DM15A9C/CDM2CSA — PROPOSITION 65 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 the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

DM15A9C/CDM2CSA — RULES FOR SAFE OPERATION
■
Maintain the core drill and drill bits with care. Make sure
bit maintains good diamond exposure. A dull bit will cause
glazing.
■
NEVER drill into a work piece that is not secured.
■
Use this core drill only for its intended purpose. DO NOT
use this core drill for applications not recommended.
■
Inspect the drill after each use. Replace any damaged or
worn parts immediately. DO NOT use a defective coredrill.
■
NEVER cover the air vents on the body of the core drill.
ALWAYS leave these vents exposed. These vents are
essential for the cooling of the electric motor. NEVER
place tape over the vent to keep out dust.
■
If a malfunction occurs, immediately unplug the core drill
from the power source and correct the problem. If the
problem can not be corrected, contact your nearest MQ
service center.
■
DO NOT force your core drill. Excerting excessive force
while drilling will damage your machine and is hazardous.
■
ALWAYS make sure drill bit is installed securely so that
it will not slip or fall out. It is hazardous to use a core drill
with a loose fitted drill bit.
■
Some materials contain chemicals which may be
toxic.Take precautions to prevent dust inhalation and skin
contact.
ELECTRICAL SAFETY
■
ALWAYS test the

electric motor.

■
When connecting the core drill to a power receptacle,
make sure the receptacle circuit is connected to either a
GFCI receptacle or a receptacle protected by a 20 amp
circuit breaker.
When plugging the core-drill into a power receptacle, check
the nameplate for the correct operating voltage. Operating
the core drill at the wrong voltage will damage the electric
motor. ALWAYS read the nameplate before applying
power.
This core drill is equipped with a 3-prong male power
plug. DO NOT use a 2-prong adapter when plugging into
a wall outlet. This will defeat the purpose of the ground
circuit. If the plug does not fit into the receptacle, contact
a qualified electrician to install a 3-conductor wall
receptacle (outlet).
Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased
risk of electrical shock if your body is grounded.
DO NOT expose the the core drill to rain or wet conditions.
Water entering the drill wii increase the risk of electrical
shock.
When operating the core drill outside, be sure to use the
apporpriate outdoor extension cord. This type of extension
cord reduces the risk of electrical shock.
ALWAYS be on the lookout for hidden wiring, the
possibility exists of the drill bit making contact with hidden
wiring. Contact with a "live" wire can cause electrical
shock to the operator.
ALWAYS remove the AC power cord from the power
source before performing any service or maintenance on
the core drill. This preventative safety measure reduces
the possibility of accidental starting.
■
NEVER carry the core drill by its power cord or disconnect
it by yanking the cord from the power outlet.
■
ALWAYS make certain that the proper extension cord
has been selected for the job. See Table 1.

TRANSPORTING
■
ALWAYS secure the core drill and drill rig with rope or
tie-downs when transporting is required.
■
ALWAYS wrap power cord neatly to avoid damage.
■
ALWAYS place wrenches in a safe location where they
can be located easily. Keep tools clean.
MAINTENANCE
■
NEVER lubricate components or attempt service on a
running core drill.
■
ALWAYS allow the core drill a proper amount of time to
cool before servicing.
■
Keep the core drill in proper running condition.
■
Fix damage to the core drill immediately and always
replace broken parts. Replace with only MQ
recommended parts.

Extension Cords
Use only 3-prong type extension cords with grounding pin. Always
connect extension cord to a matching 3-prong receptacle. NEVER
use a 3 to 2 prong adapter, this type of adapter will defeat the ground
circuit protection capability. Always use an extension cord of
adequate current carrying cability. Use Table 1 as a guidline when
selecting the proper extension cord.

DM15A9C/CDM2CSA — GENERAL INFORMATION
Operator Technique
Always drill with consistent uniform pressure. NEVER subject the
drill bit to sudden impacts. Uneven pressure can damage a bit. Slow
bit penetration leads to bit glazing. Excessive drill pressure can
overload the drill motor. Always try and let the drill bit do the work and
try not to force the bit through the material.
If vibration occurs while drilling do the following:
■
Stop drilling
■
Turn motor off
■
Check for loose nuts or bolts on the equipment
■
Check for bit runout. Replace if necessary
Drilling Performance
Factors that influence core drilling:
■
Amount of water flow
■
Condition of equipment
■
RPM of electric drill motor
■
Amount and size steel
■
Age of concrete
■
Aggregate (size, type, hardness, abrasiveness)
■
Operator technique
■
Bit runout
Water
Water acts as a coolant, eliminating the heat caused by the friction
of the drilling. This preserves the integrity of the drill bit. Without
water acting as a coolant, the heat buildup during drilling will greatly
reduce the life cycle of the drill bit.
During drilling water flushes loose, abrasive particles created during
drilling. These particles consist of aggregate, sand, and various
metals from embedded steel. The hole must be free of debris to
allow the core bit to work.
If loose particles are not properly flushed from the hole, an
unecessary drag will occur along the side of the core barrel. This
can contribute to bit glazing (less power) and damage to the electric
motor. In addition loose particles contribute to premature bit wear.
Monitor water flow continuously. Water volume should be adjusted
until water return is muddy. Clear streaks indicate too much water
volume. Excessive water volume is the leading cause of bit glazing.
Excessive water prevents adequate segment material contact. When
the bit segments do not make proper contact with the work surface
(hydro-planing) they begin to glaze. Adequate water volume varies
according to bit diameter. Use only enough water during drilling to
flush particles from the work surface.
Bit Glazing
Bit binding is caused by either a dull (glazed) bit or a poorly stabilized
drilling rig. The causes of glazing are as follows:
■
Wrong RPM for drill bit diameter
■
Excessive feed pressure
■
Low feed pressure
■
High steel content in material work surface
■
Large hard aggregate
■
Too much water
■
Low electric motor RPM's
