Button Function
POWER Press to adjust the power in steps of 20%� The selected power is indicated on the power display�
MODE Press to switch between TIME MODE and TEMP MODE�
UP (+) Press to increase the value shown on the main display�
DOWN (-) Press to decrease the value shown on the main display�
START/STOP
Press to start or stop the heater� The LED on the START/STOP button is lit when the heater is heating and
flashes during temperature measurement�
5.3 Temp Mode
› If the main display shows “t”, press MODE to select TEMP MODE� The main display shows °C or °F in TEMP MODE�
› The selected temperature is shown on the main display� The default temperature for bearings is 110°C (230°F)� If a different
temperature is desired, press UP or DOWN to adjust the temperature in steps of 1°C (2°F)�
›
It may be desirable to heat bearings to temperatures above 110°C (230°F) for increased mounting time� Consult the bearing
specifications to determine the maximum permitted temperature� Always ensure the bearing does not lock due to an
excessive expansion of the inner ring compared to outer ring� See section 5�8�
›
All Spherical Roller Bearings (SRBs) are subjected to a special heat treatment� These bearings can be operated at temperatures
as high as 200°C (392°F)� Heating these bearings above 110°C (230°F) will not cause any damage as long as the bearing is
still able to rotate� For other bearings, a temperature of 125°C (257°F) must not be exceeded unless otherwise specified�
› Press POWER to select the power level� Use the guidelines in section 5�8 to determine the correct power setting�
› Make sure the temperature probe is mounted on the bearing inner ring�
› Press START/STOP to start the heater� The main display shows the current temperature of the workpiece�
› When the selected temperature has been reached, the heater demagnetises the workpiece, switches off and generates an
acoustic signal for 10 seconds or until START/STOP is pressed�
› Press START/STOP to stop the heater�
