CDM1H HAND-HELD CORE DRILL — SILICOSIS 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.
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.

CDM1H HAND-HELD CORE DRILL — RULES FOR SAFE OPERATION
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.
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 force your core drill. Excerting excessive force while drilling will damage your machine and is hazardous.
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 test the 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.

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.
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 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 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.
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.

Drilling With Standard DRY/WET Core Bits
With the proper adapter, 1" to 3" diameter dry/wet core bits can be used with the CDM1H when drilling vertical and horizontal holes. All hand-held core drills require practice and operator technique to ensure consistent clean drilled holes. When using wet core bits, water MUST be used to ensure proper cooling. “Bit chatter” around the hole can be eliminated by various techniques such as angle-entry procedures and fabricated guides. Angle-entry is one safe and simple way to start the bit onto the surface. Angle the bit (1) at 10°-15° above the surface and slowly introduce the bit until it is flush with the surface (2). See Figure 5.

Drilling with a MQ Cobra™ Bit
The drilling of clean holes with Cobra™ core bits (1) requires an operating technique utilizing the center drill bit adapter (2). Center drill bit adapters are included with the core bit. As bits wear out, this adapter may be used with future core bits of similar depth and diameter. The adapter bit permits an anchoring point (3) so the bit can be accurately introduced into the surface (4). Once the hole is started, the center drill bit adapter (2) must be removed. See Figure 4.

2. If water is not flowing, check all connections and correct the problem.
3. Place the core drill against the surface (Figures 9 and 10) to be drilled. Hold drill firmly, and squeeze the power ON/OFF switch to begin drilling.
Warning - Binding of Output Shaft
ALWAYS drill with uniform pressure and keep
the bit straight. When drilling through steel rebar, reduce the pressure to avoid overloading the motor.
NEVER use the adjustable shoulder stock to pull the bit out of the ground if the bit gets stuck in the hole.
Figure 11. Wall Drilling Application
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 be on the lookout for exposed wiring or buried electrical connections when drilling.

CDM1H HAND-HELD CORE DRILL — SHUTDOWN/MAINTENANCE
Shutdown
1. Remove the power cord from the wall receptacle or power
source.
2. Allow a sufficient amount of time for the core drill bit to cool
before attempting to remove it from the core drill.
3. Using the wrenches as illustrated in Figure 4, remove the
core drill bit from the drill.
4. Clean the drill bit with a mild cleaning solution, removing
dirt and foreign matter.
5. Once the core drill has been cleaned, place the core drill
into its carrying case along with all associated hardware. Be sure to wrap the power cord neatly into the carrying case. This will extend the life of the cord.
6. Store the carrying case out of the reach of children, in a
location that is moisture free.
Maintenance
1. The CDM1H basically is maintenance-free. The only
maintenance requirement is to periodically check the main gear grease level.
2. Using the supplied 5 mm allen wrench, remove the grease plug as shown in Figure11.
3. Visually inspect to see if grease is present. It may be necessary to insert a small blade screw driver or similar device into the filler hole to determine if the grease level is low.
4. If the grease level is low, apply 1 shot of
grade N0.1. DO NOT over fill.
5. Reinstall grease plug and tighten securely.
