• Switch the machine on and press the time mode key 'π '. Press the '▲' or
'▼' key to set the desired time (by pressing the time mode key 'π ' 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 tempera-
ture 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 auto-
matically demagnetised and a loud continuous beeping is emitted. Press
the 'STOP' key to switch off the machine.
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 auto-
matically demagnetised.
• Using 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.
Malfunctioning
• If the temperature of the work piece fails to increase by 1º (either C or F)
within a set time-span, the heater switches off automatically. Four blink-
ing dashes will appear (----) in the display, and a loud intermittent beep is
emitted. Press the 'STOP' key to stop the beeping and check whether:
• the probe is still attached to the work piece, and is connected correctly
into its socket.
• the probe wiring has been damaged.
• the probe surface is clean.
• the heater capacity is too small for the work piece.
If the probe is defective, theTime Mode can still be used.The temperature
should be checked using an external thermometer.
