7. Operation
There are two modes of heating:
Temperature Mode: Time Mode :

Used for controlled heating up to the
desired temperature.

Used when you wish to keep the work
piece at the desired temperature for up to
15 minutes.

Suitable for batch production. If the time
taken to heat the work piece to the desired
temperature is known.

Emergency use if the temperature probe is
lost or defective. The temperature of the
work piece should be checked using an
external thermometer.
7.1 Using the Temperature Mode (Default mode whenever the machine is switched on)

Set up the work piece and probe according to the instructions in sections 5 & 6.

Switch the machine on. The display will show 100c (or 100F). Enter the desired temperature
t
o which the work piece will be heated up to using the ‘▲’ or ‘▼’ key (by pressing the
temperature mode key (

) you can choose between steps of 1º or 10º - this is the
same whether working in C or F).

Press the
‘START’
key. Heating starts and a soft buzzing sound will be heard.

The current temperature of the work piece appears on the display. When the desired
temperature has been reached, the display starts to blink and a loud beeping is emitted.
Unless you press the ‘
STOP
’ key, the
heat-retention function will keep the bearing at that
temperature for 5 minutes. The machine resumes heating after a temperature drop of 3º (C or
F). When the set temperature is reached once more the induction heater emits a loud beep.
Press the ‘
STOP’
key to switch off the machine.

Pressing the ‘
STOP
’ key always causes automatically demagnetisation.

The heating process or the heat-retention function can be interrupted at any time by pressing
the ‘
STOP
’ key.
7.2 Using the Time Mode

Set up the work piece and temperature probe according to the instructions in sections 5 & 6
(the temperature probe is only necessary if you want to check the temperature).

Switch the machine on and press the time mode key ‘  ‘. Press the ‘▲' or ‘▼’ key to set the
desired time (by pressing the time mode key '

' you can choose between steps of one
minute or one second).

Press the ‘ START’
key. Heating starts and a soft buzzing sound will be heard.

If the temperature key ‘

‘is pressed while heating, the current temperature is displayed for 3
seconds. After that the countdown is resumed.

During the heating process the set time runs to 00:00. When 00:00 is reached the induction
heater switches off. The work piece is then automatically demagnetised and a loud continuous
beeping is emitted. Press the ‘
STOP’
key to switch off the machine.
7.3 Work piece removal

After pressing the ‘
STOP
’ key, place the probe on the side of the vertical pole. Pressing the
‘
STOP
’ key always causes the work piece to be automatically demagnetised.

Using the supplied heat-resistant gloves grip the yoke with the bearing on it and place it on
a clean, heat-resistant surface. Mount the bearing immediately to prevent cooling. If using a
model with a swing arm, swivel the yoke with the bearing on it into the fixed, open position (at
45º). Slide the bearing from the yoke. Mount the bearing immediately to avoid heat loss.
