The conveyor speed can be adjusted by your local Hobart service technician. For Model FT900 and FT900W, maximum speed is 12 feet-per-minute, FPM, (factory preset is 8 – 9 FPM). For Model FT900S, maximum speed is 6.3 FPM. Contact your local Hobart service office if your conveyor speed needs adjustment.

TROUBLESHOOTING

To restart after the motor is allowed to cool, press the gray manual reset button on the motor junction box (Fig. 34).
