169 Specifc Saf ety Instr uctions f or P o w er T ool Gr oups In addition to the General Safety Instructions, the following are safety instructions and warnings that apply to the safe operation of specifc power tool groups. Consult ANSI B186.1 Safety Code for Portable Air T ools. Available from: America National Standards Institute (ANSI), 1 1 W . 42nd St., 13th foor , New Y ork, New Y ork 10036, (212) 642-4900; or the European Committee for Standardization, Rue de Stassart 36, 1050 Brussels, Belgium. • Never use hand sockets. Use only impact sockets in good condition. Sockets in poor condition reduce impact power and could also shatter , resulting in personal injury . • When using a universal joint, never free run the tool, it may run too fast and cause the joint to be thrown from the tool. • Always use the simplest hook-up possible. Long springy extension bars and adapters absorb impact power and could break loose resulting in personal injury . Instead, use deep sockets whenever possible. • For tools using the pin and o-ring socket retainer , use the o-ring to securely retain the socket pin. Impact w renches • Serious injury can result from over-torqued or under-torqued fasteners, which can break, or loosen and separate. • Released assemblies can become projectiles. Assemblies requiring a specifc torque must be checked using a torque meter . Assembly T ools • All chisels, rivet sets and other accessories should be checked for cracks, excessive wear , or other physical damage before each use. Accessories that show signs of damage should be replaced immediately . • Never use a tool without the proper accessory retainer . Hammers • Always use accessories of correct size and design for the tool. T ool and accessories must not be modifed in any way . • Never use a tool without the proper accessory retainer . • Specifc instructions/warnings af fecting this group of tools are contained in product-specifc documents accompanying each product. • Never mount a grinding wheel on a sander . • Never use a grinding wheel marked with a speed lower than the rated air grinder speed. • All grinding wheels and polishing/sanding accessories should be checked for cracks or other damage before mounting and use. • Always use the recommended wheel guard to prevent injury when performing grinding operations. If a guard has withstood wheel or disc breakage, it must be replaced. • Position a guard between the grinding wheel or disc and the operator . Use barriers to protect others from fragments and grinding sparks. • Make sure grinding wheels are mounted according to manufacturer ’ s specifcations; always use correct mounting fanges. • Before grinding, test grinding wheel or disc by briefy running tool at full throttle. Be sure to use a barrier (such as under a heavy work table) to protect yourself from possible broken wheel parts. • Never tamper with or remove a speed governor from a tool to make it run faster . Periodically check tool speed with a tachometer . Abrasive T ools See Safety Requirements for Abraiding Materials with Coated Abrasives (B7.7) from ANSI. • Keep away from rotating bit and chuck. y ou can become cut or burned if you come in contact with the drill bit, chips or work surface. • Use intermittent drill pressure to avoid long shaved chips. • The drill bit can suddenly bind and cause the work piece or tool to rotate causing arm and shoulder injuries. • ANSI recommends use of a support handle on drills with a chuck larger than 3/8" (10 mm). • Never use hand sockets. Use only power drive sockets per ANSI B107.2. • T o reduce the risk of injury , always support the handle securely in the direction opposite of the spindle rotation to minimize torque reaction.
