8.7.7 Visual inspection of the axis system (electrics)
DANGER
Severe or fatal injury from hot machine! Hot pot containing molten metal!
ü For any work being carried out, take the following safety precautions:
a) Touching the pot during operation is forbidden!
b) Allow the pot to cool down to room temperature before carrying out service and
cleaning work! On this regard, observe the solder temperature at the machine
terminal!
c) During the solder heating and cooling, molten metal can splash out of the pot!
The machine protective plates must therefore remain closed during heating and
cooling!
d) Open protective plates only when the solder has solidified completely.
e) Service and cleaning work on hot pots must always be carried out by trained and
qualified personnel!
