MK-1080 PAVER SAW SAFETY
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 ad-
dition, 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.
SILICA DUST WARNING
CALIFORNIA PROPOSITION 65 MESSAGE
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-
tain 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 and 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/consilic.html
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 those dust masks that are specially designed to lter out microscopic particles.

To choose the proper extension cord:
ELECTRIC MOTOR SAFETY
For maintenance care and operation of the electric motor, refer to your electric motor instruction booklet
furnished with the electric motor. Protect the electric motor from dust as much as possible and keep
ventilating openings clean.
• DONOT spray water on the electric motor. Do not touch the plug with wet hands. To
reduce the risk of electrocution, keep all connections dry and off the ground.
• DONOT operate electric motor in an explosive environment.

WARNING
Use only extensions cords that are intended for outdoor use. These extension cords are identied
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 dam-
aged 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. Always disconnect the extension cord
from the receptacle before disconnecting the product from the extension cord.
WARNING
• Locate the length of extension cord needed
in table to the right.
• Once the proper length is found, move
down the column to obtain the correct
AWG size required for that length of
extension cord.
Use of undersize 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 customers expense. There will be no warranty claim.
Electric Motor Connection
ALWAYS make certain that the power source required for the electric motor is correct and always
use the correct NEMA conguration 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. See the table below.

MK-1080 PAVER SAW SAFETY
In order to prevent potential electrical shock and injury, the following electrical safety precautions and
symbols should be followed at all times!
In case of a malfunction or breakdown, grounding provides a path of least resistance for electric cur-
rent to reduce the risk of electric shock. This tool is equipped with an electric cord having an equip-
ment-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.
ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS
WARNING
• Do not modify the plug provided – if it will not t the outlet; have the proper outlet installed by a
qualied 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 qualied 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 of
Figure 1. The tool has a grounding plug that looks like the plug illustrated in Sketch A of Figure 1. A
temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to con-
nect this plug to a 2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not avail-
able. The temporary adapter should be used only until a properly grounded outlet can be installed by
a qualied 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.
