SAW SAFETY

WARNING

MK-1080 PAVER SAW SAFETY

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.

SILICA DUST 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 and 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/consilic.html

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 those dust masks that are specially designed to lter out microscopic particles.

To choose the proper extension cord:

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.

• 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

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 dam-

aged 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 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.

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 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. See the table below.

MK-1080 PAVER SAW 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 cur-

rent to reduce the risk of electric shock. This tool is equipped with an electric cord having an equip-

ment-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

temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to con-

nect this plug to a 2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not avail-

able. 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.
