Water supply: - Hook-up instructions. - Aluminum oxide microblaster use. - Bonding techniques. - Extraoral use. - Maintenance instructions. Abrasives: - The jar on the Aluminum oxide microblaster should be filled three-quarters full with clean, dry abrasive. - Abrasive should flow freely as the jar is rotated. - Moist abrasive will cling to its elf. - Abrasives are very hygroscopic and should be kept in tightly sealed containers. General abrasive uses are : - Aluminum Oxide, 90 micron, tan: Rapid removal of cements from metals. - Preparation of metals for bonding. - Aluminum Oxide, 50 micron, white: General bonding preparation of metallic and nonmetallic surfaces (Will not discolor porcelain or composites). - Microprophy B, white: stain removal. - Pit and fissure preparation.
