10.6 Maintenance of the fore-line roughing pump SV40BI
WARNING
Vacuum pump oil can be extremely hot if the pump has been running for an extended
period of time. Used pump oil may contain residual contaminants from the samples or
sample matrix.
Always wear gloves when handling used pump oil, and take appropriate preca
utions
when disposing of it.
NOTICE
Do not mix the pump oil (LVO420) with other oils! The pump oil will immediately
harden when mixed with other oils.
The oil in the forevacuum pump SV40BI should be checked weekly. The pump oil must
be changed:
 Regularly every 12 months
 When the oil has become dark brown or black
 When the oil is viscous or resinous
Analytik Jena recommends the following synthetic pump oil: Perfluorinated polyether
(PFPE) Leybonol LVO420. Other pump oils are available for highly specialized
applications; for more information please contact the Analytik Jena customer service
department.
The connection for changing the oil of the pump is located very close to the base of the
device. To facilitate maintenance, place the pump about 10 cm above the floor.
