DM15A9C/CDM2CSA — PROPOSITION 65 WARNING
DM15A9C/CDM2CSA — SILICOSIS WARNING 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.

DM15A9C/CDM2CSA— SAFETY MESSAGE ALERT SYMBOLS FOR YOUR SAFETY AND THE SAFETY OF OTHERS! Safety precautions should be followed at all times when operating this equipment. Failure to read and understand the Safety Messages and Operating Instructions could result in injury to yourself and others.
DM15A9C/CDM2CSA— RULES FOR SAFE OPERATION DANGER Read this manual! 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. The following safety guidelines should always be used when operating the MQ DM15A9C (electric motor) and CDM2SA (drill rig) GENERAL SAFETY ■ DO NOT operate or service this equipment before reading entire manual.
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.
DM15A9C/CDM2CSA— RULES FOR SAFE OPERATION 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.
DM15A9C/CDM2CSA — GENERAL INFORMATION APPLICATION Threads/Adapters The MQ DM-15A9C Stationary Core Drill Motor is designed to be used with the MQ CDM-2CSA Lightweight Drilling Rig. The core drill motor is intended only for wet drilling applications involving concrete type materials. Up to 9-inch (229 mm) diameter holes can be drilled for wet drilling applications using standard MQ wet drill bits. All MQ wet drill bits allow for a 14-inch cutting depth .
DM15A9C/CDM2CSA — GENERAL INFORMATION Operator Technique Water 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. Water acts as a coolant, eliminating the heat caused by the friction of the drilling.

DM15A9C/CDM2CSA— DRILL RIG COMPONENTS Figure 3 illustrates the basic componets of the MQ CDM2CSA Drill Rig. Shown below is breif explanation of each componet. Figure 3. CDM2CSA Drill Rig Components 1. 2. 3. 4. 5. Leveling Screws – Use these screws (4) to level the the drill rig. Base – Supports the column rack and associated components. Wheels – 2 rear wheels have been provided for ease of maneuverability.
DM15A9C/CDM2CSA — CORE DRILL MOTOR COMPONENTS Figure 4 illustrates the basic componets of the MQ DM15A9C Drill Rig. Shown below is breif explanation of each component. Figure 4. DM15A9C Core Drill Motor 1. 2. 3. 4. 5. 6. Speed Adjustment Knob – Use this knob to adjust the speed of the electric motor. Turn knob counterclockwise to loosen. Push knob toward shaft end to decrease motor speed. Pull knob back towards ON/ OFF switch to increase motor speed.
DM15A9C/CDM2CSA — PRE-SETUP Before Starting: Warning - Toxic Fumes CAUTION - Read Manual NEVER operate the core drill in a confined or enclosed area structure that does not provide ample free flow of air. Before attempting to operate this core drill, and to avoid serious injury to personnel, always read and understand operation manual. Failure to read and understand operation manual could result in serious harm or even death! 3.
DM15A9C/CDM2CSA — PRE-SETUP 5. Locate the cradle assembly (Figure 7) and place it directly over the column. Make sure the cradle handle is located on the right side of the column if you are standing at the back (wheels) of the drilling rig. It may be necessay to loosen the cradle tension knob slightly to allow the cradle to slip onto the column rack. 7. Once the cradle has been mounted onto the column rack, align the top plate (Figure 9) on the adjustment bar with the stud on the top of the column.
DM15A9C/CDM2CSA — PRE-SETUP Securing the Drill Rig Assembly Secure the Drilling Rig as follows: DANGER - Drill Rig Tipping DO NOT attempt to use this unit until it has been securely anchored to a suitable surface. The possibility exists of severe bodily harm and damage to the equipment if the core drill bit becomes stuck or binds thus causing the unit to tip over. This drilling rig can be secured by various methods. Please read the next few paragraphs to determine which method best suits your application.
DM15A9C/CDM2CSA — PRE-SETUP Method 2 incorporates drilling a hole 1/2-inch in diameter into the drill rig support surface (wall or floor), and inserting an expansion type anchor. 1. Using a masonry bit, drill a hole approximately ½-inch in diameter. When drilling the hole make sure it is approximately 200 mm away from center. See Figure 14.
DM15A9C/CDM2CSA — PRE-SETUP Attaching the Core Drill Motor to the Cradle Applying Power to the Core Drill 1. There may be an aluminum adapter plate (Figure 17) attached to the core drill motor. Remove this plate using a 6 mm allen wrench before attempting to secure the drill motor to the cradle. This adapter plate is intended to be used on other MQ drill rig stands. 2. The core drill motor can be secured to the cradle (Figure 17) by means of 4 retaing screws and lock washers.
DM15A9C/CDM2CSA — OPERATION Operation 1. Place the valve on the water source to the ON position, and then turn the water valve on the core drill (Figure 20) to the ON position (down). Verify that water is flowing smoothly and evenly. Turn the valve clockwise to increse water flow and counterclockwise to decrease water flow. Figure 20. Water Valve (ON Position) 2. If water is not flowing, check all connections and correct the problem. Water should be flowing at a rate of one or two gallons per minutes.
DM15A9C/CDM2CSA — SHUTDOWN Shutdown 1. Place the power ON/OFF switch on the core drill motor in the OFF position and unplug 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 motor. 3. Using the wrenches as illustrated in Figure 4, remove the core drill bit from the drill. 4. If desired remove the core drill motor from the cradle.
DM15A9C/CDM2CSA — MAINTENANCE Maintenance Lubrication Clutch Adjustment 1. Using a 5 mm allen wrench, remove the hex plug as shown in Figure23A.Figure 8. Wall Application 1. The DM15A9C electric motor is basically maintenance free. However, it may become necessary at some time to adjust the clutch. 2. Using a 5 mm allen wrench, remove the hex plug as shown in Figure 23A to gain acess to the clutch adjustment hole. 3.
DM15A9C/CDM2CSA — TROUBLESHOOTING TABLE 6. CORE DRILL TROUBLESHOOTING SYMPTOM Bit is stuck. Drilling is slow in normal operation. POSSIBLE PROBLEM SOLUTION Steel bar or stone, etc. is caught between core and bit?. Immediate turn SWITCH OFF. Excessive wear, bit tip has become flush with shank? Try to rotate BIT in both directions using spanner to lift it out. Glazed bit? Replace BIT. Waste water is contaminated with steel chip, DRILL is cutting rebar? Immediately check the waster water.
