2.6 Checks by the Operator
Check all of the safety-relevant parts of the centrifuge at least once per month for
any visible signs of damage (e.g. cracks, corrosion). This applies particularly to
the following:
•
Concentricity of the motor shaft:
−
Visual inspection: Slowly rotate the rotor by hand without the rotor tie-
down screw. If the motor shaft does not turn around on a perpendicular
axis, the motor and motor shaft must be replaced.
−
Refit the rotor correctly after visual inspection (see 5.2.3 "Installation of
Rotors", page 30).
−
Auditory inspection: Check the unit for atypical running noises.
•
Screw connections
•
Rotors and accessories. (see 5.2.5 "Service Life of Rotors an Accessories",
page 32).
2.7 Instructions for Emergency Situations
•
If an emergency arises, actuate the emergency switch at the exit (if installed)
or in the room next door (see 4.2.3 "Fuses/Emergency Circuit Breaker on
Site", page 24).
Or:
•
Disconnect the main power plug.
Fire-fighting measures or measures for the containment of harmful emissions
depend on the local conditions and on the substances processed in the
centrifuge. Please be informed about the rules and regulations that are applicable
on-site.
2.8 Remaining Hazards
The centrifuge was built state-of-the-art and according to the accepted safety
rules. Danger to life and limb of the user or of third parties, or impairments of the
unit or other material assets cannot be completely excluded when the centrifuge
is used.
•
Use the centrifuge only for the purpose that it was originally intended for (see
1.2, page 11).
•
Use the centrifuge only if it is in a perfect running state.
•
Immediately eliminate any problems that can affect safety.
