HAZARD IDENTIFICATIONS
Failure to comply with ANY WARNING listed below could result in death or serious injury.
OSHA sets exposure limits to protect workers from exposure to respirable crystalline silica, 29 CFR 1910.1053.
Airborne dust could increase the exposure levels beyond permissible limits. Breathing dust containing silica
could cause silicosis, a fatal lung disease. Breathing dust during abrasive blasting operations, post-blast cleaning
operations, and/or servicing equipment within the abrasive blasting area may expose an individual to conditions
that could cause asbestosis, lead poisoning and/or other serious or fatal diseases. Harmful dust containing toxic
material from abrasives or surfaces being abrasive blasted can remain suspended in the air for long periods of
time after abrasive blasting has ceased. A NIOSH-approved, well-maintained, respirator designed for the specific
operation being performed must be used by anyone abrasive blasting, handling or using the abrasive, and
anyone in the area of the dust.
Contact NIOSH and OSHA offices to determine the proper respirator for your specific application. The air supplied
to the respirator must be at least Grade D quality as described in Compressed Gas Association Commodity
Specification G-7.1 and as specified by OSHA Regulation 1910.134. Ensure air filter and respirator system hoses
are not connected to non-air sources or in-plant lines that may contain nitrogen, oxygen, acetylene or other
non-breathable gases. Before removing respirator, use an air monitoring instrument to determine if the
atmosphere is safe to breathe.
You must comply with all OSHA, local, City, State, Province, Country and jurisdiction regulations, ordinances and
standards, related to your particular work area and environment. Keep unprotected individuals out of the work
area.
Abrasive blasting operators must receive thorough training on the use of abrasive resistant attire which includes:
supplied-air respirator, abrasive blasting suit, safety shoes, gloves, ear protection and eye protection. Protect the
operator and bystanders by complying with NIOSH and OSHA Safety Standards.
Inspect all equipment for wear or damage before and after each use. Failure to use Original Equipment
Manufacturer repair parts and failure to immediately replace worn or damaged components could void warranties
and cause malfunctions.
OSHA requires abrasive blasting nozzles be equipped with an operating valve, which shall be designed to be
held open only by continuous hand pressure and shall close immediately upon release of hand pressure (i.e., a
“deadman” control). The valve shall not be modified in any manner that would allow it to remain open without the
application of continuous hand pressure by the operator. Failure to comply with the above warning could result in
release of high speed abrasive and compressed air resulting in death or serious injury. OSHA 29CFR 1910.244(b)
Point the abrasive blasting nozzle only at the surface being abrasive blasted. Never point the abrasive blasting
nozzle or abrasive stream at yourself or others.
Unless otherwise specified, maximum working pressure of abrasive blasting pots and related components must
not exceed 150 psi. Exceeding maximum working pressure of 150 psi could cause the abrasive blasting pot and
components to burst. Failure to comply with the above warning could result in death or serious injury.
Never weld, grind or drill on the abrasive blasting pot (or any pressure vessel). Doing so will void ASME
certification and manufacturer’s warranty. Welding, grinding or drilling on the abrasive blasting pot (or any pressure
vessel) could weaken the vessel causing it to burst. Failure to comply with the above warning could result in death
or serious injury. (ASME Pressure Vessel Code, Section VIII, Division 1)
This equipment is not intended for use in any area that might be considered a hazardous location, as described
in the National Electric Code NFPA 70, Article 500. Use of this equipment in a hazardous location could cause an
explosion or electrocution.
Never attempt to move an abrasive blasting pot containing abrasive. Never attempt to manually move abrasive
blasting pots greater than 6.5 cubic foot capacity. Always use at least two capable people to manually move an
abrasive blasting pot on flat, smooth surfaces. A mechanical lifting device must be used if an abrasive blasting pot
is moved in any other manner.

Blastmaster® Coneblast Internal Pipe Blasting Tool
HAZARD IDENTIFICATIONS
Failure to comply with ANY WARNING listed below could result in death or serious injury.
This product is not for use in wet environments. Always use a Ground Fault Interrupter Circuit (GFIC) for
all electrical power source connections. Use of this product in wet environments could create a shock or
electrocution hazard.
Frozen moisture could cause restrictions and obstructions in pneumatic control lines. Any restriction or
obstruction in the pneumatic control lines could prevent the proper activation and deactivation of the remote
control system, resulting in the release of high speed abrasive and compressed air. In conditions where moisture
may freeze in the control lines an antifreeze injection system approved for this application can be installed.
Do not cut, obstruct, restrict or pinch pneumatic control lines. Doing so could prevent the proper activation and
deactivation of the remote control system, resulting in the release of high speed abrasive and compressed air.
Use of Marco remote control switches with other manufacturer’s remote control systems could cause unintended
activation of remote control systems resulting in the release of high speed abrasive and compressed air. Only
Marco remote control switches should be used with Marco remote control systems.
Always be certain to have secure footing when abrasive blasting. There is a recoil hazard when abrasive blasting
starts that may cause user to fall and misdirect the abrasive stream at operator or bystander.
Never use an abrasive blasting pot or attachments as a climbing device. The person could slip and fall. The
abrasive blasting pot could become unstable and tip over.
For equipment manufactured by entities other than Marco, you must consult the Original Equipment Manufacturer
operator’s manuals, information, training, instructions and warnings, for the proper and intended use of all
equipment.
Flammable fumes, such as solvent and paint fumes in the work area can present an ignition or explosion hazard
if allowed to collect in adequate concentrations. To reduce conditions that could result in a fire or an explosion,
provide adequate ventilation, eliminate all ignition or spark sources, keep the work area free of debris, store
solvents and solvent contaminated rags in approved containers, follow proper grounding procedures, do not
plug/unplug power cord or turn on/off power switches when flammable fumes are present, keep a working fire
extinguisher or provide another fire suppression system in the work area. Cease all operations and correct
condition if a spark or ignition source is identified during operation.
Always depressurize the entire system, disconnect all power sources and lockout/tagout all components before
any maintenance or troubleshooting is attempted. Failure to comply with the above warning could cause electrical
shock and inadvertent activation of equipment resulting in death or serious injury.
Moving parts can present an area where crushing, pinching, entanglement or amputation may occur. Do not
place body parts or foreign objects in any area where there are moving parts.
Surfaces of heated supply tanks, drums and/or lines as well as the adjoining plumbing may become hot during
normal use. Do not touch these heated surfaces without proper protection. Deactivate and allow sufficient time for
all surfaces to cool before attempting any maintenance.
High-pressure fluid from gun, hose leaks, or ruptured components can pierce skin and can cause a serious injury
that may result in amputation. Do not point gun or spray tip at anyone or at any part of the body. Keep clear
of any leaks or ruptures. Depressurize the entire system before attempting cleaning, inspecting, or servicing
equipment.
Exposure to toxic fluids or fumes may occur during the normal operation of this system. Before attempting to
fill, use, or service this system, read SDS’s to know the specific hazards of the fluids you are using. Always use
proper Personal Protective Equipment when attempting to fill, use, or service this system.
The use of this product for any purpose other than originally intended or altered from its original design is
prohibited.
Never hang objects from the abrasive blasting pot handle. Doing so may cause the abrasive blasting pot to
become unstable and tip over.

HAZARD IDENTIFICATIONS
Failure to comply with ANY CAUTION listed below may result in minor or moderate injury.
Static electricity can be generated by abrasive moving through the abrasive blasting hose causing a shock
hazard. Prior to use, ground the abrasive blasting pot and abrasive blasting nozzle to dissipate static electricity.
High decibel noise levels are generated during the abrasive blasting process which may cause loss of hearing.
Ensure appropriate Personal Protective Equipment and hearing protection is in use.
Failure to comply with ANY NOTICE listed below could pose a hazard to personnel or property.
See Air & Abrasive Consumption Chart for estimated abrasive consumption rates and required air flow (cubic feet
per minute). Your system must meet these minimum requirements to ensure proper function and performance.
Always use abrasive that is dry and properly screened. This will reduce the potential for obstructions to enter the
remote control system, abrasive metering valve and abrasive blasting nozzle.
Moisture build-up occurs when air is compressed. Any moisture within the abrasive blasting system will cause
abrasive to clump, clogging metering valves, hoses and nozzles. Install an appropriately sized moisture separator
at the inlet of the abrasive blasting system. Leave the moisture separator petcock slightly open to allow for
constant release of water. If insufficient volume of air exists and petcock is unable to be left open (at all times)
petcock should be opened frequently to release water.
To reduce abrasive intrusion in the air supply hose, depressurize the abrasive blasting pot before shutting off air
supply from compressor.
Inspect abrasive blasting nozzle before placing into service. Damage to abrasive blasting nozzle liner or
jacket may occur during shipping. If you receive a damaged abrasive blasting nozzle, contact your distributor
immediately for replacement. Abrasive blasting nozzles placed into service may not be returned. Abrasive blasting
nozzle liners are made of fragile materials and can be damaged by rough handling and striking against hard
surfaces. Never use a damaged abrasive blasting nozzle.
Abrasive blasting at optimal pressure for the abrasive used is critical to productivity. Example: For an abrasive
with an optimal abrasive blasting pressure of 100 psi at the abrasive blasting nozzle, one pound per square inch
of pressure loss will reduce abrasive blasting efficiency by 1.5%. A 10 psi reduction in air pressure will cause a
15% loss of efficiency. Use a Needle Pressure Gauge to identify pressure drops in your system. Consult with your
abrasive supplier for the requirements of your abrasive.
Replace abrasive blasting nozzle if liner or jacket is cracked or damaged. Replace abrasive blasting nozzle if
original orifice size has worn 1/16” or more. Determine abrasive blasting nozzle wear by inserting a drill bit 1/16”
larger than original size of abrasive blasting nozzle orifice. If the drill bit passes through abrasive blasting nozzle,
replacement is needed.

AIR AND ABRASIVE CONSUMPTION CHART
Failure to comply with ANY NOTICE listed below could pose a hazard to personnel or property.
See Air & Abrasive Consumption Chart for estimated abrasive consumption rates and required air flow
(cubic feet per minute). Your system must meet these minimum requirements to ensure proper function and
performance.
When it comes to air & abrasive mixtures, more is not necessarily better. Optimum abrasive blasting efficiency
takes place when a lean air & abrasive mixture is used. To correctly set the abrasive metering valve, begin
with the valve fully closed and slowly increase the amount of abrasive entering the airstream. As you increase
the abrasive flow, watch for a “blue flame” at the exit of the abrasive blasting nozzle. Faster cutting, reduced
abrasive consumption and lower clean up costs, are benefits of the “blue flame”.
Abrasive blasting at optimal pressure for the abrasive used is critical to productivity. Example: For an abrasive
with an optimal abrasive blasting pressure of 100 psi at the abrasive blasting nozzle, one pound per square inch
of pressure loss will reduce abrasive blasting efficiency by 1.5%. A 10 psi reduction in air pressure will cause a
15% loss of efficiency. Use a Needle Pressure Gauge to identify pressure drops in your system. Consult with
your abrasive supplier for the requirements of your abrasive.
“Blue Flame”
Inspect abrasive
blasting nozzle before
placing into service.
Damage to abrasive
blasting nozzle liner
or jacket may occur
during shipping. If you
receive a damaged
abrasive blasting nozzle,
contact your distributor
immediately for
replacement. Abrasive
blasting nozzles placed
into service may not
be returned. Abrasive
blasting nozzle liners
are made of fragile
materials and can be
damaged by rough
handling and striking
against hard surfaces.
Never use a damaged
abrasive blasting nozzle.
Replace abrasive
blasting nozzle if liner
or jacket is cracked
or damaged. Replace
abrasive blasting nozzle
if original orifice size
has worn 1/16” or more.
Determine abrasive
blasting nozzle wear by
inserting a drill bit 1/16”
larger than original size
of abrasive blasting
nozzle orifice. If the
drill bit passes through
abrasive blasting nozzle,
replacement is needed.

• Improper installation and/or maintenance of components.
• Improper air supply pressure.
Initial Setup
• Blastmaster® Coneblast Internal Pipe Blasting Tool requires a customer supplied
connecting tube. The connecting tube is a length of 1-1/4” pipe that is positioned between
the blast hose and the Blastmaster® Coneblast Internal Pipe Blasting Tool. It is always
recommended that connecting tube length is same length as pipes that are being abrasive
blast cleaned. Threads at both ends of longer pipe tube must be 1-1/4-11.5 NPT. It is
recommended that the first 3 ft. of the connecting tube be a heavy wall pipe. Heavy wall
pipe will compress the Nozzle Washer (2) adequately and provides for increased wear
protection of the tools internal components. For subsequent lengths of pipe to cater for
the pipe being blast cleaned, the use of standard scheduled pipe is acceptable.
• Blastmaster® Coneblast Internal Pipe Blasting Tool comes with the full collar and button
carriage system. The collar and button carriage system comes complete with front and
rear Collars (3) and four sets of Buttons (4) (six buttons per set). Refer to application table
for button selection for various pipe ID applications. To affix collars to tool, select collar
with the larger internal diameter and mount in position over groove in Tool Holder (1). The
remaining collar, mount in position over grove in Protection Sleeve (5). Both collars can
then be secured in position by socket head screws (6).

Operating Instructions are limited to instructions found in Original Equipment Manufacturer’s
Operator’s Manuals. Please refer to all literature included with your Blastmaster® Coneblast
Internal Pipe Blasting Tool at time of delivery. If this literature is unavailable, please contact
Marco for a replacement before use.
Before use:
• Inspect components for damage. Replace any damaged components before use.
• Ensure all connections are tight and secure before use.
After use:
• When abrasive blasting is concluded, inspect components for wear or damage. Replace
as necessary.
Note:Soft abrasive media types will provide poor results due to the high break-up factor
after impacting against the deflection tip.
Note:The use of hard abrasives such as silicon carbide/aluminum oxide will produce
accelerated wear of the Deflection Tip. If hard abrasive type must be utilized, it is
recommended to inspect the deflection tip more often for accelerated wear.
1) Connect blast hose to tool assembly.
2) Place complete tool assembly inside entrance of pipe; avoid any impact on deflection tip
against pipe wall.
3) Pressurize blast pot and begin a test blast to ensure abrasive to air mixture is set to
maximum performance via abrasive metering valve.
Note:A rich mixture of abrasives to air ratio will result in premature wear to tool
components.
4) While tool is at pipe entrance, determine that you have optimum abrasive flow setting
and perform a small test blast to observe how fast tool assembly should travel within
pipe for desired cleaning result.
5) To commence production, push complete tool assembly to end of pipe that is to be
blast cleaned. Start blast cleaning process and slowly retract tool towards pipe entrance
point. Do not start blasting process from pipe entrance as this will create a build-up of
abrasive media which can create tool and collars to jam within pipe.
6) Pipes that require an extensive blast cleaning process may need multiple passes.
If after examination of the pipe it is determined a second blast is required it is
recommended that any excessive spent abrasives be cleaned and removed from the
pipe ID.
Note:If it is necessary to remove the tool from the entrance of the pipe being blasted,
ensure the blasting process has stopped and that the pressure blast pot has been
depressurized.
