Warnings – General Safety
DANGER
SEVERE HAZARD!
KEEP OFF CONVEYORS. Climbing, sitting,
walking or riding on conveyor will result in
death or 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!
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.
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.
