What precautions should you take when using a bead blaster?

1. Do not accidentally blast the window in the blaster cabinet. This "frosts" the glass, requiring it to be replaced.
2. Do not blast parts unless the reclaim motor is on. This will allow dust to escape into the shop through the vents in the cabinet.
3. Some bead blasters have separate reclaim cabinets. When glass beads become too small to be useful any longer, they are separated out by the reclaimer, which consists of several long, cloth tubes. Service to the reclaim unit includes moving a handle on the side of the cabinet in and out to shake spent beads from the surfaces of the cloth tubes. The bead dust falls into a tray beneath the tubes, which fills with worn-out beads and must be periodically emptied.
4. Two rubber gloves extend into the cabinet for holding the blaster nozzle and maneuvering parts. Try not to hold parts with the gloves. Holes wear into the fingers of the gloves. A small spring clamp is effective for holding small parts. Do not use the bead blaster if there are holes in the gloves.
