WARNING!
The vibration and noise emission level given in this information sheet has
been measured in accordance with a standardized test given in EN 62841 and may
be used to compare one tool with another. It may be used for a preliminary
assessment of exposure.
The declared vibration and noise emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration and noise emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration and noise should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration and/or noise such as: maintain the tool and the accessories, keep the hands warm, organization of work patterns.
Wear ear protectors. Exposure to noise can cause hearing loss.
WARNING Read all safety warnings and all instructions.
Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury.
Save all warnings and instructions for future reference.
DRILL SAFETY WARNINGS
a) Wear hearing protection when diamond drilling. Exposure to noise can cause
hearing loss.
b) Use auxiliary handle(s), if supplied with the tool. Loss of control can
cause personal injury.
c) Brace the tool properly before use. This tool produces a high output torque
and without properly bracing the tool during operation, loss of control may
occur resulting in personal injury.
d) Hold the power tool by insulated gripping surfaces, when performing 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.
Safety instructions when using long drill bits
a) Never operate at higher speed than the maximum speed rating of the drill
bit. At higher speeds, the bit is likely to bend if allowed to rotate freely
without contacting the workpiece, resulting in personal injury.
b) Always start drilling at low speed and with the bit tip in contact with the
workpiece. At higher speeds, the bit is likely to 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 recommended, 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 floor, 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 specified in the instructions. Do not allow water to flow into the tool. Water entering the power tool will increase the risk of electric shock.
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 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 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.
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 „roughedup“ 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.
TROUBLESHOOTING
Vibration
- Stop drilling.
- Turn core drill off .
- Always disconnect the plug from the socket before carrying out any work on the machine.
- Check for loose nuts and bolts. Tighten if required.
- Check for excessive core drill bit runout. Replace if required. If vibration continues to occur, remove the core and loose material.
If vibration continues to occur after attempting these measures, return the rig to the nearest MILWAUKEE service facility.
Core drill bit Binding
Core drill bit binding is caused by one of two things: a dull (glazed) core
drill bit or a poorly stabilized stand. Causes of core drill bit glazing:
- Wrong RPM for core drill bit diameter
- High feed pressure
- Low feed pressure
- High steel content in work surface
- Large, hard aggregate
- Too much water
- Low motor power
A sharp core drill bit typically has good diamond exposure and will cut/grind almost anything in its path, including embedded steel.
MAINTENANCE
Always disconnect the plug from the socket before carrying out any work on the machine.
If the replacement of the supply cord is necessary, this has to be done by the manufacturer or his agent in order to avoid a safety hazard.
The ventilation slots of the machine must be kept clear at all times.
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 at: Techtronic Industries GmbH, Max‑Eyth‑Straße 10, 71364 Winnenden, Germany.
