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.

PX-3 PAVER EXTREME SAFETY

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

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 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 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. Always disconnect the extension cord from the receptacle before disconnecting

the product from the extension cord.

WARNING

To choose the proper extension cord:

•

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

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.

PX-3 PAVER EXTREME SAFETY

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.

•

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 2. The tool has a grounding plug that looks like the plug illustrated in Sketch A of Figure 2. 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 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.
