Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Mounting to Shop Floor Although not required, we recommend that you mount your new machine to the floor. Because this is an optional step and floor materials may vary, floor mounting hardware is not included. Generally, you can either bolt your machine to the floor or mount it on machine mounts. Both options are described below. Whichever option you choose, it is necessary to level your machine with a precision level.
Air Supply Setup The ability of this blast cabinet to accomplish its task is directly related to how well the air supply system is designed. For this blast cabinet to operate at its maximum potential with the largest blast tip, the CFM feeding the regulator should be 16 CFM at 120 PSI. Refer to your compressor Owner’s Manual and make sure that the compressor can handle the load of a blasting cabinet.
Assembly To assemble the blast cabinet: 1. With the help of an assistant, lay a sheet of cardboard on the floor to protect the media blasting cabinet, and place the cabinet on its side or back. 2. Using a #2 Phillips screwdriver, fasten all four legs to the underside of the cabinet with (16) 1 ⁄4-20 x 1⁄2" cabinet screws and flange nuts (Figure 6). Figure 7. Regulator assembly. 7. Using three Phillips screws and flange nuts, fasten the hopper valve and chute door to the hopper, as shown in Figure 8.
9. Using four cabinet screws and flange nuts, fasten the dust collector to the rear of the cabinet, so the suction port protrudes through the hole cut into the back of the cabinet (Figure 10). 13. Place the spring on the plunger shaft, and thread the jam nut and knob onto the plunger, as shown in Figure 11. Knob Jam Nut Spring and Plunger Figure 11. Canister plunger. In-line Plug 14. Re-install the dust collector into the canister. 15. Using a 10mm wrench, tighten the jam nut against the knob. 16.
18. Verify that a plastic dust sheet is affixed to the inside of the cabinet viewing window and the lamp window (Figure 13). 20. Lift the work table up, and route the blasting gun and hoses to the right-front side of the work table (Figure 15). Dust Sheets Figure 13. Viewing window and lamp window. Figure 15. Work table and blast gun positioning. 19.
22. Pour the desired amount of media into the cabinet through one of the side doors. DO NOT overfill. Test Run 23. Wait 24 hours for the silicone sealant to fully setup and dry. Otherwise, when the machine is turned on and media blasting begins, the seal may be broken, causing leakage. Once the assembly is complete, test run your machine to make sure it runs properly and is ready for regular operation.
4. Connect the machine to the power source. 5. Verify that the machine operates correctly by pushing the ON button. —When operating correctly, the dust collector runs smoothly with little or no vibration or rubbing noises and both fluorescent lamps will illuminate. —Investigate and correct strange or unusual noises or vibrations before operating the machine further. Always disconnect the machine from power when investigating or correcting potential problems. 6. Press the OFF button. 7.
SECTION 4: OPERATIONS Media blasting presents a real hazard of silicosis and other lung contamination injuries! These injuries are permanent and can get worse over time. If you use media blasting equipment without the proper eye protection and respirator, your lungs and eyes may become irreversibly contaminated. DO NOT use this blast cabinet unless you know how to use it, protect yourself correctly, and keep all unprotected bystanders away.
Basic Operation 5. This section details the correct order of operations for using the Model G0708. Install the correct tip into the blast gun, in the order shown (Figure 19). For lower air use the 6mm tip is used most often. Refer to Page 25 for air pressure and media options. To use the blast cabinet: 1. Conduct the daily check listed in Maintenance on Page 29. 2. Prepare the workpiece as discussed in PreUse Overview on Page 20. 3. PUT ON safety goggles and a respirator. 4.
7. Empty the applicable water separators and connect the media blasting cabinet to power and to the air supply. 8. Turn the regulator knob to adjust the air pressure to the desired setting (Figure 21). Typically this is a trial-and-error process, but a good range to start at is between 60 and 80 PSI. 10. Inspect the windows (Figure 23) for clarity and for any evidence of damage to the protective film. Peel off worn or damaged film and affix new sheets as required.
13. Slowly press on the foot pedal (Figure 25) and move the blast tip in a slow circular motion. Abrasive media will begin spraying from the blast gun tip. Note: If the gun or metering valve begins to clog or becomes completely clogged during use, cover the hole in the blast tip tightly, and pull the gun trigger. Air pressure will be then diverted back through the media suction piping and usually blow out the clog.
Blasting Media Media Cost vs. Productivity Often it is assumed that by using low-cost media, such as basic builder's sand or play sand, the worker can enjoy increased productivity costs because sand is so cheap. However, since sand is a "Dull Media," the blasting tip size must be increased and higher air pressure and more CFM are required to increase the blast velocity to overcome the dull media problem. This compensation usually results in longer compressor duty cycles that can overheat some units.
Steel Type Media This aggressive media creates a rough finish that accepts paint well. The media is very durable and has a long life; however, it MUST be kept very dry to prevent rusting. The main types are as follows: —Steel Grit (8-9): Compared to aluminum oxide, steel grit is softer and has a low habit of fracture, which leaves an excellent etched surface on rubber coatings, paints, and other coatings. This is a popular choice for aircraft applications. Steel grit comes in many grit sizes and hardness.
Plastic Beads Plastic abrasives are available in a variety of types such as urea, melamine, and acrylic compositions. These beads are shaped just as indicated and give reliable and consistent stripping results. Paints, varnishes, rusts, and oxidation can be stripped from soft metals, plastics, and wood. The aerospace and automotive industry are chief consumers of this blast media. —Urea (3-4): Considered to be an enviornmentally-friendly choice, urea is the most commonly used plastic media.

SECTION 7: SERVICE Review the troubleshooting and procedures in this section to fix or adjust your machine if a problem develops. If you need replacement parts or you are unsure of your repair skills, then feel free to call our Technical Support at (570) 546-9663. Troubleshooting Operation Intermittent, clogging, or no media spray at the blast gun; or striping is occurring on the workpiece. 1. Suction tube has been clogged from a contaminant. 2. Incorrect media. 3. Worn or incorrect blast tip. 4.
Motor and Electrical Symptom Possible Cause Possible Solution Dust collector won't start or circuit breaker trips. 1. Damaged or loose power cord. 4. Wiring at fault. 5. Motor brushes at fault. 6. Motor at fault. 1. Re-secure and test the power cord. Replace as required. 2. Test and replace open switch. 3. Verify that a short does not exist and that the motor brushes are not shorted, replace motor brushes if required, and reset circuit breaker. 4. Repair for open or shorted wiring connections. 5.
Motor Brush Replacement 4. Fan Cover During the life of your media blasting cabinet, you may find it necessary to replace the dust collector motor brushes. If the motor operates loudly, or the dust collector still has low suction after a new filter has been installed, the motor brushes likely have reached the end of their usable life and need to be replaced. Tools Needed Qty Phillips Screwdriver #2 ...................................... 1 Standard Screwdriver #2 . .................................
6. Lift each brush housing out of its seat and unplug the power wire (Figure 35). Power Wire —If the brushes have worn deep grooves in the commutator, we recommend replacing the motor. Typically the labor involved with re-turning the commutator on a lathe and then undercutting the insulator segments far exceeds the price of a new motor. —If the commutator only has minor wear and black-colored carbon tracking (Figure 37), use a fine crocus cloth to polish the commutator where the brushes ride.
11. Place the brush housing into the brush seat on the motor, and place the retainer over the brush housing so the lock lug drops into the slot in the brush housing (Figure 39). 14. Place the fan cover back onto the motor so the lock tangs lock onto the brush housings, as shown in Figure 41. Lock Tangs Figure 39. Brush retainer installation. 12. Install and tighten the brush housing retaining screws. 13.
