HEALTH RISK WARNING

WARNING!

Please do not use the Sand Blaster until you have read this manual and understand its contents and warnings. These warnings are included for the health and safety of the operator and those in the immediate vicinity.

Keep this manual for future reference. Dust created by power sanding, sawing, grinding, drilling, and other

construction activities may contain chemicals known to cause cancer, birth defects or other reproductive harm, and respiratory illnesses. Some examples of the substances include:

• Lead from lead-based paints
• Crystalline silica from bricks, cement, and other masonry products. Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies depending on how often you do this work. To reduce exposure to these chemicals, Work in a ventilated area and wear approved safety equipment, such as a dust mask specially designed to filter out microscopic particles.

• Abrasive blasting produces harmful dust. Everyone in the blasting area must wear a properly fitted and maintained NIOSH-approved supplied-air respirator.

SILICOSIS AND OTHER DUST WARNINGS

Breathing dust from silica sand may cause silicosis, a fatal lung disease. Breathing dust during blasting operations may also cause asbestosis and/or other serious or deadly diseases.

A NIOSH-approved,well-maintained air-supplied abrasive blasting respirator must be used by anyone blasting, anyone handling or using media containing toxic substances, or media with more than one percent crystalline silica, and anyone in the area of the dust.

Harmful dust can remain suspended in the air for long periods after blasting has ceased, causing serious injury or death. Before removing the respirator, use an air monitoring instrument to determine if the atmosphere is safe to breathe. Contact the local OSHA or NIOSH office to determine the proper respirator.

Supplied-air respirators do not remove or protect against carbon monoxide (CO) or any other toxic gas. A carbon monoxide removal device and a monitoring device with the respirator are used to ensure grade D-quality air. Follow all applicable OSHA standards and OSHA regulation 1910.134(d).

Sand Blaster Assembly Instructions

• Refer to the drawing for step 1, assembling the intake manifold. First, attach the pressure gauge (16) to the top of the intake manifold, turning the gauge so that it is visible across the top of the tank. Next, attach the throttling valve(19A) to the bottom of the manifold. Attach the nipple connector (21) to the throttling valve. Attach the joint pipe (14) to the manifold.
• Refer to the drawing for step 2, to assemble the water trap filter(18) nipple connector(17) is screwed into each side of the filter. On one side, attach the air supply valve(19) to the nipple connector(17), and then attach the male/female connector (20) to the other side of the air supply valve. When you’re ready to operate the abrasive blaster, the air hose from the compressor will be fastened to the male/female connector (20).
• Place the tank (01) on a table with the four clips up. Refer to the drawing for the step. Screw the water trap filter (18) and its parts into the hole at the side of the intake manifold. Then screw the open end of the joint pipe (14) with intake manifold(15)and pressure gauge (16) attached into the threaded hole on the side of the filler pipe on Top of the tank. Again, ensure that the manifold and gauge are vertical.
• Refer to the drawing for step 4, assembly of the abrasive outlet valve into the hole at the bottom of the tank. Attach four parts, in order: nipple connector(17), abrasive metering valve (19B), nipple Connector (17), and the abrasive outlet pipe(23).

Refer to the drawing for step 5, assembly of the nozzle DEADMAN valve (34). In this assembly process, you’ll select one of the four nozzles (28)—this is not a permanent selection, as you may change nozzles according to the job being done. Screw the adapter (26) into the nozzle DEADMAN valve (34). Screw the gasket (27) into the nipple connector, then add a nozzle(28)and the nozzle cap-nut (29).

• Refer to the drawing for step 6, connecting the abrasive metering valve assembly (step 4) and the assembly (step 5). Slide the two hose clamps(24) over each end of the abrasive hose (25), press one end of the hose over the nipple on the abrasive outlet pipe (23) and the other end over the adapter (26). Both ends should be firmly seated on the nipples. Slide the hose clamps along the hose to each nipple and tighten the clamps very firmly.
• Fasten the two handlebars (06) to the tank using four pan screws(08), four washers (10), and four hex nuts (09). Note: Keep the handle curved upward.
• Locate the axle (05), and slide it through the holes in the sides of the handlebars (06). Place one wheel (02) at each end of the axle and fasten them in place with cotter pins (03) and a washer (30).
• Insert the fixed foot (04) onto the fitting on the bottom of the tank near the edge. Use your last cotter pin (03) to hold the foot to the tank.
• Before beginning operations, review each connection and double-check to ensure all are tight and properly seated.

WARNING!

Disconnecting the hose while the Unit is under pressure could cause serious injury or death. Use safety lock pins and safety cables in all coupling connections to help prevent hose couplings from accidental disconnection.

If twist-on air hose couplings are used, they must be secured by safety lock pins or wires to prevent accidental disconnection while under pressure. Hose disconnection while under pressure could cause serious injury

Sand Blaster Safety Procedures

CAUTION: READ THESE SAFETY PROCEDURES IN THEIR ENTIRETY. PARTS OF THE OPERATING INSTRUCTIONS ARE WITHIN WARNINGS.

These procedures are not intended to be exhaustive due to the many variables in the abrasive blasting field. Therefore, we INSIST that the hands, ears, mouth, nose, and eyes be covered with appropriate safety protection.

1. Do not place fingers, body parts, or components in the filler plug seal area when the sand blaster is being pressurized. Failure to keep body parts from the filler plug area will result in serious injury.
2. Do not exceed the maximum working pressure of 125 PSI. Failure to keep maximum working pressure below 125 PSI can cause the blast machine to burst, causing death or serious injury.
3. Everyone in the blast area, including the equipment operator, should correctly use and maintain a NIOSH-approved air-supplied respirator, even after blasting has ceased. Harmful dust can remain suspended in the air for long periods after blasting has stopped, causing injury or death.
4. Before using the pressure blaster, wear safety glasses, gloves, and a NIOSH-approved respirator. Always wear these protective items when operating and while servicing your abrasive blaster. While a protective hood is provided to help protect you from flying parts as you use the machine, the hood does not protect against airborne particles.  Anyone must use a well-maintained air-supplied blasting respirator.
5. Use thick gloves to protect your hands.
6. Use backboards to prevent overspray from hitting someone or something else because the dust will travel a long distance. Blast in a large open area to minimize abrasive accumulation in the surrounding areas.
7. Please do not pull the media tank around by the abrasive hose or let the tank fall over a fitting, as it may break rendering the machine unsafe. Media and air under 125 PSI have a very high destructive force. Never leave a pressurized machine unattended. If an emergency occurs, such as a burst blast hose, shut down the machine immediately.
8. Drain air out of the tank through the inlet valve and disconnect power before maintenance cleaning of any kind. When removing the nozzle, caution must be exercised as air pressure may still be in the hose if the nozzle is plugged.
9. For safe operation, perform recommended preventive maintenance on the sand blaster tank, remote unit, and accessories. Replace all worn parts before they fail. Wearing components must be replaced immediately. Failure to replace worn components could expose the operator or bystanders to high-speed media and compressed air, causing serious injury.
10. Do not use corrosive materials of any type in the unit. Use only clean, dry media.
11. Do not splice abrasive hose. The splice will wear out quickly and may violently spray media over the surrounding area. A worn blast hose could suddenly fail by bursting. Couplings and nozzle holders may not adequately grip worn hose, causing them to blow off under pressure. Compressed air and abrasive escaping from a burst hose, or a disconnected coupling or nozzle holder, could cause severe injury.
12. Welding, grinding, or drilling on the blast machine could weaken the vessel. Compressed air pressure could cause a weakened blast machine to rupture, resulting in death or serious injury. Welding, grinding, or drilling on the blast machine vessel, without a National Board stamp, voids the ASME and National Board certification if applicable.
13. Always place the machine so the outlet is pointed away from objects or persons. Stand clear of the path of exiting abrasive. It may come out at high velocity. The impact of exiting an abrasive could cause severe injury.
14. Do not use electrical adaptors that eliminate the ground prong on 115-volt plugs. Failure to properly ground the machine can cause injury from electric shock and equipment damage. Always ground the blast machine to help reduce the possibility of static electricity and its related hazards.
15. Do not use this sandblaster in hazardous areas or where flammable gases or liquids are present. Failure to do so may cause an explosion, resulting in serious injury.
16. The use of this equipment can create static electricity. Do not use within fifty feet of any explosive, potentially explosive substances, or their vapors, as an explosion can occur.
17. Do not overfill the tank with media or fill it to within 6 inches of the top.
18. BEFORE OPENING THE TANK, release the air pressure on the abrasive tank. To do this, turn off the air supply valve(19) and push down to open the DEADMAN valve(1) to release pressure in the line. Ensure that the tank pressure gauge reads zero, then open the tank.
19. MAINTAIN CORRECT AIR PRESSURE: A maximum of 110 PSI is recommended; pressure must not exceed 125 PSI. If pressure exceeds 125 PSI, stop all work immediately and disconnect the air compressor to reduce the excess pressure. Do not investigate the blaster’s pressure problem until the gauge reads zero.

Sand Blaster Operating Instructions

OPERATING TECHNIQUE:

1. Connect the air hose to the air inlet valve. The manufacturer recommends using a minimum incoming air hose of 1/2″ I.D. Using an air hose smaller than 1/2″ I.D. will restrict air volume and result in poor unit operation. Before air injection, certain air inlet valves and nozzle valves are in the OFF position. With the Deadman Valve closed and filler plug tight, open the air inlet valve, allowing air to pressurise. The operating range of the unit is 40 to 110 PSI. Note: Refer to the nozzle selection chart on page 11 for proper nozzle selection. After proper nozzle selection, insert the nozzle into the retainer base. Set the washer again, slide the retainer nut over the nozzle, and tighten by hand.
2. The Pressure Blaster has a unique semi-automatic pull-up, closed design. The manufacturer recommends a fine grade abrasive with granular sizes similar to table salt. This assures proper flow and reduces the possibility of nozzle obstruction. When ready to pressurise the container, pull up the closure and turn on the incoming air. The internal air pressure will seal the closure.
3. With the blaster pressurised and abrasive flow regulator valve at the unit’s base closed, open the ball valve allowing air to flow through the bypass hose to the base of the unit. Then, holding the abrasive hose by the nozzle retainer housing with the nozzle directed away from the unit and operator, quickly squeeze the Deadman Valve fully open and adjust the regulator valve at the base of the tank to bleed the abrasive into the air flow. Slowly open the regulator valve until abrasive material is slightly visible. Once the regulator flow valve is adjusted to the desired setting, further adjustment should only be required when changing the grade of abrasive material or when a nozzle with a different ID is used. Opening the regulator valve too far will result in a clogged hose or nozzle. For best performance, the Deadman Valve should be opened and closed quickly.

WARNING!

Disconnecting the hose while the Unit is under pressure could cause serious injury or death. Use safety lock pins and safety cables in all coupling connections to help prevent hose couplings from accidental disconnection.

If twist-on air hose couplings are used, they must be secured by safety lock pins or wires to prevent accidental disconnection while under pressure. Hose disconnection while under pressure could cause serious injury

AIR ABRASIVE SUPPLY REQUIREMENTS

Abrasive blasting requires a large volume of air at high pressure. The efficiency of your abrasive blaster can be adversely affected by using a too-small air supply hose, insufficient air pressure, or an overly large nozzle.

We recommend that an air pressure in the 60-110 PSI range will provide the best Results.

LOADING ABRASIVES INTO THE TANK

1. Check your abrasive to be sure it’s dry and won’t clog the metering valve (19B), abrasive outlet pipe(23), hose(25), or other components.
2. Wear protective clothing, a full hood and an MSHA/NICOSH-approved respirator.
3. Turn the air supply valve(19) to the off (horizontal)position.
4. Push down to open the nozzle DEADMAN valve(34). 5. Watch the pressure gauge(16)and ensure it reads zero pressure.
5. Remove the filler cap(13)from the top of the tank. 6.
6. Insert the funnel (31), and pour the abrasive into the funnel. Be sure to get enough into the tank to do the job. But if this is a big job, fill thetankonly3/4 full, and reload as needed to finish the work. TIPS: if the humidity is 90/100%, the water trap (18) won’t be able to trap all of the moisture in a 3/4 tank.Better to reduce the amount of abrasive, load more frequently, and empty the water trap more often. This will reduce the possibility of clogging the bottom of the tank or the line.
7. Close the filler cap with the correct amount of abrasive in the tank (13).
8. Close the nozzle shut-off valve(198), and open the air supply valve(19).
9. Listen for air leaks at the filler cap as you begin to pressurise the tank from the compressor. Fix any leaks before operating.

AIR COMPRESSOR RECOMMENDATION

To permit efficient air compressor operation, follow these guidelines: Use a smaller size nozzle to control the air demand.

1. Do not blast continuously. Stop the blasting operation periodically to allow the compressor to cool.
2. No compressor is designed to run at full RPM constantly. Use 70% of the rated output. Use a minimum 1/2″ air hose or metal piping from your air compressor to the blaster. If your compressor is creating excessive moisture, we recommend using a water trap or a moisture separator. Open the bleeder valve until water slowly flows out continuously.
3. The air compressor should be drained at the bottom of the supply tank through a drain valve and blown down daily. Draining three or four gallons of water from the supply tank on a high-humidity day is not unusual. An additional supply tank will help.
4. Keep dust and media created by blasting away from the air compressor unit. Observe the blaster’s maximum air pressure requirements. Either set your compressor to run within these limits or use a pressure regulator valve to reduce the air pressure to the appropriate range.

ABRASIVE (MEDIA) USAGE

1. Moisture in the media will eventually damage the blaster tank or plug the system. To avoid this problem, keep the media and compressor air dry.
2. If the media is moist, screen and dry it before use.
3. Do not leave media in the tank after blasting because it can absorb moisture and impair blasting performance.
4. Store media in a dry place. Keep it off the ground or concrete floors and put it on a wooden skid.
5. If the humidity is excessively high, it may not be advisable to blast at that time.
6. Consider using different grades or media types to prevent nozzle clogging due to high moisture content.
7. Do not use sand.

Warning!

Do not fill the pressure vessel to within six (6) inches of the top of the vessel. If a hose is accidentally disconnected during use, media spray may occur. See the respiratory-related WARNINGS at the beginning of the manual.

Black Beauty

Black Beauty is used when paint and rust have to be removed from steel, such as car bodies, tanks, or heavy machinery. It is superior to silica because it only has 0.1% free silica, is faster cutting, can be reused, is moisture-free, and will not pack or absorb moisture.

Steel Grit

Steel grit is used for high-speed cutting on rusty metal and hard-to-remove paint. SteelGrit is popular because it leaves a very smooth finish. It is also comparable in price to most other speciality abrasives. Steel Grit is recommended for reclaimed systems or cabinets.

Glass Bead

Glass Beads create a satin or matte finish, and they are recommended for reclaimed systems or cabinets.

Aluminum Oxide

Aluminium Oxide is a high-quality abrasive that is sharper than sand(not recommended) and cuts twice as fast as sand. It leaves a smooth texture with no pits. Aluminium Oxide is rougher than a glass bead and can be used repeatedly. It is among the most economical abrasives in any reclaim systems or cabinets.

Plastic Grit

It is primarily used to strip aluminium and fibreglass. It is excellent for stripping paint, light oxidation, and surface rust. It is recommended for use in blast cabinets because it creates very little dust. It works quickly, lasts a long time, and increases visibility within the cabinet.

TROUBLE SHOOTINGTIPS

Sand Blaster Maintenance

WARNING!

Failure to observe the following before performing any maintenance could cause serious injury or death from the sudden release of compressed air:

• Depressurise the sand blaster machine.
• Disconnect the power supply.
• Lockout and tag out the compressed air supply.
• Bleed the air supply line to the blast gun.

Worn components must be replaced immediately. Failure to do so could expose the operator or bystanders to high-speed media and compressed air, which could cause death or serious injury. Leaks around couplings and nozzle holders indicate worn or loose-fitting parts.

Nozzle holders and couplings that do not fit tightly on hoses and nozzles that do not fit tightly in nozzle holders could disconnect while under pressure. Impact from nozzles, couplings, hoses, abrasives, and disconnected parts while under pressure could cause severe injury.

To ensure a long and efficient operational life of the Deadman Handle, it is highly recommended that the following procedures be followed:

1. Periodically(after 5-6 months of moderate use or after 10-15 hours of heavy industrial use) replace all hose adaptors for abrasive flow use only.
2. Replace the rubber sealing block after 7-10 hours of use to maintain proper shut-off.
3. Check abrasive hose when it begins tos sputter or leaks media or air around the hose or handle area.
4. Replace the nozzle when it wears to the next larger size.
5. Check the urethane gasket in the pull-up closure when the air leaks excessively from the opening (ensure the gasket is free from media).

OTHER MAINTENANCE ITEMS

1. You should try to protect your air compressor from any damage it may receive from your abrasive blasting work. Your best option is to keep the compressor upwind from the abrasive blasting; the greater the distance between them, the better. Other than that, you should continue standard maintenance procedures for the compressor.
2. Some parts of the abrasive blaster will wear much more rapidly than others. The parts needing close attention carry the air/abrasive mixture, starting with the abrasive hose (25) and going through the metal fillings, the DEADMAN valve (34) and the ceramic nozzles (28).
3. If air leaks develop in any of these parts, you should stop all work and find what needs to be repaired or replaced. When it’s new, the abrasive hose (25)has 2 cord piles and the walls are 1/4″ thick. As the interior diameter is abraded, this wall becomes thinner and thinner. One way to inspect the hose and other parts affected by the blasting is to wear protective clothing. Then, pressurise the system, close the nozzle, and shut off the valve (19). Listen for air leaks, and fix any leaks before operating.

You can also spot places in the hose where the wall is getting very thin. These show up as blisters in the hose; if you find such a blister, get a new hose immediately. If that blister breaks, the abrasive will come out of the side of the hose.
