SAFETY SA-1 RECOGNIZE SAFETY INFORMATION These are the SAFETY ALERT SYMBOLS. When you see these symbols on your machine or in this manual, be alert to the potential for per- sonal injury. Follow recommended precautions and safe oper- ating practices. 001-E01A-0001 SA-688 UNDERSTAND SIGNAL WORDS On machine safety signs, signal words designating the degree or level of hazard - DANGER, WARNING, or CAUTION - are used with the safety alert symbol. DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. DANGER or WARNING safety signs are located near specific hazards. General precautions are listed on CAUTION safety signs. Some safety signs don't use any of the desig- nated signal words above after the safety alert symbol are occasionally used on this machine. To avoid confusing machine protection with personal safety messages, a signal word IMPORTANT indi- cates a situation which, if not avoided, could result in damage to the machine. NOTE indicates an additional explanation for an element of information. 002-E01A-1223 SA-1223
