1Safety instructions
!!! Observe the safety instructions during the installation, operation,
cleaning and maintenance of the Rühle cutting machine!
Hazard potentially causing irreversible injuries if disre-
garded.
Warning potentially causing serious injuries if disre-
garded.
Note
Warning of electrical power.
Pull the mains plug!
Warning of sharp object. (Risk of cutting)
Hazard from bursting hoses.
Warning of slipping hazard.
Warning of hot surface.
Warning of non-ionising radiation.
Non-ionising radiation is not specifically generated, but is only
emitted by the electrical equipment (e.g. electric motors, power
lines or solenoid coils) for technical reasons. In addition, the
machine has no strong permanent magnets. If a safety dis-
tance (distance field source to implant) of 30 cm is maintained,
the influence on active implants (e.g. cardiac pacemakers, de-
fibrillators) can be excluded with a high degree of probability.
1.1 Safety instructions
!!! A supervisor (responsible person) must be assigned to the machine!
This person must:
