MANTA CORE DRILL III SAFETY

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 ad­dition, 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 and §1503.1).
Visit http://www.osha.gov for more information.

CALIFORNIA PROPOSITION 65 MESSAGE

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con­tain 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

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.

MANTA CORE DRILL III FEATURES

MK-MANTA III CORE DRILL

The MK-Manta III Core Drill is a powerful all-purpose drilling rig that is designed to drill holes, up to 12
inches in diameter (14 inches with the 2 inch spacer), in all types of concrete slabs, oors, walls, and
ceilings. The MK-Manta III Core Drill is designed for easy anchoring using masonry anchors. A vacuum
pump is provided to facilitate quick and easy anchoring to smooth oor surfaces.

MOTOR

The MK-Manta III Core Drill is designed for use with a variety of motors. All motors are powerful two or
three speed units that provide the correct cutting speed over a range of diamond drill sizes.

CARRIAGE, COLUMN AND BASE

The carriage, column and base assembly of the MK-Manta III Core Drill is the strong, sturdy drilling
platform that provides the rigidity needed to quickly drill accurately placed, straight, smooth holes in
all types of concrete. The MK-Manta III’s base is slotted to provide easy anchoring of the drill, in a
variety of drilling situations, with a single masonry anchor. The slot also allows more than one hole
to be drilled from a single anchor location. The base contains four leveling screws to insure accurate
hole alignment even on uneven concrete surfaces. The carriage also has a handle and the base has
6” wheels to provide easy transport. The carriage travel is controlled by a strong rack and pinion gear­system, that can be locked at any point on the column. The single spoked sliding handle allows that
operator to easily control the drilling pressure and speed. At the top of the column is a strong jack­screw that allows for additional bracing to overhead or opposite surfaces.

VACUUM PUMP

The vacuum pump provides quick and reliable mounting to smooth concrete slab and oor surfaces.
The powerful vacuum pump provides 25 PSI of holding power which equates to over 1800 pounds of
force, holding the MK-Manta III Core Drill securely, for safe, accurate drilling. The pump has a quick
disconnect connector on the hose at the base.

WATER SYSTEM

The water system for the MK-Manta III Core Drill is a simple hose hook-up and shut-off valve that pro­vides water under pressure to the diamond drill bit. The water travels to the center of the bit through
the water swivel and spindle to insure that water is supplied to the cutting end of the bit, even is deep
drilling operations.

MANTA CORE DRILL III OPERATION

Final Assembly

Plug the cord from the motor into the upper outlet on the meter box (the one opposite the motor on-off
switch). The other outlet on the meter box is for use with the vacuum pump.

DRILLING OPERATIONS

Electrical Requirements

The MK-Manta III Core Drill rig has been equipped with a Milwaukee motor. The drill should be used
on an electrical circuit, separate from other loads, and protected by a 30 amp circuit breaker. the MK­Manta III Core Drill has been provided with a 20 Amp plug (NEMA 15-20) or a 30 Amp (NEMA 15-30)
locking plug depending on the model.

Grounding

The MK-Manta III Core Drill is marked “Grounding Required” and has a three wire cord and three
prong grounding plug. The plug must be connected to a properly grounded outlet (see gure below).
If the tool should electrically malfunction or break down, grounding provides a low resistance path to
carry electricity away from the user, reducing the risk of electrical shock.

The grounding prong in the plug is connected through the green wire inside the cord to the grounding
system in the tool. The green wire in the cord must be the only wire connected to the toll’s grounding
systems and must never be attached to an electrically live terminal.

Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance
with all codes and ordinances.

WARNING

Improperly connecting the grounding wire can result in the risk of elec­tric shock. Check with a qualied electrician if you are in doubt as to
whether the outlet is properly grounded. Do not modify the plug pro­vided with the tool. Never remove the grounding prong from the plug.

EXTENSION CORDS

Do not use the tool if the cord or plug is damaged. IF damaged, have it repaired by an authorized
service facility before use. If the plug will not t the outlet, have a proper outlet installed by a qualied
electrician. The use of a circuit protected by a ground fault interrupter (GFCI) is highly recommended.

Use extension cords of the proper cable size, referring to the following chart.
