Warnings −General Safety
A
WARNING
The safety alert symbol, black triangle with
white exclamation, is used to alert you to
potential personal injury hazards.
A
DANGER
Climbing, sitting, walking or riding on
conveyor will cause severe injury. KEEP OFF
CONVEYORS.
A
DANGER
DO NOT OPERATE CONVEYORS IN AN
EXPLOSIVE ENVIRONMENT.
A
WARNING
Gearmotors may be HOT.
DO NOT TOUCH Gearmotors.
A
WARNING
Exposed moving parts can cause severe
injury. LOCK OUT POWER before removing
guards or performing maintenance.
A
WARNING
Conveyors are not reversible. Reversing
creates pinch points which can cause severe
injury.
DO NOT REVERSE CONVEYORS.
A
WARNING
Top and Bottom Mount Gearmotors must be
mounted as shown below.
Failure to do so creates pinch points which
can cause severe injury.
A
WARNING
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.
A
WARNING
Loosening stand height or angle adjustment
screws may cause conveyor sections to drop
down, causing severe injury.
