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.

BD7CW 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.

BD7CW 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.

BD7CW SAFETY

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 filter out microscopic particles. Where use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec-

WARNING

Sawing, grinding 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

ON

)

)

In order to prevent 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 electrical current to reduce the risk of electric shock. This tool is equipped with an electric cord which has 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.

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 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.

DO NOT abuse the cord. Never use the cord to carry the equipment or to pull the plug from the outlet. Keep the cord away from heat, sharp edges, and moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

WARNING

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 protections and may be used for this measure of safety. When using an extension cord, GFCI should be installed closest to the power source, followed by the extension cord and lastly, the machine.

WARNING

The water pump requires a GFCI. To reduce risk of electrical shock when operating the machine with the pump plugged into the 3-pole receptacle on the motor, connect the machine to a GFCI outlet. See the pump manual and informational tags enclosed separately for all pump information.

SAFETY

( (

WARNING

To avoid the possibility of the appliance or plug receptacle getting wet, position the machine to one side of a wall mounted receptacle. This will prevent water from dripping into 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. Use the drip loop as a way to prevent GFCI and plug from getting wet.

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

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.

ALWAYS make certain that the power source required for the electric motor is correct and always use the correct NEMA configuration plug. Motors can burn out when the line voltage falls 10% below the voltage rating of the motor. Failure to use proper voltage will cause the motor to overheat. Make certain that the correct size grounded (3-wires) extension cord is used.

BD7CW

The BD7CW will manually cut specimens up to 1-3/16" (30mm) in height and has a 14" (356 mm) x 14"

(356 mm) self-aligning tabletop.

Blade Lubricate

Approximately 1/3 gallon (1.3 liters) of lubricant is required to adequately cover the bottom of a 7-inch

(178 mm) blade. See Figure 5 for proper lubricant level.

The use of petroleum or vegetable based mineral is highly recommended as a lubricant for use with

BD7CW. However, water soluble cutting fluid additives can be used with water at a 30 to 1 ratio.

NOTICE: Water is not recommended for use with the Saw. The steel arbor shaft can rust. In addition, poor sawing performance and short blade life can result if water is used.

UNPACKING

The BD7CW Trim Saw has been carefully packaged for protection during transit from the factory to your location. The blade has been factory installed and the arbor nut securely tightened. No assembly is required.

If any components are missing or damaged, save the packing list and materials and advise Barranca

Diamond and the carrier of any discrepancies.

11

BD7CW 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 refined 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 Pacific 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 Pacific 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 fluids 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 flammable with a low flash point. At least 3 of our commercial cutting customers in Arizona and Pacific Northwest have burned down their shops using these fluids. Can be very tough to degrease the residue and aroma out of the cut slabs. These fluids are cheap, but very hazardous to use. Diesel is a benzene compound which is carcinogenic. All these fluids can cause severe skin rashes and other ailments.

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.

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.

16

BD7CW 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 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.

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.
