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 filter out microscopic particles.

CAUTION must be observed while servicing the machine. Rotating parts can cause injury if contacted.
Ensure that any electrical extension cord is protected against damage. Always ensure that the electrical
extension cord is not trapped underneath the machine.When using an extension cord, be sure to use one
heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line volt-
age that will result in a loss of power and overheating. The Table shown on page 9 shows the correct AWG
size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heaviest gage.
The smaller the gage number, the heavier the cord.
DO NOT allow extension cord to come into contact with water or fluids. DO NOT spray water onto electric motor.

TX-3 SAFETY
•NEVER stand on the tool. Serious injury could occur if a power tool is tipped, or if a cutting tool is
unaintentionally contacted.
•Become familiar with the controls of the machine before operating. Know how to stop the machine quickly
in case of emergency.
•ALWAYS secure work. Clamps or a vise should be used to hold work whenever practical. Keeping your
hands free to operate a power tool is safer.
•ALWAYS disconnect AC power plug from power source before moving, cleaning or servicing the
machine.
•NEVER leave a tool running unattended. Do not leave a tool until it comes to a complete stop.
A LWAYS turn a power tool OFF when leaving the work area, or when a cut is finished.
•Make sure the OFF/ON power switch on the electric motor is always in the OFF position before
inserting the machine’s power plug into an AC receptacle.
•Operate electric motor only at the specified voltage indicated on the nameplate.
•NEVER disconnect any “emergency or safety devices”.These devices are intended for operator safety.
Disconnection of these devices can cause severe injury, bodily harm or even death! Disconnection
of any of these devices will void all warranties.
•Unauthorized equipment modifications will void all warranties. Manufacturer does not assume responsibility
for any accident due to equipment modifications.

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.
Electric Motor Connection
A LWAYS make certain that the power source required for the electric motor is correct and always use the
correct NEMA configuration plug. Motors can burn out when the line voltage falls 10% below the voltage rat-
ing 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.
•
•
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.
CAUTION
NOTICE
Most Motor Problems are caused by improper
voltage and extension cords. Cord should be
one-piece and short as possible. Cord
selection should match the following table.

WARNING
Use only extensions cords that are intended for outdoor use. These extension cords are identified 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.
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 pre-
mature 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.

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 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.

TX-3 SAFETY
ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS
WARNING
Do not modify the plug provided – if it will not fit the outlet; have the proper outlet installed by a qualified
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 qualified 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 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 qualified 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.
