MK-5000 SAFETY
Before using a power tool, check for damaged parts. A guard or any other part that is
damaged 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. Always check the machine for loose bolts before starting.
A blade or cutter should always be installed so that rotation is in the direction of the
arrow imprinted on the side of the blade or cutter. It should correspond with the rotational
direction of the motor. Always feed work into a blade against the direction of rotation.
TURN POWER OFF - Do not leave a tool until it comes to a complete stop. ALWAYS
turn a power tool OFF when leaving the work area, or, when a cut is finished.
NEVER LEAVE A TOOL UNATTENDED
CHECK FOR DAMAGED PARTS
DIRECTION OF ROTATION
NEVER disconnect any "emergency or safety devices". These devices are intended for

CALIFORNIA PROPOSITION 65 MESSAGE
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 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/topics/respirators
Observe OSHA regulations for respirator use (29 C.F.R.§1910.134).
Visit http://www.osha.gov for more information.
MK-5000 SAFETY
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
http://www.P65warnings.ca.gov
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 dust masks that are specially designed to lter out microscopic particles. Where
use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec-
tion, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.

ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS
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.
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 similar to the one shown in
Sketch B of Figure below. The tool has a grounding plug that looks similar to the plug illustrated in
Sketch A of Figure below. Make sure the tool is connected to an outlet having the same conguration
as the plug. No adapter is available or should be used with this tool. If the tool must be reconnected
for use on a different type of electric circuit, the reconnection should be made by qualied service
personnel; and after reconnection, the tool should comply with all local codes and ordinances.
If permanently connected, this tool should be connected to a grounded metal permanent wiring sys-
tem; or to a system having an equipment-grounding conductor.
NOTE: Use of a temporary adapter is not permitted in Canada.

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 the picture below, 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 exten-
sion 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
Use only extension 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. Keep cords away from heat and sharp edges.
Always disconnect the extension cord from the receptacle before disconnecting the
product from the extension cord.
