SAFETY
USE THE PROPER EXTENSION CORD.
If using an extension cord make sure it is in good condition first. 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. TABLE 1, Page 8 shows the correct AWG
size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord.
WEAR 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.
ALWAYS USE SAFETY GLASSES.
Safety glasses should always be worn when working around power tools. In addition, a face,
dust mask or respirator should be worn if a cutting operation is dusty. Everyday eyeglasses only
have impact resistant lenses and may not prevent eye injury-they are NOT safety glasses.
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 instructions 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.
REDUCE THE RISK OF UNINTENTIONAL STARTING.
on Make sure the ON/OFF switch is in the OFF position before plugging in a power tool.
USE RECOMMENDED ACCESSORIES.
Consult the owner's manual for recommended accessories. Using improper accessories may increase the
risk of personal or by-stander injury.
NEVER STAND ON THE TOOL.
Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally contacted.
CHECK FOR DAMAGED PARTS.
Before using a power tool, check for damaged parts. A guard or any other part that is damaged should be
carefully checked to determine 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.
DIRECTION OF FEED.
Always feed work into a blade or cutter against the direction of rotation. A blade or cutter should always be
installed such that rotation is in the direction of the arrow imprinted on the side of the blade or cutter.
NEVER LEAVE A TOOL RUNNING 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 finished.

SAFETY
Hazard Symbols:
ELECTRICAL SHOCK!
Never touch electrical wires or components while the motor is running. Exposed, frayed or worn
electrical motor wiring can be sources of electrical shock that could cause severe injury or burns.
ACCIDENTAL STARTS!
on Before plugging the equipment into an electrical outlet, be sure the ON/OFF switch is in the OFF
position to prevent accidental starting. Unplug the power tool before performing any service operation.
ROTATING OR MOVING PARTS!
Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate a
power tool with covers, shrouds, or guards removed.
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). Diamond Blades improperly used are
dangerous. Comply with American National Standards Institute Safety Code, B7.1 and, Occupational Safety
and Health Act covering Speed, Safety Guards, Flanges, Mounting Procedures, General Operating Rules,
Handling, Storage and General Machine Conditions.
CALIFORNIA PROPOSITION 65 MESSAGE:

SAFETY
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
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 fit the outlet; have the proper outlet installed by a
qualified 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 qualified 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

Power
Cord
To avoid the possibility of the appliance plug or receptacle getting wet, position the saw to one side
of a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A
"drip loop," shown in FIGURE 2, 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
Power
Tool
the connector, if an extension cord is used. This method of positioning the
Supporting
Surface
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.
Drip Loop
FIGURE 2
Use only extensions 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 disconnection the
product form the extension cord.
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the
plug with wet hands.
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.
To choose the proper extension cord,
• Locate the length of extension cord needed in TABLE 1 below.
• Once the proper length is found, move down the column to obtain the correct AWG size required
for that length of extension cord.
As an example, a fifty (50) foot extension cord would require an AWG size of 16.

THEORY
THEORY OF DIAMOND BLADES:
Diamond blades do not really cut; they grind the material through friction. Diamond crystals, often visible at
the leading edge and sides of the rim/segment, remove material by scratching out particles of hard, dense
materials, or by knocking out larger particles of loosely bonded abrasive material. This process eventually
cracks or fractures the diamond particle, breaking it down into smaller pieces. As a result, a diamond blade
for cutting soft, abrasive material must have a hard metal matrix composition to resist this erosion long
enough for the exposed diamonds to be properly utilized. Conversely, a blade for cutting a hard, nonabrasive material must have a soft bond to ensure that it will erode and expose the diamonds embedded in
the matrix. These simple principles are the foundation of “controlled bond erosion”.
Types of Cutting:
There are two basic types of cutting-Dry or Wet. The choice of which type of blade to use depends on:
• The requirements of the job
• The machine/tool utilizing the diamond blade
• The preference of the operator
In the case of DRY cutting, the overwhelming popularity and quantity of hand-held saws and the flexible
nature of MK Diamond blades to professionally handle most ceramic, masonry, stone and concrete materials,
make the DRY cutting blade a very attractive tool. When using a DRY blade, the user must be aware of
distinct operating practices to ensure optimum performance. DRY cutting blades require sufficient airflow
about the blade to prevent overheating of the steel core. This is best accomplished by shallow, intermittent
cuts of the material with periods of “free-spinning” (for several seconds) between each cut, to maximize the
cooling process.
For WET cutting applications, MK has the exact blade to compliment both the material to be cut and the wet
cutting machine to be used. During cutting operations, liberal amounts of water act as a coolant to support
the cutting effectiveness and longevity of the WET blade. Additionally, using water adds to the overall safety
of cutting operations by keeping the dust signature down.
