MK-1503SS 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).
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, 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 filter out microscopic particles. Where use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec-
WARNING
Sawing, grinding and drilling generate dust. Excessive airborne particles may cause irritation to eyes, skin and respiratory tract. To avoid breathing impairment, always employ dust controls and protection suitable to the material being sawed or drilled; See OSHA (29 CFR Part 1910.1200).

ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS
In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be followed at all times!
WARNING
In case of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
• Do not modify the plug provided – if it will not fit the outlet; have the proper outlet installed by a
qualified electrician
• Improper connections of the equipment-grounding conductor can result in a risk of electric
shock. The equipment-grounding conductor is the insulated conductor that has an outer surface
that is green, with or without yellow stripes. If repair or replacement of the electric cord or plug is
necessary, do not connect the equipment-grounding conductor to a live terminal
• Check with a qualified electrician or service personnel if the grounding instructions are not
completely understood, or if in doubt as to whether the tool is properly grounded
• Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that
accept the tool’s plug
• Repair or replace a damaged or worn cord immediately
WARNING
This tool is intended for use on a circuit that has an outlet that looks like the one shown in Sketch A.
The tool has a grounding plug that looks like the plug illustrated in Sketch A. A temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a
2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box.
NOTE: Use of a temporary adapter is not permitted in Canada.

MK-1503SS SAFETY
WARNING
The polisher requires a Ground Fault Circuit Interrupter (GFCI). To reduce the risk of electrocution, keep all connections dry and off the ground. A GFCI is provided as an integral part of the power cord for the tool. Receptacles are available having built-in GFCI protectors and may be used with this equipment. When using an extension cord, the GFCI in the power cord and extension cord connections need to be kept dry and off the ground.
WARNING
To avoid the possibility of the in-line GFCI getting wet, position it to the side of the work area. A “drip loop” shown in the picture below, should be arranged by the user to properly protect the GFCI.
The “drip loop” is that part of the cord below the level of the GFCI or the connector, if an extension cord is used. This method of positioning the cord prevents water traveling along the power cord, coming in contact with the GFCI, extension cord connections or receptacle.
If the GFCI, plug or receptacle get wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the tool. Then unplug and examine all components for presence of water.
NOTE: Drip Loop Information - Raise GFCI and plug off the floor with a cardboard carton or brick or other non-conductive support to prevent water from traveling along the power cord.

WARNING
Use only extension cords that are intended for outdoor use. These extension cords are identified by a marking "Acceptable for use with outdoor appliances; store indoors while not in use." Use only extension cords having an electrical rating not less than the rating of the product. DO NOT use damaged extension cords. Examine extension cords before using and replace if damaged. DO NOT abuse extension cords and DO NOT yank on any cord to disconnect. Keep cords away from heat and sharp edges. Always disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
ALWAYS make certain that the power source required for the electric motor is correct and always use the correct NEMA configuration plug. Motors can burn out when the line voltage falls 10% below the voltage rating of the motor. Failure to use proper voltage will cause the motor to overheat. Make certain that the correct size grounded (3-wires) extension cord is used.
WARNING
Use of undersized extension cords result in low voltage to the motor that can result in motor burnout and premature failure. MK Diamond warns that equipment returned to us showing signs of being run in a low voltage condition, through the use of undersized extension cords,will be repaired or replaced totally at the customer’s expense. There will be no warranty claim.
To choose the proper extension cord,
• Locate the length of extension cord needed in the table below.
• Once the proper length is found, move down the column to obtain the correct
AWG size required for that length of extension cord.

21
MK-1503SS THEORY
Polishing pads are designed to achieve a monument quality finish on all straight or shaped surfaces.
The unique design of the polishing pads allows for rapid and even surface removal rates of the material being polished with minimal effort. When used correctly, these pads provide a clear advantage over all other polishing methods.
Important Points in the Polishing Process
Polishing pads are designed for use with water only, to minimize the wear on the pads and prevent hazardous dust. Water acts to cool the polishing pad material, flush away grindings, and eliminate hazardous dust.
Never skip grit sizes during the polishing process. Skipping polishing pads of different grit sizes will result in an unsatisfactory finish to the polished surface.
Diamond polishing pads wear out prematurely due to the overworking of the material or by not using a sufficient amount of water. Failure to spend adequate time polishing with each grit size pad will result in an unsatisfactory finish.
Selection of the flexible Velcro™ (rubber) backer pads for shaping and curved work is highly recommended. Use the rigid backer pad for the straight edge and flat face material.
