WARNING
NEVER use this machine with any cutter designed for wood working.
MK-2000 ELECTRIC SAW SAFETY
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 voltage 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.
 1(9(5 lubricate components or attempt service on a running machine.
 Keep the machinery in proper running condition.
 Before using a power tool, check for damaged parts. A guard or any other part that is damage
should be carefully checked to determine if it would operate properly and perform its intended
function. Always check moving parts for proper alignment or binding. Check for broken parts and
mountings and all other conditions that may affect the operation of the power tool. A guard, or any
damaged part, should be properly repaired or replaced.

SILICA DUST WARNING
MK-2000 ELECTRIC SAW SAFETY
Wear eye protection.
Disconnect saw before servicing, when changing cutting blades and cleaning.
Replace damaged cutting blade before operation.
Remove adjusting keys and wrenches.
SAW SAFETY
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 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.
Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks
or surgical masks without a NIOSH approval number are not recommended because they do little to
protect the worker. For more information about respirator programs, including what respirators have
received NIOSH approval as safe and effective, please visit the NIOSH website at:
http://www.cdc.gov/niosh/npptl/topics/respirators
Observe OSHA regulations for respirator use (29 C.F.R.§1910.134 and §1503.1).
Visit http://www.osha.gov for more information.
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/docs/96-112/
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

Where use of a dust extraction device is possible, it should be used. To achieve a high level of dust collection, use an
industrial vacuum cleaner.

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.

 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

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
