TO INSTALL THE CONNECTING CHAIN
1. Remove sprockets and chain guard back
plate as necessary so conveyors can be
connected together.
2. fasten conveyors together with butt cou-
plings and pivot plates. (figure 4C, Page 4)
3. Attach chain guard back plate to bottom of
conveyor frame. (figure 10B)
4. Install sprockets and keys on shafts and
align by placing straight edge across the
face of both sprockets. (Ref. figure 9C)
Adjust as needed and tighten set screws.
5. Install chain around sprockets and insert
connecting link. (figure 10A, detail "A")
Tighten chain by adjusting take-up block.
Note: If conveying in one direction only,
position take-up block on slack side of chain.
If conveying in both directions, position take-
up block at bottom of chain as shown in
figures 10A and 10B.
6. Install chain guard front plate.

1) Check for overloading of conveyor.
2) Check heater or circuit breaker and change if necessary
1) Replace chain and sprockets. Provide adequate lubrication.
NOTE: If problem reoccurs, a chain take-up may be required.
2) Align sprockets. See "drive Chain Alignment and Tension".
3) Tighten chain.
1) Replace bearing.
2) Tighten set screw.
3) Tighten chain.
1) Check capacity of conveyor and reduce load to recommended level.
2) Refer to "Pressure Adjustment" section. (Page 6)
3) Have electrician check and correct as necessary.
4) Relubricate per manufacturer's recommendations. for HYTROL reduc-
er, refer to separate manual.
5) Re-position take-up sheaves further from double groove sheave.
1) Check capability of conveyor and reduce load to recommended level.
2) Re-position take-up sheaves closer to double groove sheave.
3) Loosen spring tension on pressure rollers. (Page 7)
1) Tighten spring tension on pressure rollers in area of stalled rollers.
(Page 7)
2) Loosen bolt and adjust spring tension as required. Check for burrs or
foreign material behind angles.
3) Replace and re-adjust.
