CALIFORNIA PROPOSITION 65 MESSAGE
SILICA DUST WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition
may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz,
brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of
airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In ad-
dition, California and some other authorities have listed respirable crystalline silica as a substance
known to cause cancer. When cutting such materials, always follow respiratory precautions.
Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks
or surgical masks without a NIOSH approval number are not recommended because they do little to
protect the worker. For more information about respirator programs, including what respirators have
received NIOSH approval as safe and effective, please visit the NIOSH website at:
http://www.cdc.gov/niosh/topics/respirators
Observe OSHA regulations for respirator use (29 C.F.R.§1910.134).
Visit http://www.osha.gov for more information.
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-
tain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead, from lead-based paints
• Crystalline silica, from bricks and cement and other masonry products
• Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:
http://www.osha.gov/dsg/topics/silicacrystalline/index.html
http://www.cdc.gov/niosh/docs/96-112/
http://oehha.ca.gov/prop65/law/P65law72003.html
http://www.dir.ca.gov/Title8/sub4.html
http://www.P65warnings.ca.gov
Your risk from these exposures varies depending on how often you do this type of work. To reduce
your exposure to these chemicals, work in a well-ventilated area, and work with approved safety
equipment, such as dust masks that are specially designed to lter out microscopic particles. Where
use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec-
tion, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.
MK-2000P SAFETY
Diamond tools improperly used are dangerous. Comply with American National Standards Institute
Safety Code, B7.1 and, Occupational Safety and Health Act covering Speed, Safety Guards, Flanges,
Mounting Procedures, General Operating Rules, Handling, Storage and General Machine Conditions.

OPERATING THE MK-2000P
Ideal for drilling holes in oors, walls, ceilings and for all concrete anchoring systems. Fast and ef-
cient drilling of reinforced concrete, concrete, brick, block and stone.
The MK-2000P is equipped with an electronic ON/OFF switch.
Each time the switch is pressed, the speed of the drill becomes higher. This allows very precise drill-
ing. Under normal working conditions, always operate the MK-2000P at maximum speed.
In hand held drilling operations, only use the MK-2000P with the Auxiliary Handle xed. The Auxiliary
Handle must be tightened on the collar, by turning the lever.

MK-2000P PRODUCT SPECIFICATION

OVERLOAD PROTECTION
The speed of the drill will need to be adjusted in accordance with the size of the core bit being used.
The speed of the drill is adjusted by rotating the Speed-selector in the clockwise direction, while turn-
ing the drill shaft by hand until the clutch is engaged.
If the Speed-selector is in the “o” position, drill speed can be adjusted from 0 to 1000 rpm.
If the Speed-selector is in the “oo” position, drill speed can be adjusted from 0 to 2000 rpm.
It is easier to start a hole with a centering bit. The switch allows the drill to be operated at slow speed
for safely introducing the bit into the material. A normal pilot hole should be from .2 to .4 inches (5 to
10 mm) in depth. Once the pilot hole is created, the centering bit can be removed and replaced for full
speed operation.
If the core bit is suddenly blocked in the hole, a clutch will slip, disengaging the bit from the motor.
If excessive penetration speed results in an overload condition, an electronic switch will open discon-
necting the motor from the power supply.
Once the drill is removed from the hole and the electronic switch is reset, coring may resume.
If the drill is operated in a continuous overload condition and the Electronic Overload Protective device
fails, the Thermal Overload protective device will interrupt power to the motor.
Once actuated, the motor must be allowed to cool to reset the Thermal Overload protective device.
Time required for the Thermal Overload protective device to reset will vary depending on the tempera-
ture of the motor and ambient temperature.
To protect the operator and the drill, the MK-2000P is equipped with three overload protective devices -
mechanical, electronic and thermal. In case of overload, the MK-2000P is equipped with warning device.
For core bits with diameters above 2.8 in. / 70 mm, operate the drill using the “o” (0 to 1000) rpm range.
For core bits with diameters below 2.8 in. / 70 mm, operate the drill using the “oo” (0 to 2000) rpm range.
1. When using the handheld method, operate the drill in the 0 to 2000 rpm range only.
2. Always check the core bit manufacturer’s recommendation for use.
3. Gear shifting should only be performed in the clockwise direction when the drill is stopped.

MK-2000P MAINTENANCE
WATER SUPPLY
CARE AND MAINTENANCE
The MK-2000P is equipped with an intake cooling water ow control valve that can be placed vertically
of horizontally. A quick disconnect is supplied with the unit for ease of operation.
Water ow enters through the ow control valve and exits directly through the center of the motor shaft.
Cooling ow may be adjusted using the cooling water ow control valve.
Clean the MK-2000P following use.
Do not allow particles or parts to penetrate inside the tool.
The carbon motor brushes require inspection by a qualied maintenance technician after 300 hours of
operation. If the brushes are shorter than .2 inches (5 mm), they must be replaced.
During inspection of the motor brushes, the motor commutator must also be inspected. In case of ir-
regular coloring or scratches, the commutator must be repaired by a qualied service center.
After replacement, the motor brushes must be run at an idle for 20 minutes.
The MK-2000P requires inspection and gearbox cleaning by a qualied service center after 500 hours
of operation.
Do not operate with water pressure greater than 43.5 PSI (3 Bars).
CAUTION
In case of overload, a continuous acoustic warning signal will sound.
When the Acoustic Overload Warning is heard, it is recommended that the operating speed and ap-
plied pressure be immediately reduced, and /or, the core bit be operated under a no-load condition.
If the MK-2000P stops due to the activation of one of the overload protective devices, this
should not be considered an equipment failure.
