1.2 Product safety and dangers
The appliances described in this manual are technically sophisticated, manufactured using
high-quality materials and subject to many hours of testing in the factory. They contain the
latest technology and comply with recognised technical safety regulations. However, there are
still risks involved, even when the appliances are used as intended. These are described below.
Warning!
After removing covers, live parts may be exposed. You may receive
an electric shock if you touch these parts. Disconnect the mains plug
before removing any covers. Only electrical technicians may work on
the electrical equipment of the appliances.
Warning!
When loading the appliance with an unsuitable load, poisonous or
explosive vapours or gases may be produced. This could cause the
appliance to explode, and persons could be severely injured or poi-
soned. The appliance may only be loaded with materials/test objects
which do not form any toxic or explosive vapours when heated up
(see also page 11).
Warning!
If the door is open while the appliance is in operation, the appliance
may overheat and pose a fire hazard. Do not leave the door open
during operation.
Warning!
Depending on operation, the surfaces in the working chamber
and the chamber load may still be very hot after the appliance is
switched off. Touching these surfaces can cause burns. Wear heat-
resistant protective gloves or wait until the appliance cools down.
Warning!
In case of appliances of a certain size, you can get accidentally
locked in, which is life-threatening. Do not climb into the appliance!
