MK-212 SAW SAFETY
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).
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, 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 lter out microscopic particles. Where
use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec-
tion, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.
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 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.
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).

MK-212 SAW SAFETY
WARNING
In order to prevent electrical shock and injury, the following electrical safety precautions and symbols
should be followed at all times!
If permanently connected this tool should be connected to a grounded metal permanent
wiring system; or to a system having an equipment - grounding conductor.
In case of a malfunction or breakdown, grounding provides a path of least resistance for electrical
current to reduce the risk of electric shock. This tool is equipped with an electric cord which has 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 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.
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 qualied electri-
cian. The green-colored rigid ear, plug, and the like, extending from the adapter, must be connected
to a permanent ground, such as a properly grounded outlet box.

WARNING
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, GFCI should be installed closest to the power
source, followed by the extension cord and lastly, the machine.
The water pump requires a GFCI. To reduce risk of electrical shock when operating the machine
with the pump plugged into the 3-pole receptacle on the motor, connect the machine to a GFCI
outlet. See the pump manual and informational tags enclosed separately for all pump information.

let furnished with the electric motor. Protect the electric motor from dust as much as possible and keep
ventilating openings clean. Before plugging in the machine, make sure that the outlet voltage is within
the voltage marked on the machines's data plate.
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.
ELECTRIC MOTOR SAFETY
DO NOT operate electric motor in an explosive environment.

To avoid the possibility of the appliance or plug receptacle getting wet, position the machine to one
side of a wall mounted receptacle. This will prevent water from dripping into the receptacle or plug. A
"drip loop," shown in the picture below, should be arranged by the user to properly position the power
cord relative to the power source. Use the drip loop as a way to prevent GFCI and plug from getting
wet.
The "drip loop" is that part of the cord below the level of the receptacle (or the connector, if an exten-
sion 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.

WARNING
Use only extension 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 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 dis-
connect. 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 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.
