SAFETY WARNINGS
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.
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 and cement and other masonry products
• Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:
http://www.osha.gov/SLTC/silicacrystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.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.

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.
CAUTION
•DONOT 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.
•DONOT operate electric motor in an explosive environment.
WARNING
Use only extensions cords that are intended for outdoor use. These extension cords are identied 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. Always disconnect the extension cord from the receptacle before disconnecting
the product from the extension cord.
Electric Motor Connection
ALWAYS make certain that the power source required for the electric motor is correct and always use the
correct NEMA conguration 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.
To choose the proper extension cord:
•
Locate the length of extension cord needed in
table to the right.
•
Once the proper length is found, move down the

WARNING
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.

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 t the outlet; have the proper outlet installed by a qualied
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 qualied 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 2. The tool has a grounding plug that looks like the plug illustrated in Sketch A of Figure 2. 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 qualied 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.

PX-3 PAVER EXTREME SAFETY
WARNING
To reduce the risk of electrocution, keep all connections dry and off the ground.
A Ground Fault Circuit Interrupter (GFCI) should be provided on the circuit(s) or outlet(s) to be used for this
machine. Receptacles are available having built-in GFCI protections and may be used for this measure of safety.
When using an extension cord, the GFCI should be installed closest to the power source, followed by the
extension cord and lastly, the machine.
WARNING
The pump requires a GFCI. To reduce risk of electric shock when operating the machine with the pump
plugged into the 3-pole receptacle on the motor, connect the saw to a GFCI outlet. See the pump manual and
informational tags enclosed separately for all pump information.
WARNING
To avoid the possibility of the appliance plug or receptacle getting wet, position the machine to one side of
a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A “drip loop,”
shown in Figure 3, should be arranged by the user to properly position the power cord relative to the power source.
The “drip loop” is that part of the cord below the level of the receptacle, or the connector, if an extension
cord is used. This method of positioning the cord prevents the travel of water along the power cord and
coming in contact with the receptacle.
If the plug or receptacle gets wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that
supplies power to the tool. Then unplug and examine for presence of water in the receptacle.
