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.

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.

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.

MAINTAIN TOOLS WITH CARE

Always follow the maintenance instructions for servicing the GP6-6 Wheel Cab Maker.

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 the 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 vacuum cleaner.

WARNING

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.
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

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.
