ATD abrasive blasting equipment is designed for cleaning and removing rust, scale, paint and dirt. It is the ideal method for stripping, polishing and etching projects. This equipment can be used with abrasive powders and liquids. This model is equipped with the standard use ceramic nozzle. SAFETY WARNING & CAUTIONS: WARNING: Airborne dust: This is one of the most serious hazards associated with blasting operations. When evaluating this hazard, it’s important to consider the concentration of dust and the size of particles. Larger particles, considered “nuisance” dust, are normally filtered out in the nose and throat. Smaller particles (10 microns or smaller) can bypass the lung’s filtering system and penetrate deep into the respiratory system, where they may cause serious damage. Safeguards are needed when smaller particles are present in the working environment. Metal dust, in addition to the abrasive being used, contributes to the generation of airborne dust. Metals such as lead, cadmium, and manganese , can be extremely toxic when inhaled. Many existing paints have a lead base. Regulations require special handling, trained personnel, and medical monitoring when lead is present. If in doubt, check it out. Don’t guess. Silica sand: This product is a potentially serious health hazard and should NOT be used as an abrasive. If silica containing (quartz) materials are selected for any reason, workers must wear a positive pressure or pressure demand respirator with an assigned protection factor (APF) of either 1000 or 2000. Silica must be contained and disposed of properly. Even if a wet blasting method is selected, silica that is allowed to migrate by either wind or water, will eventually become an airborne contaminant. Air supply: Air-supplied respirators must be used (1) when working inside of blast cleaning rooms, (2) when using portable units in areas without enclosure, and (3) under any circumstances where the operator is not physically separated from the abrasive material by an exhausted enclosure. If airline respirators and compressors are used, make su re the intake hose is placed in an area that provides clean air. An attendant should be in the area at all times, monitoring breathing air and assuring the blaster’s safety. Additional personal protective equipment: Blasting operations create high noise levels, so hearing protection is a must–for both the operator and nearby workers! Operators should also use heavy canvas or leather gloves, aprons, or legging s when appropriate, as well as safety shoes. Handling and storing abrasives: Dust is nearly always created at any point where abrasives are transferred, whether by hand or shovel. Therefore, all points of transfer must be properly exhausted and workers who handle abrasives manually should wear particulate filter respirators.

WARNING: When using pneumatic equipment, basic safety precautions should always be followed to reduce the risk of personal injury and hazards due to over pressurization. WARNING: Some dust created by abrasive blasting, grinding, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm. Your risk from exposure varies, depending on how often you do this work. To reduce your exposure to these chemicals: work in a well-ventilated area, and with approved safety equipment, such as dust masks that are specifically designed to filter out microscopic particles. WARNING: lways wear eye protection that complies with a recognized standard (CSA or ANSI) when operating or performing maintenance on this tool. User and bystanders. READ ALL INSTRUCTIONS BEFORE USING: 1.Keep work area clean. Cluttered areas invite injuries. 2.Observe work area conditions. Do not use unit in damp, wet or poorly lit locations. Don™t expose to rain. Keep work area well lit. Do not use electrically powered air compressors in the presence of flammable gases or liquids. 3.Keep children away. Children must never be allowed in the work area. 4.Do not use inappropriate attachments in an attempt to exceed the unit capacities. 5.Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts. Non-skid footwear is recommended. Always wear the hood (included), a dust mask and heavy-duty canvas gloves. 6.Use eye and ear protection. Always wear ANSI approved chemical splash goggles when working with chemicals. Wear an ANSI approved dust mask or respirator when working around metal, wood and chemical dusts and mists. 7.Do not overreach. Keep proper footing and balance at all times.

10.Make sure the air pressure adjustment is set at fi0 psifl and the shut off valve is in the off position when not in use and before attaching the air compressor. 11.Do not operate the unit when tired or under the influence of alcohol or drugs. 12.Before using check for alignment and binding of moving parts, any broken parts or mounting fixtures and any other conditions that may affect proper operation. Do not use the unit if any switch does not turn on or off properly. 13.When servicing only use parts and accessories intended for use with this unit. 14.Drain water trapped in the air pressure adjuster periodically. 15.Do not allow pressure blaster to be pressurized while unattended or not in use. 16.Make sure all equipment is rated to the appropriate capacity. Make sure that regulator is set no higher than 125 psi. 17.Periodically check the abrasive medium delivery equipment. Valves, hoses and nozzles that carry the abrasive medium after it leaves the pressure tank are subjected to the abrasive blasting action and will wear out more quickly than other components. 18.Release the air pressure in the tank before opening. Open the shut off valve to release pressure. Make sure pressure gauge reads fi0 psifl before opening the tank. Do not attempt any repairs to the pressure blaster until the gauge readsfl0 psifl. 19.Maintain correct air pressure whenever working. Do not allow pressure to exceed 125 psi. If the safety valve does not release excess air pressure, stop all work and open the shut off valve to release pressure in the tank. WARNING: The warnings and cautions discussed in this instruction manual cannot cover all possible conditions and situations that may occu r. It must be understood by the operator that common sense and caution are factors that cannot be built into this product but must be supplied by the operator. SAFETY INSTRUCTIONS FOR PRESSURE BLASTER 1. Before opening the tank release the air pressure in the abrasive tank. To do this, turn off the air supply valve (#14) to release pressure in the line. Be sure that the tank pressure gauge (#05) reads zero then open the tank. 2. Maintain correct air pressure. Pressure should not exceed 125 psi. If it does, the safety valve (#06) is supposed to release the excess pressure. If it doesn™t release excess pressure, stop all work immediately and disconnect the air compressor to reduce the excess pressure. Do not investigate the pressure blaster™s pressure problem until the pressure gauge (#05) reads zero.

ASSEMBLY USE PTFE tape for all threaded air connections 1. Assemble the intake manifold (#08). Attach the pressure gauge (#05) to the top of the intake manifold (#08), and turn the gauge so that it can be seen across the top of the tank. Next, attach the abrasive meter valve (#18) to the bottom of the manifold (#08). Attach the connector (#07A) to the bottom of the abrasive meter valve (#18); at tach the nipple connectors (#07) to the manifold (#08). Attach the safety valve (#06) to the manifold (#08) as shown in the diagram. 2. Assemble the water trap filter (#12). Two nipple connectors (#07) are screwed into each side of the filter (#12). Attach the nipple connector (#07) to one side of air supply valve (#14); then attach the male-female connector (#15) to the other side of air supply valve (#14). When ready to operate the pressure blaster, the air hose from compressor will fasten to the male-female connector (#15). 3. Place the tank (#03) on a table with four clips up. Screw the water trap filter(#12) and its parts into the hole at the side of the intake manifold. Then screw the open end of the nipple connector (#07) with intake manifold (#08) and pressure gauge (#05) attached into the threaded hole on the side of the filler pipe on top of the t ank. Again, be sure that the manifold and gauge are vertical. 4. Assemble the abrasive outlet valve into the hole at the bottom of the tank. Attach four parts in order: 1pc Nipple Connector (#07); Abrasive Metering Valve (#18); the other nipple connector (#07) and the abrasive outlet pipe (#19). 5. Assemble the abrasive meter valve. Slide two hose clamps (#26) over each end of the abrasive hose (#25). Press one end of the hose over the nipple on the abrasive outlet pipe (#19) and the other end over the intake connector (#27). Both hose ends should be firmly seated on the nipples. Slide the hose clamps along the hose to each nipple and tighten the clamps firmly. They have to resist the force of 65 to 125 psi.

6. Fasten the handlebars (#02) to the tank by using pan screw (#11), washer (#10) and hex nut (#09). Fixing axle brackets (#20) on the tank by using screw (#16). NOTE: Keep the handle curve ends upward. 7. Locate axle (#23) and slide it through the holes at the sides of the axle brackets (#20). Place one wheel (#22) at each end of the axle and fasten them into place with cotter pin (#24) and washer (#21).8. Insert the fixed foot (#17) onto the fitting on the bottom of the tank near the edge. Use the last cotter pin (#24) to hold the foot on the tank. 9. Before operating, go back over each connection, double checking to ensure that all connections are tight and properly seated. ABRASIVE SELECTION The kind of abrasive you choose will greatly influence the amount of time needed to clean a given surface area. Abrasive materials inclu de steel grit, glass bead, aluminum oxide, etc.. If you choose to reuse abrasive, remember it does wear out. The sharp edges become rounder and are less effective. It™s at that point you should replace the batch of abrasive that you are using. LOADING ABRASIVES 1. Check abrasive to be sure it™s dry and won™t clog the meter valve (#18), abrasive outlet pipe (#19), abrasive hose (#25) or other components. 2. Put on protective clothing. 3. Turn the air supply valve (#14) to the off (horizontal) position. 4. Watch the pressure gauge (#05) and make sure it reads zero. 5. Be sure to get enough abrasive into the tank to do the job at hand. But if this is a big job, only fill the tank 3/4 full and reload as needed to finish the work. Tips: If the humidity is 90-100%, the water trap (#12) won™t be able to trap all of the moisture in a 3/4 filled tank. You™d be better to reduce the amount of abrasive, load more frequently and empty the water trap more often. This will reduce the possi bility of clogging the bottom of the tank or the line.6. With the correct amount of abrasive in the tank, close the gasket (#01), then open the air supply valve (#14). 7. Check for air leaks at the filer cap as you begin to pressurize the tank from the compressor.
