MAINTENANCE AND CLEANING Continued
4.Carefully remove the thermostat dial, not disturbing the dial setting..
5.Hold the thermostat shaft steady with a small flat blade screw driver.. Turn the calibration screw located inside the shaft clockwise to decrease the temperature and counter clockwise to increase the temperature.. NOTE: each ¼ turn of the screw will create a change of approximately 35° F (20°C)..
6.Replace the thermostat dial and repeat steps 1 though 3 to verify that the correct adjustment has been made..

Griddle
1.Use a test instrument with a special disc type thermocouple or a reliable surface type pyrometer.. NOTE: a drop of oil on the face of the disc will provide better contact with the plate..
2.Set all griddle thermostats to 350°F (177°C).. In order to allow the griddle temperature to stabilize, the thermostats must be allowed to cycle twice before taking a test reading..
3.Check the griddle temperature when the thermostat just cycles “OFF” by placing the thermocouple firmly on the griddle directly about the sensing bulb of the thermostat.. The reading should be between 335° F (168°C) and 365° F and (185°C).. If the reading is outside of these limits, calibrate as follows:
