3 Warnings General Safety DANGER SEVERE HAZARD! KEEP OFF CONVEYORS. Climbing, sitting, walking or riding on conveyor will result in death or serious injury. DANGER SEVERE HAZARD! LOCK OUT POWER before removing guards or performing maintenance. Exposed moving parts can cause serious injury. EXPLOSION HAZARD! DO NOT OPERATE CONVEYORS IN AN EXPLOSIVE ENVIRONMENT. The electric gearmotor generates heat and could ignite combustible vapors. Failure to comply will result in death or serious injury. BURN HAZARD! DO NOT TOUCH the motor while operating, or shortly after being turned off. Motors may be HOT and can cause serious burn injuries. CRUSH HAZARD! DO NOT place hands or fingers inside the conveyor while it is running. DO NOT wear loose garments while operating the conveyor. Loose garments can become caught up in the conveyor. Failure to comply could result in serious injury. CRUSH HAZARD! SUPPORT CONVEYOR SECTIONS PRIOR TO LOOSENING STAND HEIGHT OR ANGLE ADJUSTMENT SCREWS. Loosening stand height or angle adjustment screws may cause conveyor sections to drop down, causing serious injury. PUNCTURE HAZARD! Handle drive shaft keyway with care. It may be sharp and could puncture the skin, causing serious injury. SEVERE HAZARD! Dorner cannot control the physical installation and application of conveyors. Taking protective measures is the responsibility of the user. When conveyors are used in conjunction with other equipment or as part of a multiple conveyor system, CHECK FOR POTENTIAL PINCH POINTS and other mechanical hazards before system startup. Failure to comply could result in serious injury. 750 Series Power Transfer Rev. A Dorner Mfg. Corp.
