WARNING Read all safety warnings and all instruc-
tions. Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

DRILL SAFETY WARNINGS

Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
Hold power tool by insulated gripping surfaces, when perfor-
ming an operation where the cutting accessory may contact
hidden wiring or its own cord. Cutting accessory contacting a
"live" wire may make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
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.
GB
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.
Keep mains lead clear from working range of the machine. Always
lead the cable away behind you.
When working in walls ceiling, or floor, take care to avoid electric
cables and gas or waterpipes.
Clamp your workpiece with a clamping device. Unclamped workpi-
eces can cause severe injury and damage.
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.
Do not machine any materials that present a danger to health (e.g.
asbestos).
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.
Do not expose the drill stand to rain and do not use in damp or non-
flameproof rooms.
Always keep a safe footing and hold machine with both hands. Keep
children or animals away from working area.
Always use suitable fixing means (impact anchor, knurled threaded
rod, quick-acting nut) to secure the drill stand to the substrate that is
to be machined.

Perform overhead drilling only with suitable protective appliances
(water catcher).
Switch the device off 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 can be:
• it is tilted in the workpiece to be machined
• breakage of the material to be used
• 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
Always disconnect the plug from the socket before carrying out any
work on the machine.
SPECIFIED CONDITIONS OF USE
The machine is intended for dry drilling in brick and tile and wet
drilling in concrete.

MAINS CONNECTION

Appliances used at many different 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 off.

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

MAINTENANCE

The ventilation slots of the machine must be kept clear at all times.
If the supply cord of this appliance is damaged, it must only be
replaced by a repair shop appointed by the manufacturer, to avoid
hazardous situations.
Use only Milwaukee accessories and Milwaukee spare parts. Should
components need to be replaced which have not been described,
please contact one of our Milwaukee service agents (see our list of
guarantee/service addresses).
If needed, an exploded view of the tool can be ordered. Please
state the Article No. as well as the machine type printed on the
label and order the drawing at your local service agents or directly
