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 tempe-
rature 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 permit-
ted 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 4.8.
• All Spherical Roller Bearings (SRBs) are subjected to a special heat
treat-ment. 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 4.8
to determine the correct power setting.
• 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 demagneti-
ses 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.
• Always wear protective gloves and other appropriate protective equip-
ment when removing the hot workpiece. NB: Risk of burning. The workpi-
ece may also be removed using suitable handling equipment.
• If the workpiece remains on the heater, the heater will start again when
the temperature of the workpiece drops 10°C (18°F). Press START/STOP
to stop the heater and demagnetise the workpiece.
• The device is now ready to heat another workpiece with the same settings.
