MKDX 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.
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.

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.
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 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.

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.
CAUTION
Shock Hazard. For replacement, use only an identical MK pump, model PE-2H part #160509.
NOTE: Do not run pump dry. Also, be sure to disconnect and remove the pump when cutting dry.
When using the water pump plugged into the water pump receptacle, the machine must be plugged
into a properly installed and grounded GFCI outlet See Figure 2. If a GFCI outlet is not available,
MK Diamond has available as an accessory item, a plug-in GFCI that may be plugged into a properly
installed and grounded 3-pole outlet.
WARNING
Fig. 2 GFCI Outlet
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.

form the extension cord.
WARNING
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the
plug with wet hands.
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.
To choose the proper extension cord
• Locate the length of extension cord needed
in 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.
LOCK OUT METHOD
In order to help prevent accidental starting and
to help make your work area “kidproof,” this
machine is provided with a means to deactivate
the functioning of the motor switch. The switch
is equipped with a lockout tab that can be used
with a lock to prevent movement of the switch.
With the switch unable to move the motor cannot be turned on. Removing the lock reactivates
the switch.

MKDX OPERATION
SHAPING
WARNING
Before starting your shaping, make sure the wheel is sharp, correctly positioned and rmly in place.
WARNING
Before shaping, make sure the handles and clamps are rmly secured to the material slide. To
prevent material dislodging and motor overloading, the forward speed during the shaping must be
proportional to the hardness and thickness of the material to be shaped. A gentle pressure should be
applied. DO NOT force the piece through.
Shaping
1. Loosen spray guard knobs (Figure 38).
2. Move spray guard down so brush is touching material slide. Tighten down by turning knobs
(Figure 39).
3. Turn on machine and check water is spraying on shaping wheel. With material clamped tightly
in position and all adjustments made, place hands on handles as shown (Figure 40).
