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 reads 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 use to prevent stains
to clothing. 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.

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.
Use a GFCI (Ground Fault Circuit Interrupter) attached to the main motor power cord plug and keep
plugged into the power receptacle outlet source.

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 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
engine with covers, shrouds or guards removed.

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.

REMOVE ADJUSTING KEYS AND WRENCHES

Form a habit of checking to see that keys, tools, rock material and adjusting wrenches are removed
from the Cab Combo Workshop before plugging in the power cord and operating the unit.

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 OVERREACH

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

MAINTAIN TOOLS WITH CARE

Keep the diamond tools in good condition by replacing coolant water and cleaning the reservoir
frequently for the best and safest performance. Always follow the maintenance instructions for
servicing the unit.

GP6-6 WHEEL CAB MAKER SAFETY

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 from its source. 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. 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. 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. TABLE 1, 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 A GROUND FAULT CIRCUIT INTERRUPTER

Use of a Ground Fault Circuit Interrupter (GFCI) between the end of power cord and wall outlet is
required at all times.

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.

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

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.
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 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.

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 power tool.
Receptacles are available, having built-in GFCI protection, and

Metal Screw

may be used for this measure of safety.

GP6-6 WHEEL CAB MAKER SAFETY

ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS

To avoid the possibility of the appliance plug or receptacle getting wet, position the tool to one side of
a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A “drip
loop," shown in illustration below, should be arranged by the user to properly position the power cord
relative to the power source.

The “drip loop" is the 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

Drip Loop

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.

To reduce the risk of electrocution, keep all connections dry and off the ground. Don't touch the plug
with wet hands.

Use of undersized extension cords will 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 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.

GP6-6 WHEEL CAB MAKER OPERATION AND ADJUSTMENT

START-U P

Place the GP6-6 Wheel Cab Maker on a strong flat table or bench. A
power test can now be conducted to make sure the motor is operating
and all moving wheels and blades are correctly aligned and secured to
the main shaft. Plug the enclosed Ground Fault Circuit Interrupter (GFCI)
into a 110 to 120 volt 60 Hz minimum 15 amp circuit wall outlet (Fig 1).
Make sure the power switch is in the OFF (Fig 2) position before plugging
into the GFCI or extension cord.

If needed, plug an extension cord into the GFCI. If an extension cord is
used, use one that is at least 14-guage wire and no longer than 25 feet.
The GP6-6 Wheel Cab Maker power cord is attached to the ON/OFF
power switch on the back side of the unit.

To energize and test the GFCI, push the RESET button (Fig 3) on the
switch and a red window will appear to indicate the switch is energized. If
the TEST button is pushed, the switch will click off indicating the GFCI is
functioning correctly. Push the reset button again to re-energize the GFCI.

GP6-6 WHEEL CAB MAKER OPERATION AND ADJUSTMENT

PUMP SET-UP

A submersible electric water pump is used to supply water to the polishing wheels as coolant and
lubricant. The pump has a flow control adjustment on one side and should be adjusted for maximum
water intake (Fig 5).

Fig 5 - Pump inlet adjustment set to
maximum flow

Fig 6 - Pump hose attached to water

Fig 7 - Pump hose attached to valve

Insert one end of the 1/4" ID water hose over the water pump outlet (Fig 6) and the other end over
the barbed end of the water valve inlet (Fig 7). It is recommended that a 5 gallon bucket be used as a
water reservoir into which the submersible pump should be placed (Fig 8). The level of the reservoir
water should be monitored so that water the pump always remains fully submerged.

Fig 8 - Place the Water Pump in an
external container

Fig 9 - Water valve in the right hand
station position

Fig 10 - Electrical outlet for water
pump

The pump should be plugged into the female receptacle plug attached to the back of the motor (Fig

10). Power to run the pump will occur once the power switch lever is placed in the ON position. The

pump should be operated in maximum flow setting. This will allow sufficient water to reach the three
needle valves that control the water flow. Do not recirculate drained dirty water from the reseviors
back into the water inlet under any circumstances.

12

GP6-6 WHEEL CAB MAKER OPERATION AND ADJUSTMENT

PUMP SET-UP (continued)

Keep the water hose away from the electric motor to prevent damage from moving parts and electric
shock hazard. The pump should always be used with clear, clean water so as to avoid grit/abrasive
material, mud or rock fragments from scratching the gemstones during polishing or clogging the pump
valves. The Water Valve (Fig 9) at the back of the motor, directs the water to either the right or left­hand station. Position the valve with the handle pointing toward the side you want to use, to direct the

water there.

NEEDLE VALVES

The stainless needle valves (Fig 11) are for fine control of water to each of the six grinding and polish­ing stations. For best results, close the valves to the stations not in use. To shut off flow to a needle
valve, simply turn the grey ribbed knob clockwise until it closes to a firm stop (do not over-tighten).
To open maximum flow to a needle valve, simply turn the grey ribbed knob counterclockwise until the
valve stops. It may take up to 30 seconds for water flow rate to change to a specific station.

Fig 11 - Stainless needle valves Fig 12 - Drain with hose installed

DRAIN FITTINGS

A length of 3/8" ID tubing is provided for drainage of excess water from the front base of the reservoir
where a drain is located at the base of the reservoir (Fig 12).

To drain off the excess build-up of cooling water from the diamond wheels, connect 3/8" ID clear tub­ing to the drain and route it into a 5 gallon collection bucket or drain for dirty water. Discard dirty water
appropriately once collection bucket fills up.

Do not recycle dirty water from the collection bucket as the contaminants (rock grit, mud, slurry and
abrasive particles) will likely scratch the gemstone material being worked and possibly clog the stain­less steel water control valves or submersible pump.

13

GP6-6 WHEEL CAB MAKER OPERATION AND ADJUSTMENT

DIAMOND WHEELS

The GP6-6 Wheel Cab Maker comes equipped with two 6" OD x 1-1/2" brazed diamond wheels in
two diamond abrasive grit sizes (80 and 170 mesh or grit). Both wheels are manufactured to a low
tolerance OD circumference run-out for maximum wheel life and to prevent pounding and poor per­formance during grinding. The high temperature brazed diamond bond provides excellent abrasive
performance when grinding the rough shape of the gemstone material. Diamond wheels must have an
uninterrupted flow of water during use for proper cooling and flushing of slurry and rock fragments.

Rough shaping of the gemstone material should be performed first with the 80-grit wheel with maxi­mum water flow. It is recommended that you only pump clean water to the GP6-6 Wheel Cab Maker
water system and never recycle your drain water back to your grinding wheels.

Due to the steel alloy core construction and brazed nickel diamond bounding of both wheels, a “ring­ing" noise will be heard during grinding and sanding. This is normal and should be of no concern.
Should coolant/flushing water flow be interrupted while grinding with the brazed diamond wheels, the
diamond may “glaze over" or dull the diamond bond.

Always ensure there is a clear, constant drip of water flowing off the rotating wheels into the reservoir
tank. Also, don’t over force the gemstone material into the diamond wheel surface while grinding. Al­low the diamond bond on the wheel to work smoothly with a constant and steady application of hand
pressure. Rotate your gemstone frequently while grinding to uniformly remove material, nicks and flat
spots while rounding and contouring.

Remember, satisfactory results are dependent on the user's skill and experience, as well as the gem­stone and equipment being used.

DIAMOND NOVA WHEELS

The GP6-6 Wheel Cab Maker comes with Nova Wheels (6“ OD x 1-1/2" wide) in abrasive grit sizes:
280, 600, 1,200, and 3,000 (6 micron).

Under no circumstances should the Nova Wheels be used dry. Dry grinding will cause them to wear
out prematurely. Therefore, keep a constant stream of water from the needle water control valve on the
top of the hood ON at all times. Always pump clear and clean water to the diamond wheels. For best
results always dry the gemstone material and check for scratches before proceeding to the next wheel
or diamond grit size. Do not skip wheels in the four wheel sequence (280, 600, 1,200, and 3,000 grit).

POLISHING WITH DIAMOND PASTE

The GP6-6 Wheel Cab Maker comes with three syringes (5 grams each) of diamond paste in abra­sive grit sizes: 8,000, 14,000 and 50,000 mesh. These diamond pastes are to be used with the three
6" Polytex polishing pads. Once the gemstone material has been sanded and polished with the 3,000
grit (6 micron) diamond wheel, remove the paper backing on one of the Polytex pads to expose the
adhesive surface, placing it firmly without creases on the foam rubber convex surface of the 6" end
polishing disc on the right end (Fig 13).

Fig 13 - Polytex pad being applied to
the convex polishing disc

Lightly smear with your fingertip a small amount of diamond paste on the center of the mounted Poly­tex pad with the polishing disc rotating. The diamond paste will evenly spread over the surface of the
Polytex pad once polishing of the gemstone starts. No water or extender fluid is needed to effectively
disperse the diamond paste from the syringe to the Polytex pads. Move the gemstone in a rocking
and rotating motion from the center of the disc toward the outside edge to achieve a uniform polished
surface.

Use only one dedicated Polytex polishing pad with each respective diamond paste syringe (i.e. keep
a labeled Polytex pad for the 8,000 grit paste in a zip-lock bag labeled 8,000 grit). Do not use a single
Polytex pad with two or more diamond pastes or else cross-contamination and poor polishing of the
gemstone material may result.

The Polytex pad can be removed from the convex polishing disc by slowly pulling the Polytex pad off
the disc. Place pad in a zip-lock plastic bag properly labeled with the syringe paste diamond grit size
for future use. If the adhesive backing becomes weak with repeated use, you can apply a few drops
of 3M On/Off cement to improve the adhesive connection to the foam rubber disc.

15

GP6-6 WHEEL CAB MAKER OPERATION AND ADJUSTMENT

POLISHING WITH THE LEATHER BUFF PAD

For final polished gemstone results, place the 6" cowhide leather pad (rough side out) on the foam
rubber polishing disc using the 3M On/Off adhesive cement. Only use a small amount (8 to 10 dabs)
of 3M On/Off adhesive cement on the smooth cowhide surface, smearing it uniformly before placing
it over the foam rubber on the polishing disc. Buff the gemstone using a rocking motion (Fig 14 & 15).
It is not necessary to use any polishing media or liquid (water) when buffing the gemstone with the
leather disc. Be sure to firmly grip the gemstone by hand or with a dop-stick (wood dowel or alumi­num rod) cemented or epoxied to the back of the gemstone while using the leather buff pad. When
the final polish finish of your gemstone has been achieved, remove the leather disc and place it in a
zip-lock bag to protect it for future use.

SET UP OF LOC-LINE SYSTEM ON GP6-6 Wheel Cab Maker

The Loc-Line magnetic manifold will need to have the 3/8" OD clear tubing from the submersible pump
inserted into the other end of the 1/2" OD clear tubing (Fig 15).

The magnetic base manifold should be positioned on the metal hood of the GP6-6 Wheel Cab Maker
unit at the far right end. This position will allow for the direction of water flow to the 6" resin diamond
pads during use (Fig 17). Water flow can be adjusted with orange adjustment lever (Fig 18).

GP6-6 WHEEL CAB MAKER MAINTENANCE

USE OF 6" RESIN DIAMOND PAD

The 6" resin 14,000 grit diamond pad is positioned on the right end of the shaft, adjust the Loc Line
nozzle tip to the center of the resin diamond pad (Fig 19). This will allow the water stream/drip to flow
over the pad while turning to cool and flush gemstone grindings during use.

Always pump clean, clear water through the Loc Line manifold and discard dirty water and grindings
from the collection container periodically. Do not recirculate water as contaminants may scratch the
gemstone material. The resin diamond pads should never be used dry or they will likely be prema­turely worn out or permanently damaged. A small amount of water directed at the center of the resin
diamond pads is required to flush the gemstone grindings and keep the pad cool. Excess water flow
directed to the pad is not necessary and will only make a mess of your work area. The 6" resin dia­mond pads can be used with both flat and domed material, the user should rock and rotate the domed
gemstone material during polishing, but for flat polishing the user needs to move the material flat face
across the pad to fully polish the face uniformly. Gemstone material should be held firmly by the user’s
finger tips while rotating and or moving the material over the face of the 5" resin diamond pads. Do
not hold the gemstone material too close to the bottom edge of the resin pad or the material may jam
the users finger against the reservoir base. In some cases, the user may polish gemstones after
grinding/sanding with the 80 and 170 mesh brazed diamond wheels and four Nova diamond wheels
and 14,000 grit end disc without the use the Polytex 6" pads with diamond paste. Final polishing buff­ing can be performed with the Polytex pads (if desired, to 50,000 grit) and leather cowhide mounted to
the polishing foam disc.

SHAFT REASSEMBLY

Reassembly of the shaft with the new diamond wheels is the reverse of the disassembly instructions.
Please keep the following points in mind when reassembling:

1. Use a good quality wheel bearing grease to coat the steel shaft with a liberal amount of grease
before mounting the wheels, flanges and spacers.

2. Be sure the diamond wheel bushings are installed.

3. Some brazed wheels have 2 flush faces, and some have 1 flush and 1 recessed face (Fig 25 &

26). A second spacer (.250 long) is needed behind the flange of any recessed face to insure proper
wheel spacing (Fig 28). See parts explodes for illustration of proper wheel, flange and spacer
setup.

4. There should be a flange installed on both sides of each diamond wheel. Make sure the concave
side of the flange faces the wheels (Fig 27 & 28).

5. Install the Nova resin diamond wheels on the shaft with arrow of rotation facing direction of rotation.
