3. Add fresh oil.
a. Add fresh oil to the reservoir until the oil is half way between the MIN and MAX
level marks.
b. If the oil level goes above the MAX level mark, remove the drain plug and drain the
excess oil from the pump.
4. Reassemble the rotary-vane pump.
a. Replace the oil filler plug.
b. Return the rotary-vane pump to the floor.
c. Reconnect the foreline vacuum hose to the rotary-vane pump.
d. Plug in the rotary-vane pump and the mass spectrometer.
e. Restart the system.
Components and assemblies are located in four sections, the front cover, the left cover, the
right cover, and behind the mass spectrometer.
Note Keep the mass spectrometer packing materials in case defective parts must be
returned to Thermo Fisher Scientific.
CAUTION INSTRUMENT DAMAGE. Only use fuses specified in
fuse with a fuse of a different type, voltage, or current rating. Fuses protect circuits by
opening the circuits when an over-current occurs.

Replace a fuse only when indicated by the Tune Diagnostics, Thermo Fisher Scientific
Technical Support, or a Thermo Fisher Scientific Customer Service Engineer.
CAUTION INSTRUMENT DAMAGE. Avoid damaging the PCBs with electrostatic
discharge by attaching a properly grounded electrostatic discharge (ESD) strap to your
wrist before replacing fuses.
