not exceed 5 bar (70 psi).
18. Do not keep any highly inflammable
substances within the immediate vicin-
ity of the device.
19. Authorized operators: The operator
of the device must make the operating
instructions accessible to the operator and
must also make sure that s/he has read
and understood them. Only then may the
