4. ATD 8401 40 LBS PRESSURE BLASTER INSTRUCTION MANUAL 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 amp 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
5. es 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 Do not overreach Keep proper footing and balance at all times Do not reach over or across running machines Keep machine clean for better and safer performance Follow the instructions for lubricating and changing accessories Inspect compressors cord periodically and if damaged have it repaired by a qualified technician Inspect all hoses for leak prior to use The handle must be kept clean dry and free from oil and grease at all times Be sure that keys and adjusting wrenches are removed from the unit or work surface before using 10 Make sure the air pressure adjustment is set at O PSI 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
6. ety 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 Always wear eye protection that complies with a recognized standard CSA or ANSI when operating or performing maintenance on this tool User and bystanders mA CH S QD READ ALL INSTRUCTIONS BEFORE USING 1 Keep work area clean Cluttered areas invite injuries 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 Keep children away Children must never be allowed in the work area Do not use inappropriate attachments in an attempt to exceed the unit capacities 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 glov

12. worn or damaged Teflon tape at joints 4 Check for worn abrasive hose and fittings The abrasive metering valve manifold and all parts after the abrasive is ejected from the tank are subject to rapid wear due to the flow of abrasive Watch especially for leaks blistering bulging or thinness of the hose Replace any parts which appear worn ABRASIVE SELECTION The kind of abrasive you choose will greatly influence the amount of time needed to clean a given surface area Abrasive materials include silicon carbide alumina and many others Be sure that the abrasive you use is thoroughly dry Damp abrasive can cause clogging of your pressure blaster While you may reuse abrasive remember that the abrasive does wear out After using abrasive becomes smoother and rounder thus reducing abrasive effectiveness Reusing abrasive may also cause clogging due to debris contained in the mixture from prior use ABRASIVE FLOW ADJUSTMENT Choose a larger nozzle for a broader spray pattern Choose a smaller nozzle for more focused abrasive blasting Adjust air pressure with the air pressure adjuster 9 Adjust abrasive flow with abrasive metering valve 26 Watch for abrasive clogging Depressurize if necessary and replace the abrasive with drier or cleaner abrasive SAFETY AND HEALTH CONSIDERATIONS Before opening tank be sure that it is not pressurized Be sure that the gauge reads 0 PSI Depressurize the tank before opening it by
