DAMAGE PREVENTION AND INFORMATION
MESSAGES:
A Damage Prevention Message is to inform the user
of important information and/or instructions that
could lead to equipment or other property damage if
not followed. Information Messages convey
information that pertains to the equipment being
used. Each message will be preceded by the word
NOTE, as in the example below.
NOTE:
Equipment and/or property damage may result if
these instructions are not followed.
GENERAL SAFETY PRECAUTIONS AND
HAZARD SYMBOLS:
In order to prevent injury, the following safety
precautions and symbols should be followed at all
times!
Safety Precautions:
KEEP GUARDS IN PLACE.
In order to prevent injury, keep guards in
place and in working order at all times.
REMOVE ADJUSTING KEYS AND WRENCHES.
Form a habit of checking to see that keys and
adjusting wrenches are removed from the power
tool before it is turned on.
KEEP WORK AREA CLEAN.
Cluttered work areas and benches invite accidents.
DO NOT USE IN DANGEROUS ENVIRONMENTS.
Do not use power tools in damp or wet locations nor
expose them to rain. Always keep the work area
well lighted.
KEEP CHILDREN AWAY.
All visitors and children should be kept a safe
distance from work area.
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 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 7 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.

SAFETY
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.
Make sure the ON/OFF Switch is in the OFF
position before plugging in a power tool.
Hazard Symbols:
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.
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!
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:
Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contain 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 and
• Arsenic and chromium, from chemically treated
lumber
For further information, consult the following
sources:
http://www.osha-
slc.gov/sltc/silicarystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLst
A.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 those dust masks that are
specially designed to filter out microscopic particles.

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
To reduce the risk of electrocution, keep
all connections dry and off the ground.
A Ground Fault Circuit Interrupter (GFCI) should be
provided on the circuit(s) or outlet(s) to be used for
the Saw. Receptacles are available having built-in
GFCI protections and may be used for this measure
of safety.
When using an extension cord, the GFCI should be
installed closest to the power source, followed by
the extension cord and lastly, the saw.
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 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
qualified electrician. 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.
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 the connector, if an
extension 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.

SAFETY
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.
