SAFETY 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.
DAMAGE PREVENTION AND INFORMATION MESSAGES:
NOTE: Equipment and/or property damage may result if these instructions are not followed.
In order to prevent injury, the following safety precautions and symbols should be followed at all times!
GENERAL SAFETY PRECAUTIONS AND HAZARD SYMBOLS
SAFETY PRECAUTIONS
Form a habit of checking to see that keys and adjusting wrenches are removed from
the power tool before it is turned on.
Cluttered work areas and benches invite accidents.
DO NOT use power tools in damp or wet locations nor expose them to rain. Always
keep the work area well lighted.
All visitors and children should be kept a safe distance from work area.
A safety message alerts you to potential hazards that could hurt you or others. Each safety message is preced-
ed by a safety alert symbol ( ) and one of three words: DANGER, WARNING, or CAUTION.
DANGER You WILL be KILLED or SERIOUSLY INJURED if you do not follow directions.

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 10 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.
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.
Keep proper footing and balance at all times by not overreaching.
Clamps or a vise should be used to hold work whenever practical. Keeping your
hands free to operate a power tool is safer.
Keep tools clean for the best and safest performance. Always follow maintenance
instructions for lubricating, and when changing accessories.
Power tools should always be disconnected before servicing or when changing
accessories, such as blades, bits, cutters, and the like.
Make the workshops kid proof by using padlocks, master switches or by removing starter
keys.
A power tool will do a job better and safer operating at the rate for which it was designed.
DO NOT force a tool or an attachment, to do a job that it was not designed to do.
MAKE THE WORKSHOP KID PROOF
DO NOT FORCE THE TOOL
USE THE RIGHT TOOL
USE THE PROPER EXTENSION CORD
USE PROPER APPAREL
ALWAYS wear approved eye protection.
ALWAYS wear approved respiratory protection.
ALWAYS place the power ON/OFF switch in the OFF position when the saw is not in use.

Consult the owner’s manual for recommended accessories. Using improper accessories
may increase the risk of personal or by-stander injury.
Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally
contacted.
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.
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.
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.

WARNING
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 and cement and other masonry products
•Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:
http://www.osha.gov/SLTC/silicacrystalline/index.html

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 those dust masks that are specially designed to lter out microscopic particles.
BX-3 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
HAZARD SYMBOLS
NEVER touch electrical wires or components while the engine is running. They can be
sources of electrical shock which could cause severe injury or burns.
Keep hands, feet, hair, and clothing away from all moving parts to prevent injury.
Never operate the motor with covers, shrouds, or guards removed.
NEVER tamper with the governor components or settings to increase the maximum
speed. Severe personal injury and damage to the engine or equipment can result if
operated at speeds above maximum.

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 cur-
rent to reduce the risk of electric shock. This tool is equipped with an electric cord having an equip-
ment-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.
WARNING
• 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
WARNING
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.

Cord
Drip Loop Information
To avoid the possibility of the appliance plug or receptacle getting wet, position the machine to one
side of a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A
“drip loop,” shown in the picture below, 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 exten-
sion 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.
WARNING
Use only extension 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 disconnecting the product from the extension
cord.
WARNING
BX-3 SAFETY

10
Use of under sized 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 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.
