7.3.4 How to proceed in case of a pow er fail-
ure
As long as the machine is not powered, you do not
have access to the working chamber.
After a short power failure, restart the machine and
the CAM computer.
If you need to access the working chamber in case of
a longer power failure, perform an emergency open-
ing of the working chamber door.
7.4 Emergency opening of the w ork-
ing chamber door
WARNING
Crushing hazard and cutting
injuries if the working
chamber door is open
If the working chamber door is open during
machining, it will not protect users from bruises and
cuts.
Do not open or close the working chamber door
during machining.
Never operate the machine with the working cham-
ber door open.
Perform the emergency opening only if you are
authorized to do so and if you have received training
on it.
Activate the safety interlock immediately after com-
pleting your work in the working chamber.
CAUTION
Cutting injuries when
touching a rotating tool
If a power failure or a machine malfunction occurs
during machining, the spindle including the inserted
tool keeps rotating. If you touch the rotating tool, you
will suffer from cutting injuries.
Wait until the spindle has stopped rotating before
performing an emergency opening.
The working chamber door is equipped with a safety
interlock that only allows you to open the door when
the machine is powered. You can use the emergency
release of the working chamber door if the working
chamber door is permanently locked. There is an
opening for the emergency release at the right side of
the machine.
