4 Maintaining the MSD
One or two procedures in this chapter require access to the inside of the
MSD while the power switch is on. Do not remove any of the electronics
safety covers in any of these procedures. To reduce the risk of electric
shock, follow the procedures carefully.
If your instrument is equipped with the optional gauge controller, potential-
ly dangerous voltage also exists where the cable from the gauge controller
connects to the triode gauge tube. Turn off the gauge controller if you are
going to be working near the triode gauge tube.
Many parts are hot enough to be dangerous
Many parts in the MSD operate at, or reach, temperatures high enough to
cause serious burns. These parts include, but are not limited to:
• GC/MSD interface
• Analyzer parts
• Vacuum pumps
The GC injection ports and GC oven also operate at very high temperatures.
Use the same caution around these parts. See the documentation supplied
with your GC for more information.
