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
SEVERE HAZARD!
KEEP OFF CONVEYORS. Climbing, sitting, walking
or riding on conveyor will result in death or serious
injury.
A
WARNING
SEVERE HAZARD!
LOCK OUT POWER before removing guards or
performing maintenance. Exposed moving parts
can cause serious injury.
A
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.
A
WARNING
PUNCTURE HAZARD!
Handle drive shaft keyway with care. It may be
sharp and could puncture the skin, causing serious
injury.
A
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.
A
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.
A
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.
A
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.

not soak the belt.
For /05 woven polyester and /06 black anti-static belts, use a
bristled brush to improve cleaning.
Conveyor Belt Replacement
Conveyor Belt Replacement Sequence
• Release tension
• Remove old conveyor belt:
- Conveyor without Stands or Gearmotor Mounting
Package
- Conveyor with Stands and Gearmotor Mounting
Package
• Install new conveyor belt
• Tension conveyor belt
