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).

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.

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.
Power
Cord
Power
Tool

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
Drip Loop
Figure 2: Drip Loop
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.

BD7 OIL/COOLANT
RECOMMENDED CUTTING OILS
Never run a diamond blade dry as this can immediately damage your blade. Use one of the oils/coolants recommended
below. Coolant should be kept clean and below 100° F. Sludge should be removed periodically and replaced with fresh
coolant so that your cuts will be clean and your blades will not be damaged.
Shell Diala Ax and Amber Neutral 100
Non-hazmat replacement oil for electrical transformer cooling. Excellent lubricating properties for blades and saw parts.
Flushes sludge from rock easily, degreases easily, and sludge settles in saw tank well. In Southern California, Shell Diala
Ax can be purchased from Dion and Sons, Inc (www.dionandsons.com).
Chevron Texaco Bright-Cut
A chlorine-free cutting oil with reduced sulfur and fat content. Light in color and low in odor.
Hyvolt II
Electrical transformer cooling oil. A highly rened petroleum product, available from some non-Shell oil distributors, typically only in 55 gallon drums. Same properties and performance as Shell Amber Neutral 100.
Chevron Superla #5
Food grade mineral oil. Non-hazardous lubricating oil for bakeries, breweries and food processing machinery. Good lubricating properties, degreases and settles sludge well. Can go rancid over time (1 year or less).
AVATEC 80
Food grade mineral oil, excellent for slab sawing in all our slab saws.
Texaco ALMAG
Pure petroleum based machining cutting oil. Good for slab sawing but very strong odor. Often the cheapest priced oil
available but odor is tough to eliminate.
Roc Cut
Roc Cut from Diamond Pacic is a new synthetic water soluble cutting additive with rust inhibitors. Mix 30 to 1 (water to
Roc Cut).
Roc-Oil
Roc-Oil from Diamond Pacic is an oil coolant for heavy duty cutting. Provides excellent blade protection and will not
cause rust to your blade or saw.
Under NO circumstances should any of the following fluids be used in any of our lapidary saws:
Automotive Antifreeze Coolant
Ethylene glycol based automotive antifreeze and its vapors are considered hazardous and toxic. Propylene glycol based
antifreeze is nontoxic but has practically no lubricating properties; it functions as a coolant only and its use will lead to
rapid blade wear and dulling.
Automotive Transmission Fluid
Does not have adequate lubricating proprieties for our saws; vapors are considered hazardous and toxic.
Water
A good coolant but has no lubricating properties and causes rust and degradation of exposed iron and steel parts. Causes
rapid blade dulling and premature wear. Use of water voids the warranty on all Barranca Diamond saws.
CNC Machining Fluids
Water soluable synthetic coolants (i.e. Valenite or Cimtool) are often mixed in a 20:1 blend with water. Fluid vapors are
considered hazardous. These uids do not have adequate lubricating or rust inhibiting properties for the cast iron and
steel parts in our slab and trim saws.
Diesel, Heating Oil and Kerosene
Very ammable with a low ash point. At least 3 of our commercial cutting customers in Arizona and Pacic Northwest
have burned down their shops using these uids. Can be very tough to degrease the residue and aroma out of the cut
slabs. These uids are cheap, but very hazardous to use. Diesel is a benzene compound which is carcinogenic. All these
uids can cause severe skin rashes and other ailments.

CAUTION
Tank
Figure 16: Drain Hose Cap
1. Holding the drain hose vertically, remove the drain hose cap. (Figure 16)
2. Place drain hose in a five-gallon bucket or collection container.
3. Let the lubricant flow into the bucket for proper disposal.
4. The sludge residue will likely not flow through the hose and will remain inside the reservoir. The
sludge should be removed by removing plug and push out sludge through hole.
5. Wipe the inside of the reservoir with a disposal towel. Replace drain hose cap.
6. Refill reservoir with lubricant to cover the ¼” (6.35) of the blade (see Figure 5).
7. Dispose the used coolant and sludge properly. Conform to Federal, State and Local laws, codes
and ordinances relative to environmental protection.
8. Be sure to check the level of lubricant inside the reservoir after every 3 to 5 hours of use. The
lubricant will be absorbed onto the material, combine with rock mud (sludge) and be lost to heat
and evaporation.
9. Spray WD40 lubricant on arbor shaft threads and jam nut to help prevent rust formation.
Place the ON / OFF switch in the OFF position and unplug cord before servicing
and when changing accessories, such as blades.
Rock Vise
The Rock Vise has cross feed threads attached to a knob to laterally adjust the vise so that chip thickness is accurately controlled before each chip cut. These threads should be lubricated periodically
with wheel bearing or lithium grease to allow for ease of rotation of the cross feed crank.
Should the wooden jaws on the vise become worn or start delaminating, replacement jaws can be
made from plywood.
14
Page 15
BD7 MAINTENANCE
Motor
The motor shaft has sealed ball bearings and requires no lubrication.
The motor should be protected from spray when cutting without plastic hood in place.
The motor is protected from thermal damage (overheating) with an automatic shut-off switch. If this
should occur, shut off the main motor by placing the power switch to the OFF position and disconnecting the power source. Allow the motor to cool (2 to 3 hours) and then restart the unit by turning the
switch to ON.
WARNING
Diamond Blade
Periodically, the diamond blade will need to be resharpened, should slow or poor sawing performance
occur. Dull or “glazed over” diamonds will either not cut thus stalling the saw and shutting off the
motor, or the rock vise and rock material will ride up the blade and possibly damage the blade or “dish”
the core. Once the saw begins to labor or struggle to cut gemstones, the user is advised to use a
sharpening stick and resharpen the blade. Resharpening can be performed with a few slabs cut from
the sharpening stick. If no sharpening stick is available, the user could use an abrasive material such
as cinder block or brick to remove the glazing over the diamonds on the rim of the blade.
Eventually all blades wear out and must be replaced with a new blade. New blades should be mounted on the blade arbor so that the arrow marked on the steel core is pointing in the direction of the
blade rotation while in use.
• If the arrow can't be found, use a hand lens or magnifying glass to inspect the rim and see
the head and tail of any individual diamond.
• To correctly mount the blade, the head of the diamond must cut first into the rock with the
tail trailing behind.
• For notched rim diamond blades it does not matter which way the blade is orientated on the
arbor shaft.
If the saw motor should stop during operation, the power to the main motor must
be shut off by moving the power switch in the OFF position. The motor will restart
automatically once cooled down.
If the motor does not restart after a cool down period, contact Barranca Diamond
Service at 800.474.5594.
