Rough Pump
Agilent 6475 Triple Quad LC/MS System User Guide 84
Use only the rough pump oil appropriate for your pump (AFV 60 gold oil for
Agilent MS40+). The use of any other oils can substantially reduce pump life
and will invalidate the pump warranty.
To add rough pump oil,
1 Put on clean chemical-resistant gloves.
2 Place the instrument into 'Standby' then 'Vent'.
3 Allow the rough pump to turn off automatically, this should take about 15
minutes.
4 Unplug all power cords from LC/MS instrument.
5 Unplug the rough pump.
6 Remove the fill cap on the rough pump.
7 Add new AFV 60 gold oil until the oil level matches the maximum mark. Use a
funnel.
Do not fill the oil over the maximum mark beside the oil level window.
8 Reinstall the fill cap.
9 Wipe off all excess oil around and underneath the pump.
