MK-101 Pro24 SAFETY
ALWAYS place the power ON/OFF switch in the OFF position when the saw is not in use.
ON / OFF
MAKE THE WORKSHOP KID PROOF
Make the workshops kid proof by using padlocks, master switches or by removing starter keys.
DO NOT FORCE THE TOOL
A power tool will do a job better and safer operating at the rate for which it was designed.
USE THE RIGHT TOOL
DO NOT force a tool or an attachment, to do a job that it was not designed to do.
USE THE PROPER EXTENSION CORD
If using an extension cord make sure it is in good condition rst. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. An under-
sized cord will cause a drop in line voltage that will result in a loss of power and overheating.
Page 9 shows the correct AWG size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier
the cord.
USE PROPER APPAREL
DO NOT wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may be
caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to
contain long hair.
SECURE WORK
Clamps or a vise should be used to hold work whenever practical. Keeping your hands free
to operate a power tool is safer.
DO NOT OVERREACH
Keep proper footing and balance at all times by not overreaching.
MAINTAIN TOOLS WITH CARE
Keep tools clean for the best and safest performance. Always follow maintenance instruc-
tions for lubricating, and when changing accessories.
DISCONNECT TOOLS
Power tools should always be disconnected before servicing or when changing accessories,
such as blades, bits, cutters, and the like.
KEEP CHILDREN AWAY
All visitors and children should be kept a safe distance from work area.
ALWAYS wear approved respiratory, head, ear and eye protection
when operating this machine.

MK-101 Pro24 SAFETY
NEVER LEAVE A TOOL UNATTENDED
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 nished.
NEVER STAND ON THE TOOL
Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally con-
tacted.
CHECK FOR DAMAGED PARTS
Before using a power tool, check for damaged part. A guard or any other part that is damaged
should be carefully checked to determine if 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.
Consult the owner’s manual for recommended accessories. Using improper accessories
may increase the risk of personal or by-stander injury. Unauthorized equipment
modifications will void all warranties. Manufacturer does not assume responsibility for any
accident due to equipment modifications.
USE RECOMMENDED ACCESSORIES
ALWAYS ensure that the machine is on level ground before using.
When loading or unloading the machine, use caution. Remove the blade prior to hoisting,
loading and transporting the machine.
TRANSPORT
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.
DIRECTION OF ROTATION
NEVER disconnect any "emergency or safety devices". These devices are intended for
operator safety. Disconnection of these devices can cause severe injury, bodily harm, or
even death! Disconnection of any of these devices will void all warranties. Unauthorized
equipment modifications will void all warranties. Manufacturer does not assume
responsibility for any accident due to equipment modifications.
NEVER operate this equipment when not feeling well due to fatigue, illness or taking medicine.
Check the chemical properties of the material to be cut/grinded and follow all EPA/OSHA
Regulations.

Sawing and drilling generates dust. Excessive airborne particles may cause irritation to eyes, skin
and respiratory tract. To avoid breathing impairment, always employ dust controls and protection
suitable to the material being sawed or drilled; See OSHA (29 CFR Part 1910.1200).
WARNING
MK-101 Pro24 SAFETY
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 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, 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
equipment, such as the 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
collection, use an industrial vacuum cleaner.

MK-101 Pro24 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.
• 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
This tool is intended for use on a circuit that has an outlet that looks like the one shown in Sketch A.
The tool has a grounding plug that looks like the plug illustrated in Sketch A. 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 electri-
cian. 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.

Drip Loop Information
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 discon-
nect. Keep cords away from heat and sharp edges. Always disconnect the extension cord
from the receptacle before disconnecting the product from the extension cord.
WARNING
Use of under sized extension cords result in low voltage to the motor that can result in mo-
tor 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.
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch
the plug with wet hands.

The “drip loop” is that part of the cord below the level of the receptacle,
or the connector, if an extension cord is used. This method of position-
ing 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. Discon-
nect the fuse or circuit breaker that supplies power to the tool. Then
unplug and examine for presence of water in the receptacle.
