When performing repairs to the conveyor, it is important to remove or protect the
belt to avoid damage from welding sparks or from other tools.
Avoid using the belt for uses other than for what it was specified. If you need to utilize
the belt in a different application, consult the manufacturer first.
Conveyor Belt Tension Adjustment
Check the belt tension of the package conveyor occasionally to ensure that it is not
excessive, as this will cause unnecessary wear on the conveyor sprockets.
To check or adjust tension, shut off power to the tunnel, remove the drive end caps, and
loosen the two outer jam nuts on the drive end of the conveyor. Adjust the tensioning
bolts as required to for correct belt tension. (Belt should touch lower rails approximately
11 inches in from the outside edge of the leg). If there is no more adjustment available
through the tensioning bolts, a link can be taken out. To remove a link, loosen the belt
by removing two (2) pins. (Remove the plastic keeper tab on the end of the pin.)
Eliminate one row of links, pull the conveyor belt together, and reinsert one (1) l pin. A
new plastic keeper must be used to hold the pin in place.
To Check or Adjust Conveyor Chain Tension
1. Bring a roller to the three o’clock position (the
center of the end) of the idler end of the conveyor.
2. Shut off power to the tunnel, and then remove the
idler end caps.
3. Begin with the roller in the three o’clock position
and count the conveyor rollers. The seventh roller
should be evenly touching the conveyor starter
rails.
Replacing Conveyor Components
Caution!
Disconnect main power source before performing any
procedure to replace any conveyor component(s).
Roller Silicone Covering Replacement
1. Disconnect power to the machine.
2. Remove idler end caps, disconnect drive chain, loosen the four (4) bolts that hold
the drive motor and then, through the access hole, take the drive chain off the
drive motor sprocket.
