Warnings – General Safety
ADANGER
SEVERE HAZARD!
KEEP OFF CONVEYORS. Climbing, sitting,
walking or riding on conveyor will result in
death or serious injury.
ADANGER
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.
AWARNING
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.
AWARNING
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.
AWARNING
SEVERE HAZARD!
LOCK OUT POWER before removing guards
or performing maintenance. Exposed moving
parts can cause serious injury.
AWARNING
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.
AWARNING
PUNCTURE HAZARD!
Handle drive shaft keyway with care. It may
be sharp and could puncture the skin,
causing serious injury.
AWARNING
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
• 17 mm wrench (or adjustable wrench)
• 4 mm hex wrench (for bearing shaft assembly fasteners)
• 3 mm hex wrench
• Punch and hammer (to remove belt rod)
Checklist
• Keep service parts on hand. Refer to the "Service Parts"
section starting on page 28 for recommendations.
• Replace any worn or damaged parts.
Cleaning
Routine Cleaning
Dorner recommends cleaning the inside and the outside of
the conveyor on a daily basis. Refer to the following steps to
access the inside of the conveyor.
Standard Conveyors
1. Remove the guides, if applicable, by removing the pull
pins (Figure 46, item 1) that connect the guide
(Figure 46, item 2) to the frame.
Figure 41
2. Remove the pull pin (Figure 42, item 1) on the tension
end of the conveyor to release belt tension.
Figure 42
3. Lift up on the belt (Figure 43).
Figure 43
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.
AWARNING
SEVERE HAZARD!
LOCK OUT POWER before removing guards
or performing maintenance. Exposed moving
parts can cause serious injury.

Conveyors with Tip Up Tails and Lifters
1. Remove the guides, if applicable, by removing the pull
pins (Figure 46, item 1) that connect the guide
(Figure 46, item 2) to the frame.
2. Use the lifter handle (Figure 44, item 1) to raise the
lifters (Figure 44, item 2) and raise the tip up tail
(Figure 44, item 3).
Figure 44
Periodic Cleaning
Dorner recommends complete dissasembly of the conveyor
periodically for thorough cleaning.
For conveyor disassembly and reassembly instructions:
• Refer to “Conveyor Belt Replacement” on page 18.
• Refer to “Sprocket and Puck Removal” on page 21.
• Refer to “Reassembling Tail Assemblies” on page 24.
Lubrication
Conveyor Bearings
Conveyor bearing lubrication is required. Dorner
recommends using an H-1 food grade grease.
1. Add grease to the bearing using the zerk fitting
(Figure 45, item 1) on the exterior of the bearing shaft
assembly.
Figure 45
2. Replace the bearings if they become worn.
Wearstrips and Belt Returns
Replace the wearstrips and belt returns if they become worn.
For wearstrip and belt return installation instructions:
• Refer to “Wear Strip Installation” on page 11.
• Refer to “Belt Return Installation” on page 13.
Maintaining the Conveyor Belt
Troubleshooting
Inspect conveyor belt for:
• Surface cuts or wear
• Skipping
Damage to belt links or rods, surface cuts and / or
wear indicate:
• Sharp or heavy parts impacting belt
• Jammed parts
• Accumulated dirt
• Foreign material inside the conveyor
• Improperly positioned accessories
Skipping indicates:
• Excessive load on belt
• Worn sprockets or impacted dirt on drive pulley
CAUTION
DO NOT submerge or soak bearing
assemblies. This will reduce the life of the
bearing.
NOTE
Although bearings are sealed, re-greasing is
recommended to increase bearing life. An
H-1 food grade grease is recommended. The
frequency of bearing re-greasing is
dependent upon the application in which the
conveyor is being used. Frequency of re-
greasing will increase with the frequency of
conveyor washing.
