Operating Instructions; Dismounting - SKF EAZ Mode D'emploi

6. Operating instructions

Before proceeding with mounting or dismount rings,
please take the following into consideration:
• Cracked rings must not be heated with the
electrical induction heater.
• The tool must not be switched on without the
steel ring in the bore! Otherwise the current
consumption increases considerably, and the
coil is heated too rapidly.
• Additional safety is provided by an automatic
cutoff interrupting the current as soon as
the temperature of the induction coil winding
exceeds 120 °C (248 °F). This situation may
also occur after several operations in a row. In
this case, it is recommended to cool down the
device with compressed air or a fan. To prevent
this from happening, remove the hot rings as
quick as possible from the inside of the heater.
This will signiicantly increase the duty cycle of
the heater.
• During dismounting, the roll neck must be
connected to earth, for example by means of a
single core cable with magnetic clamp or via de
support.
• Do not leave the heater unattended, especially
in Time Mode. The temperature needs to be
monitored to avoid damages.
