To check drive 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.
Check drive chain for kinks, broken or bent
links or other damage. Check motor
sprocket and drive sprockets (on drive
shaft); tighten setscrew on flat of shaft if
required. Check for damaged/worn sprock-
ets and replace as required.
Check all electrical connections for burns,
discoloration or arcing. Replace all connec-
tions or components with damaged termi-
nals. Replace all damaged wiring with the
same (or higher) rated wire.
Remove conveyor belt (page 13). Replace
entire belt if links are damaged. If conveyor
belt has too much play, it will jam. Adjust
belt length as described under Servicing the
Conveyor Belt (page 13).
Measure bun thickness and set bun adjust-
ment controls correctly (page 7).
Confirm platen temperature reading with a
pyrometer or other temperature source.
Check receptacle for correct voltage. See
Specifications (page 4).
With unit plugged in and rocker switch on,
check for correct voltage into rocker switch.
If low or zero voltage, replace power cord.
If voltage is correct, check for correct volt-
age out of rocker switch. If low or no volt-
age, replace rocker switch.
Check all electrical connections for burns,
discoloration or arcing. Replace all connec-
tions or components with damaged termi-
nals. Replace all damaged wiring with the
same (or higher) rated wire.
