CAUTION Place the mass spectrometer in Standby (or Off) mode before you open the
atmospheric pressure ionization (API) source. The presence of atmospheric oxygen in
the API source when the mass spectrometer is on could be unsafe. (The mass spectrometer
automatically turns off when you open the API source; however, it is best to take this
added precaution.)
CAUTION Follow the instrument maintenance instructions. To avoid personal injury or
damage to the instrument, do not perform any servicing other than that contained in the
TSQ Endura and TSQ Quantiva Hardware Manual or related manuals unless you are
authorized to do so.
CAUTION Use care when changing vacuum pump oil. Treat drained vacuum pump oil
and pump oil reservoirs with care. Hazardous compounds introduced into the system
might have dissolved in the pump oil. Always use approved containers and procedures for
disposing of waste oil. Whenever a pump has been operating on a system used for the
analysis of toxic, carcinogenic, mutagenic, or corrosive/irritant chemicals, you must
decontaminate the pump and certify it as free of contamination before a Thermo Fisher
Scientific field service engineer repairs or makes adjustments or before it is sent back to the
factory for service.
