1.5. Dangers

1.5.1. Physical Dangers

Moving machine parts such as the alignment station,
microscopes and their manipulators, the mirror
housing and others can cause injury to the operator.
You should take particular care of the movements of
the microscope if your machine is equipped with the
direct microscope view finder.
Warning!
Moving machine parts can injure the fin-
gers or face.
Do not remove any materials from the
machine until all machine movements
have stopped!
Warning!
With a machine equipped with a vibra-
tion-damped table, the base plate can
sink without warning in the event of a
drop in pressure in the compressed air
supply.
Never place the hands between the base
plate and the vibration-damped table of
the machine!

1.5.2. Thermal Dangers

The upper side of the lamp house gets very hot dur-
ing operation.
Operating temperatures of several hundred °C occur
on the lamp itself.
The lamp cooling must be correctly adjusted accord-
ing to the lamp type!
Warning!
There is a risk of lamp explosion if the
lamp house is opened prematurely
while the lamp is hot.
The exposure lamp has to cool down for
at least 20 minutes before the lamp
house door is opened!
The controlled cooling required for
more powerful lamp types must also be
left in operation during the cooling
phase!

1.5.3. Electrical Dangers

Live parts may be exposed when the machine cover
is removed.
High wattages and currents of up to 50 A can occur
in the lamp and lamp power supply.
The lamp starting voltage can be up to 30 kV.
