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.
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 trigger switch; locking button is in the RELEASE 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
Table of Contents
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 trigger switch, locking button is in
the "RELEASE" 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
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 a damaged or worn cord immediately
Grounding
(C)
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,

NOTE: Use of a temporary adapter is not permitted in Canada.
FIGURE 1
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 Brick 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.

SAFETY
Tool
Table of Contents
To avoid the possibly of the appliance plug or receptacle getting wet, position the Brick 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.
Power
Cord
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.
Drip Loop
Power
Supporting
Surface
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.
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.
