
Service Agents.
Pay attention that neither persons in the working area nor the
power tool itself come into contact with the water that comes out.
After interruption of your work, restart the tool only after having
made sure that the drill bit is moving freely.
Never lay the power tool down until the accessory has come to a
complete stop. The spinning accessory may grab the surface and pull
the power tool out of your control.
Examine the core bit before inserting it. Use only core bits that are
in perfect condition. Damaged or deformed core bits can lead to
dangerous situations.
Check the proper seating of the core bit. Incorrectly or insecurely
fastened core bits can become loose during operation and may pose
a danger.
The tool may be used only in two-hand operation or with the drill rig.
Always keep a safe footing and hold machine with both hands. Keep
children or animals away from working area.
When drilling through walls or ceilings, ensure to protect persons
and the work area on the other side. The bit may extend through
the hole or the core may fall out on the other side.
When drilling overhead, always use the liquid collection device
speci ed in the instructions. Do not allow water to ow into the
tool. Water entering the power tool will increase the risk of electric
shock.
Switch the device o immediately if the insertion tool stalls! Do
not switch the device on again while the insertion tool is stalled,
as doing so could trigger a sudden recoil with a high reactive force.
Determine why the insertion tool stalled and rectify this, paying
heed to the safety instructions.
Possible causes may be:
• it is tilted in the workpiece to be machined
• it has pierced through the material to be machined
• the power tool is overloaded
Do not reach into the machine while it is running.
The insertion tool may become hot during use.
WARNING! Danger of burns
• when changing tools
• when setting the device down
Chips and splinters must not be removed while the machine is
running.
Always disconnect the plug from the socket before carrying out any
work on the machine.
When working with large drill diameters, the auxiliary handle must
be fastened in a right angle with the main handle (see illustrations,
section „Twisting the handle").
SPECIFIED CONDITIONS OF USE
The machine is intended for dry drilling in brick and tile and wet
drilling in concrete.
Do not use this product in any other way as stated for normal use.

MAINS CONNECTION

Appliances used at many di erent locations including wet room
and open air must be connected via a residual current device (FI,
RCD, PRCD) of 30mA or less.
Connect only to single-phase AC system voltage as indicated on
the rating plate. It is also possible to connect to sockets without an
earthing contact as the design conforms to safety class II.
Only plug-in when machine is switched o .
Keep mains lead clear from working range of the machine. Always
lead the cable away behind you.
Before use check machine, cable and plug for any damages or
material fatigue. Repairs should only be carried out by authorised
Service Agents.

WORKING INSTRUCTIONS

To gain a better drill progress take out the centre bit after having
reached a depth of about 10-15 mm. Insert core cutter into the
existing groove and let machine run up smoothly.
Bore-holes which don't have to be applied exactly can be drilled
without a centre bit. For that purpose apply the core cutter
slantingly and put the machine slowly straight when a depth of
about 5 mm has been reached. (This is only possible when using
short core cutters!)
If drill cores should come loose, take core cutter from the material
and remove drill cores.
For best performance the diamond segments should be „roughed-
up" to expose the fragments of diamond: To expose the diamond
fragments rub surface of segments with stone

WATER CONNECTION

A water connection is available on the tool to cool the wheel and
reduce the formation of dust. The water connection should be used
on all concrete cutting applications.
For best results, allow the water to coat the entire cutting wheel
before operation.
