Warnings – General Safety
WARNING
The safety alert symbol, black triangle with white
exclamation, is used to alert you to potential
personal injury hazards.
DANGER
SEVERE HAZARD!
KEEP OFF CONVEYORS. Climbing, sitting,
walking or riding on conveyor will result in death
or serious injury.
WARNING
SEVERE HAZARD!
LOCK OUT POWER before removing guards or
performing maintenance. Exposed moving parts
can cause serious injury.
WARNING
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.
WARNING
PUNCTURE HAZARD!
Handle drive shaft keyway with care. It may be
sharp and could puncture the skin, causing
serious injury.
DANGER
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.
WARNING
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.
WARNING
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.
WARNING
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 start-up.
• Failure to comply could result in serious injury.
