Table of Contents

MK-145 Revision 1, Effective date –December 14, 2000 Page 5
SAFETY:
KEEP CHILDREN AWAY.
All visitors and children should be kept a safe distance from work area.
MAKE 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 a rate for which it was
designed
USE THE RIGHT TOOL.
Do not force a tool or attachment, to do a job that it was not designed to do.
USE THE PROPER EXTENSION CORD.
If using an extension cord, make sure its 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 9) 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. Nonslip 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 or dust mask 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.
Always keep proper footing and balance at all times by not overreaching.
MAINTAIN TOOLS WITH CARE.
Keep tools sharp and 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.

MK-145 Revision 1, Effective date –December 14, 2000 Page 6
SAFETY:
REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure the ON/OFF switch is in 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 TOOL.
Serious injury could occur if a power tool is tipped, or, if the cutting tool is
unintentionally contacted.
CHECK DAMAGED PARTS.
Before using a power tool, check for damaged parts. A guard or another 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, 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 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 finished cutting.
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!
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.

MK-145 Revision 1, Effective date –December 14, 2000 Page 7
SAFETY:
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
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.
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 damaged or worn cord immediately

MK-145 Revision 1, Effective date –December 14, 2000 Page 8
SAFETY:
This tool is intended for use on a circuit that has an outlet that looks like the one
shown in Sketch A, in Figure 1. The tool has a grounding plug that looks like the
plug illustrated in Sketch A, in FIGURE 1. A temporary adapter that 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 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 tile 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.
To avoid the possibly of the appliance plug or receptacle getting wet, position the
Tile 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 extension cords from the
receptacle before disconnecting the product form the extension cord.
Use of undersize extension cords results 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,
with undersized extension cord, 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.
