CDM1H HAND-HELD CORE DRILL — SILICOSISWARNING  
WARNING WARNING  
SILICOSIS WARNING  
RESPIRATORY HAZARDS  
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.  
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.

DANGER  
materials.The electric motor of this core-  
drill emits sparks during operation and  
shut-down. A explosion or fire could result  
causing severe bodily harm or even death if the sparks  
make contact with combustibe or explosive materials.  
Failure to follow instructions in this manual may lead to  
serious injury or even death! This equipment is to be  
operated by trained and qualified personnel only! This  
equipment is for industrial use only.  
Maintain this equipment in a safe operating condition at  
all times.  
Keep bystanders, children and vistors away while

equipment before reading this entire  
manual.  
This equipment should not be operated  
by persons under 18 years of age.  
NEVER operate this equipment without proper protective  
clothing, shatterproof glasses, steel-toed boots, hard hat  
and other protective devices required by the job.  
ALWAYS be sure the operator is familiar with proper  
safety precautions and operation techniques before using  
core drill.  
ALWAYS keep work area clean and free of foreign matter  
and debris. Also keep work area well lit.  
NEVER operate this equipment when not feeling  
well due to fatigue, illness or taking medicine.  
Avoid accidental starting. Make sure power ON/OFF  
switch is off before applying power. Carrying the core-  
drill with your finger on the power switch invites accidental  
starting.  
NEVER operate this equipment under the influence of  
drugs or alcohol.  
NEVER leave the core drill unattended.When not in use  
always unplug the core drill from power source.  
ALWAYS remove any adjusting keys or wrenches before  
turing the core drill on. A wrench or key that is left attached  
to the rotating part of the core drill may result in personal  
injury.  
DO NOT overreach. Keep proper footing and balance at  
all times. Proper footing and balance enables better  
control of the core drill in unexpected situations.  
ALWAYS wear proper respiratory (mask),  
hearing and eye protection equipment when

CDM1H HAND-HELD CORE DRILL — RULES FOR SAFE OPERATION  
DO NOT walk around with a plugged in core drill. The  
possibility exist of your finger accidently hitting the power  
ON/OFF switch, causing severe bodily harm or even  
death.  
Maintain the core drill and drill bits with care. Keep drill  
bits sharp. Sharp cutting edges are less likely to bind.  
If drilling into a workpiece that is unattached, use clamps  
or other means to secure the workpiece so that it will not  
move. NEVER hold the workpiece by hand or againist  
your body.  
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 core-  
drill.  
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.  
NEVER point the core drill at anyone in the area when  
operating.  
ALWAYS hold the core drill firmly with both hands when  
drilling.  
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 expose the the core drill to rain or wet conditions.  
Water entering the drill wii increase the risk of electrical  
shock.  
DO NOT force your core drill. Excerting excessive force  
while drilling will damage your machine and is hazardous.  
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 hold core drill by its insulated gripping handle  
when performing work. The possibility exists of the drill  
bit making contact with hidden wiring or its own cord.  
Contact with a "live" wire can cause electrical shock to  
the operator.  
ALWAYS make sure drill bits are installed securely so  
that it will 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 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 accendental starting.  
ALWAYS test the ON/OFF switch on the core drill before  
operating. The purpose of this switch is to shut down the  
electric motor.  
NEVER use a extension cord that is frayed or damaged  
where the insulation has been cut.  
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 4.  
NEVER allow power cord to lay in water.  
NEVER stand in water while operating the core drill.

EMERGENCIES  
TRANSPORTING  
ALWAYS know the location of the nearest fire  
extinguisher and first aid kit.  
ALWAYS place the core drill inside its carrying case when  
work has been completed.  
ALWAYS wrap power cord neatly to avoid damage.  
ALWAYS place wrenches back into carrying case when  
work has been completed.  
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.  
In emergencies always know the location of the  
nearest phone or keep a phone on the job site.
