BX-44
SAFETY
USE THE PROPER EXTENSION CORD.
If using an extension cord make sure it is in good condition rst. 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. 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, dust
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.
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.
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 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 nished.

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:
WARNING
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.gov/SLTC/silicacrystalline/index.html
http://www.oehha.org/prop65/out_of_date/6022kLstA.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.

ELECTRICAL REQUIREMENTS & GROUNDING INSTRUCTIONS
ADAPTER
In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be
followed at all times!
WARNING
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 t the outlet; have the proper outlet installed by a
qualied 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 qualied 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 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 qualied 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.

WARNING
Use only extensions cords that are intended for outdoor use. These extension cords are identied 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.
• 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.
WARNING
To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug
with wet hands.
WARNING
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 fty (50) foot extension cord would require an AWG size of 12.
