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.
7.3 Temperature 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. To determine the
maximum permitted temperature, consult the specifications of
the bearing manufacturer. Always ensure the bearing does not
lock due to an excessive expansion of the inner ring compared
to the outer ring. See section 7.8.
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.
