DANGER
Do NOT OPERATE
CONVEYORS IN AN
EXPLOSIVE ENVIRONMENT.
Ç
Exposed moving parts can
cause severe injury.
LOCK OUT POWER before
removing guards or
performing maintenance.
WARNING

WARNING
Ç
Ç
Dorner cannot control the
physical installation and
application of conveyors.
Taking protective measures
is the responsibility of the

ment or as part of a multiple
conveyor system, CHECK
FOR POTENTIAL PINCH
POINTS and other mechani-
cal hazards before system
start-up.
WARNING
Ç
Ç
MPB Series Conveyors are
not reversible. Reversing
creates pinch points which
can cause severe injury.
DO NOT REVERSE MPB SE-
RIES CONVEYORS.
