SAFETY PRECAUTIONS

Read and follow all safety, operating and maintenance instructions. Failure to read and follow
these instructions could result in injury or death to you or others. Failure to read and follow these
instructions could also result in damage and/or reduced equipment life. In order to prevent injury, the
following safety precautions should be followed at all times!

READ OWNER'S MANUAL BEFORE USE

Before using this equipment, ensure that the person operating this machine has read and
understands all of the instructions in the manual. Precaution is the best insurance against accidents.
Read and understand all safety precautions, messages, warnings and hazard symbols. You are
responsible for your own safety.

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.

USE 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.
Hand protection (plastic gloves) and a shop bib are recommended during sawing to prevent stains to
clothing. Avoid prolonged exposure of skin to the sawing lubricant and wash skin immediately after
contact. Do not touch the work material until the motor is off and the machine has come to a complete
stop.

ALWAYS USE HEARING PROTECTION

To reduce the possibility of hearing loss, always use hearing protection when operating power
equipment.

KEEP GUARDS IN PLACE

In order to prevent injury, never operate the saw without the guards in place!

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.

ELECTRICAL SHOCK

Never touch electrical wires or motor components while the motor is running. Exposed, frayed or worn
electrical wiring and plugs can be sources of electrical shock that could cause severe injury or burns.

DISCONNECT TOOLS

Power tools should always be disconnected before servicing or when changing accessories, such as
blades, bits, cutters and the like.

BD7 SAFETY

REDUCE THE RISK OF UNINTENTIONAL STARTS

Make sure the ON/OFF switch is in the OFF position before plugging in a power tool.

ROTATING OR MOVING PARTS

Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate the
motor with covers, shrouds or guards removed.

MAINTAIN TOOLS WITH CARE

Keep tools clean for the best and safest performance. Always follow maintenance instructions for
lubricating and when changing accessories.

KEEP WORK AREA CLEAN

Cluttered work areas and benches invite accidents.

DO NOT USE IN DANGEROUS OR HAZARDOUS ENVIRONMENTS

Do not operate equipment in dangerous or hazardous environments. Do not use power tools in damp
or wet locations nor expose them to rain. Always keep the work area well lighted. Always work in a
well ventilated area.

KEEP CHILDREN AWAY

All visitors and children should be kept a safe distance from the work area. Keep power cords
disconnected when tool is not in use.

MAKE THE WORKSHOP KID-PROOF

Make the workshops kid-proof by using padlocks, master switches and by disconnecting all power
cords.

USE THE RIGHT TOOL
Do not force a tool or an attachment to do a job that it was not designed to do.

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 FORCE THE TOOL

A power tool will do a better job and operate more safely at the feed rate for which it was designed.

USE THE RIGHT TOOL TO SERVICE THE SAW

Do not force a tool or an attachment when servicing or operating this power tool. Use the correct tools
for service or adjustments.

DO NOT OVERREACH

Keep proper footing and balance at all times by not overreaching.

DO NOT OPERATE A TOOL WHEN TIRED

When tired, take a break and relax.

BD7 SAFETY

DIRECTION OF FEED

All blades, grinding wheels or polishing belts should always be installed such that rotation is in the
direction of the arrow imprinted on the blade, wheel or belt.

ONLY OPERATE AT THE PROPER SPEED

Severe personal injury and damage to the motor or equipment can result if operated at speeds above
maximum.

NEVER LEAVE A TOOL RUNNING UNATTENDED – TURN POWER OFF

Do not leave a tool until it comes to a complete stop. Always turn the tool off, and disconnect the
power cord to its source, when leaving the work area or when work is finished. Do not leave extension
cords attached to the power cord or power receptacle (wall outlet) when leaving the work area.

CHECK FOR DAMAGED OR WORN 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 if 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.

USE RECOMMENDED ACCESSORIES AND PARTS

Consult the owner’s manual for recommended accessories and parts. Using improper parts and
accessories may increase the risk of personal and/or bystander injury.

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. The table on page 8,
shows the correct AWG (American Wire Gauge) size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the
cord.

USE THE PROPER POWER SOURCE

This tool is only to be used with a 120 volt 60 HZ power source. Ensure power source is at least 15
amps and 110 to 120 volts. Low voltage current can adversely effect electric motor performance and
overall life.

USE THE RECOMMENDED COOLING AND LUBRICATING FLUIDS

Never operate a tool dry that requires coolant or lubricant. This can lead to shortened tool life, tool
damage and personal injury.

MAINTAIN TOOLS

Keep the diamond blade sharp, the sawing lubricant clean and reservoir filled to the correct level
for the best and safest performance. Always follow the maintenance instructions for sharpening the
blade, lubricating and servicing the saw.

SILICA DUST WARNING

Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition
may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz,
brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of
airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In ad­dition, California and some other authorities have listed respirable crystalline silica as a substance
known to cause cancer. When cutting such materials, always follow respiratory precautions.

Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks
or surgical masks without a NIOSH approval number are not recommended because they do little to
protect the worker. For more information about respirator programs, including what respirators have
received NIOSH approval as safe and effective, please visit the NIOSH website at:

http://www.cdc.gov/niosh/topics/respirators

Observe OSHA regulations for respirator use (29 C.F.R.§1910.134 and §1503.1).
Visit http://www.osha.gov for more information.

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, cement and other masonry products

• Arsenic and chromium, from chemically treated lumber

For further information, consult the following sources:

http://www.osha.gov/dsg/topics/silicacrystalline/index.html
http://www.cdc.gov/niosh/docs/96-112/
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 dust masks that are specially designed to lter out microscopic particles. Where
use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec­tion, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.

WARNING

Sawing and drilling generate 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).

BD7 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 wire that has a green outer surface, 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.

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 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

outlet can be installed by a qualified electrician. The
green-colored rigid ear, plug, 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.

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 this machine. Receptacles are available, having built-in GFCI protection, and may be used for this
measure of safety.

BD7 SAFETY

ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS (continued)

To avoid the possibility of the appliance plug or receptacle getting wet, position the saw to one side
of a wallmounted 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.

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
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 under-sized extension cords result in low voltage to the motor that can result in motor burnout
and premature failure. Barranca 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.
