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.

Preventive Maintenance and Adjustment
Required Tools
• 8 mm wrench
• 10 mm wrench
• 13 mm wrench
• Level
• Torque wrench
Checklist
• Keep critical service parts on hand. Refer to the "Service
Parts" section starting on page 29 for recommendations.
• Clean entire conveyor while disassembled
• Replace any worn or damaged parts.
Cleaning
Use Dorner Belt Cleaner. Mild soap and water may also be
used. Do not soak the belt.
For /05 woven polyester and /06 black anti-static belts, use a
bristled brush to improve cleaning.
Lubrication
Conveyor Bearings
No lubrication is required. Replace bearings if worn.
Return Rollers
No lubrication is required. Replace rollers if worn.
Maintaining the Conveyor Belt
Troubleshooting
Inspect conveyor belt for:
• Surface cuts or wear
• Stalling or slipping
• Damage to V-guide
Surface cuts and wear indicate:
• Sharp or heavy parts impacting belt
• Jammed parts
• Improperly installed bottom wipers (if installed)
• Accumulated dirt in wipers (if installed)
• Foreign material inside the conveyor
• Improperly positioned accessories
• Bolt-on guiding is pinching belt
Stalling or slipping indicates:
• Excessive load on belt
• Conveyor belt or drive timing belt are not
properly tensioned
• Worn knurl or impacted dirt on drive pulley
• Intermittent jamming or drive train problems
Damage to V-guide indicates:
• Twisted or damaged conveyor frame
• Dirt impacted on pulleys
• Excessive or improper side loading
NOTE
Proper conveyor application, cleaning, and
sanitation are the responsibility of the end user.
CAUTION
Dorner recommends cleaning all the “food
zones” prior to placing conveyor into
service. Ensure adequate access is provided
for cleaning and servicing equipment so that
the required level of hygiene can be
maintained.
