MK-SCARIFIER SAFETY
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.
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.

MK-SCARIFIER SAFETY
Gasoline is extremely ammable, its vapors can explode if ignited; store only in approved
containers, in well-ventilated, unoccupied buildings and away from sparks or ames. DO
NOT ll the fuel tank while the engine is running or hot. Spilled fuel could ignite if it con-
tacts hot parts or sparks from ignition. DO NOT overll tank. DO NOT start the engine near
spilled fuel. Never use gasoline as a cleaning agent.
Gasoline models are shipped from the factory dry, meaning without fuel or oil. Both must be added
before equipment can be used. Check the engine Manufacturer Owner's Manual for instructions on
fueling, break-in, servicing and proper engine care and use.
Refer to engine manufacturer manual for specic operating procedures and safety warnings.
ALWAYS check the fuel lines and fuel tanks for leaks and cracks before starting the engine.
DO NOT run the machine if fuel leaks are present or the fuel lines are loose.
Accidental start hazard. Disconnect spark plug prior to servicing.
EXPLOSIVE FUEL!
GAS SAFETY PRECAUTIONS
GAS ENGINE SAFETY
Engine exhaust gasses contain poisonous carbon monoxide (an odorless, colorless gas).
Avoid inhaling exhaust fumes Breathing it can cause unconsciousness and even kill you.
Always operate gasoline engine machines in a well-ventilated area. DO NOT operate in ar-
eas where exhaust fumes could accumulate without wearing appropriate respiratory protec-
tion. Never run the engine in a closed building or conned area.
LETHAL EXHAUST GASES!
ALWAYS rell fuel tank in a well-ventilated area.
ALWAYS replace the fuel tank cap after refueling.
ALWAYS close fuel value on engines when machine is not being operated.
FUELING SAFETY
ALWAYS use caution when handling fuel. Shut off the engine and allow to cool before refueling.
Move the machine at least 10 feet (3 meters) from the fueling point before starting the engine, and
make sure the gas cap is on the machine and the fuel can is properly tightened.

MK-SCARIFIER SAFETY
WARNING
In order to prevent 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 electrical
current to reduce the risk of electric shock. This tool is equipped with an electric cord which has 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.
• 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.

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, GFCI should be installed closest to the power
source, followed by the extension cord and lastly, the machine.
ON
(
(
)
)
DO NOT abuse the cord. Never use the cord to carry the equipment or to pull the plug from
the outlet. Keep the cord away from heat, sharp edges, and moving parts. Replace dam-
aged cords immediately. Damaged cords increase the risk of electric shock.
ON
(
(
)
)
WARNING
Use only extension 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 dis-
connect. Keep cords away from heat and sharp edges. Always disconnect the extension cord
from the receptacle before disconnecting the product from the extension cord.
ON
(
(
)
)
ON
(
(
)
)
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.
WARNING
Use of undersized 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 customer’s expense. There will be no warranty claim.
To choose the proper extension cord,
• Locate the length of extension cord needed in the table below.
• Once the proper length is found, move down the column to obtain the correct
AWG size required for that length of extension cord.
