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.
MK-212 SAW SAFETY

In order to prevent potential electrical shock and injury, the following electrical safety precautions and sym-
bols should be followed at all times!
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.
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 tempo-
rary 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 adapt-
er 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.

Receptacle
Power
Cord
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
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.
Shock Hazard. For replacement, use only an identical pump, model PE-1 part #151271.
NOTE: Do not run pump dry. Also, be sure to disconnect and remove the pump when cutting dry.
CAUTION
Fig. 2 Drip Loop Information
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 2,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.
WARNING

11
MK-212 SAW SAFETY
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 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 disconnection the product from 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 undersized extension cords result in low voltage to the motor that can result in motor burnout and
premature failure. Barranca 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 provided.
• Once the proper length is found, move down the column to obtain the correct AWG size required for
that length of extension cord.
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.
