| incorrectly | Be sure that ends of the hooks are facing down. | |
| Defective platen. | To check platen: | |
|
| Use an Ohm meter to test resistance of the platen heater | |
|
| (disconnect 1 wire to isolate heater). Correct cold resis- | |
|
| tance for heating element of platen are as follows: | |
|
| 120 Volts, 1750 Watts - 7.8 Ohms | |
|
| 208 Volts, 2550 Watts - 16.2 Ohms | |
|
| 230 Volts, 1900 Watts - 26.5 Ohms | |

| 208V/300 Watts. | |
| Defective or wrong drive | To check drive motor: | |
| motor. | 1.Measure resistance of motor coil. Replace motor if coil | |
|
| measures either open circuit or zero resistance. | |
|
| 2.Mark the drive motor sprocket and count the turns per | |
|
| minute. Correct drive motor speed is nine (9) turns per | |
|
| minute for | |

| Defective drive chain or | Check drive chain for kinks, broken or bent links or other | |
| loose | damage. Check motor sprocket and drive sprockets (on | |
| sprocket. | drive shaft); tighten setscrew on flat of shaft if required. | |
|
| Check for damaged/worn sprockets and replace as | |
|
| required. | |
| Wiring problem. | Check all electrical connections for burns, discoloration | |
|
| or arcing. Replace all connections or components with | |
|
| damaged terminals. Replace all damaged wiring with the | |
|
| same (or higher) rated wire. | |
| Conveyor belt too loose | Remove conveyor belt (page 11). Lay belt flat and count | |
| or missing links (41 links | links. Replace entire belt if links are damaged. If conveyor | |
| required when new). When | belt has too much play, it will jam. Adjust belt length as | |
| new, conveyor has 37 large | described under Servicing the Conveyor Belt (page 10). | |
