You have chosen Marcrist for your diamond drilling system. We thank you for your choice and
confidence!
Marcrist has the sole am ition to lead in diamond technology and quality. The Result is outstanding
quality for the professional tradesman.
Marcrist is accepted worldwide as a technology leader in diamonds. Marcrist diamond tools are
used y professional tradesmen who value performance, safety and the lowest possi le drilling costs.
The est diamond drilling machine is only as good as the cores which are eing used. The machine
cannot drill if the cores don’t drill!
When choosing diamond cores always consider the cost per hole rather than just the lowest
purchase price.
A etter core may cost a little more ut it will invaria ly last much longer (up to 20 times) and drills
at least twice as fast and does not damage the machine!
Because of this, etter cores result in costing you etween 10–20 times less than cheap cores.

aa))Keep work area clean and well lit. Cluttered or dark areas invite accidents.
bb))Do not operate power tools in explosive atmospheres, such as in the presence of
flamma le liquids, gases or dust. Power tools create sparks which may ignite the
dust or fumes.
cc))Keep children and ystanders away while operating a power tool. Distractions
can cause you to lose control.
22)) EElleeccttrriiccaall ssaaffeettyy
aa))Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
bb))Avoid ody contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your ody is
earthed or grounded.
cc))Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
dd))Do not a use the cord. Never use the cord for carrying, pulling or unplugging
the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
ee))When operating a power tool outdoors, use an extension cord suita le for
outdoor use. Use of a cord suita le for outdoor use reduces the risk of electric shock.
ff)) If operating a power tool in a damp location is unavoida le, use a residual
current device (RCD) protected supply. Use of an RCD reduces the risk of electric
shock.
33))PPeerrssoonnaall SSaaffeettyy
aa))Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools
may result in serious personal injury.
bb))Use personal protective equipment. Always wear eye protection. Protective

4
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
cc))Prevent unintentional starting. Ensure the switch is in the off-position efore
connecting to power source and/or attery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that
have the switch on invites accidents.
dd))Remove any adjusting key or wrench efore turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in personal
injury.
ee))Do not overreach. Keep proper footing and alance at all times. This ena les
etter control of the power tool in unexpected situations.
ff))Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewellery or long hair can e
caught in moving parts.
gg))If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection can
reduce dust-related hazards.
44))PPoowweerr ttooooll uussee aanndd ccaarree
aa))Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the jo etter and safer at the rate for which it was
designed.
bb))Do not use the power tool if the switch does not turn it on and off. Any power
tool that cannot e controlled with the switch is dangerous and must e repaired.
cc))Disconnect the plug from the power source and/or the attery pack from the
power tool efore making any adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of starting the power tool
accidentally.
dd))Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
ee))Maintain power tools. Check for misalignment or inding of moving parts,
reakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired efore use. Many accidents
are caused y poorly maintained power tools.
ff))Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to ind and are easier to control.
gg))Use the power tool, accessories and tool its etc. in accordance with these
instructions, taking into account the working conditions and the work to e
performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.
55))SSeerrvviiccee
aa))Have your power tool serviced y a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.

The DDM2 – 230 features a residual current device that cuts off the unit within 15
milliseconds in the event that there is a difference (>10 mA) etween the currents flowing in
and out of the unit. The user is therefore protected should any water come into contact with
any of the electronic components.
Never use the tool without the RCD provided with the tool. Always test the correct
operation of the RCD efore starting work (see elow).
To test the RCD unit is working correctly, proceed as follows:
• Plug in machine into the appropriate power supply (11).
• Depress the reset utton on RCD (10) (Red light indicator is illuminated).
• Switch on the machine y depressing trigger (1).
• Depress the test utton on RCD (10).
• The switch must reak the circuit (red light indicator goes off and machine switches off).
• RCD is working correctly.
If in the test mode the switch does not reak the circuit DO NOT USE.
Take the DDM2 - 230 to your nearest Marcrist Distri utor to arrange inspection &
repair.
It is not permitted to make any modifications to the machine, in
particular it is not allowed to open the RCD or to repair or to replace the ca le. If
it is need of inspection or repair take to your nearest Marcrist distri utor.
Never use the RCD as a main switch. Always switch on the RCD under no
load condition.
If an extension ca le is to e used always ensure it is of an approved type
for application and the ca le is of a minimum rating for the machine. Always
operate extension cord with the ca le reel fully unwound.

11..Ensure power supply is off. When selecting any gear rotate the drill spindle (4)
slowly while turning the selector (6) to the appropriate speed. This will ensure smooth
selection of gear.
22..Do not change gears when the tool is rotating and in use. Failure to follow this
instruction could result in damage to the machine.
33..See speed chart on page 12. Adjust the speed for harder/softer materials
accordingly. Lower speeds should e used for harder materials, higher speed for
softer materials.
AAsssseemmbbllyy && ooppeerraattiioonn
11..Plug in machine into the appropriate power supply (11).
22..Test correct operation of RCD (10) unit efore use (see a ove).
33..Disconnect power. For core drills with 1/2” BSP thread, screw 1/2” BSP adaptor (9)
into drill spindle (4).
44..Screw core drill with 1/2” BSP thread onto adaptor (9).
55..For core drills with 11/4” UNC thread, screw directly into drill spindle (4).
66..Hold firmly the side handle (7) with one hand and main handle (5) with other hand.
77..To operate the machine depress the trigger (1).
..With core drill running approach the surface to e drilled with the drill at an angle of
approximately 15 degrees. As the segments ite gradually ring to a horizontal
position and continue drilling.
99..For continuous operation depress the trigger lock utton on handle (5) while trigger
(1) is operated.
1100..Apply only gentle pressure during operation. Excessive force may damage the
machine or accessories and could result in a shortening of tool life.
1111..To stop drilling depress the trigger (1).
1122..Disconnect the power from the supply.
1133..Remove the core from DDM2 - 230 or adaptor (9) using the spanners provided.
Drilling aids and accessories are availa le from Marcrist. Contact your Marcrist dealer
for more information.
Always follow the manufactures guidelines when attaching accessories to the machine.

11..Connect the 350mm long water hose (8) on DDM2 - 230 to a suita le water supply
y push fitting into a “Gardena” or “Hozelock” type fitting which is attached to a
hose pipe. The hose pipe could e typically etween 5m - 20m in length.
22..Turn on water supply.
33.. Turn on tap on the water hose so that a steady flow of water cools the segments on
the core.
Do not exceed the recommended maximum water pressure of 2 ar.
The hose (8) should always e checked that is in a satisfactory condition
efore use and is not split and does not leak water. DO NOT USE IF THE
HOSE IS LEAKING WATER OR IS DAMAGED.
A minimal flow of water direct to the core segments & material helps cool the drilling
area & improve drilling performance.
Keep water away from the parts of the tool & away from persons in the
working area.
Always test the correct operation of the RCD efore starting work.
If the plug or supply ca le needs replacing then take the DDM2 - 230 to your

Certain very hard materials such as reinforced concrete can present pro lems for dry
drilling. They may cause excessive heat & consequent polishing ( lunting) of the
diamond segment on the core.
This can result in poor drilling performance and can e overcome y connection of a
suita le water supply onto the hose of the DDM2 - 230 machine using a “Gardena” or
“Hozelock” type fitting as shown in the diagram elow.
