TX-3 SAFETY
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-slc.gov/sltc/silicarystalline/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.

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 11 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.
• NEVER operate the machine in an explosive atmosphere.
Before starting the machine, check that all guards are in position and correctly fitted.
Keep area around the machine clear of obstructions which could cause persons to fall onto moving parts.

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.

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.
TX-3 SAFETY
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.
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
Safety labels are located on the back of the motor assembly (figure 3). The labels contain important safety in-
formation. Please read the information contained on each safety label. These labels are considered a permanent
part of your saw. Should any of these decals become unreadable, replacements can be obtained by calling
[phone].
