7.3 Changing lubricant
WARNING
Health hazard and environmental damage from toxic contaminated lubricant
Toxic process media can cause lubricant contamination. When changing the lubricant, there is a
health hazard due to contact with poisonous substances. Illegal disposal of toxic substances causes
environmental damage.
►
Wear suitable personal protective equipment when handling these media.
►
Dispose of the lubricant according to locally applicable regulations.
CAUTION
Scalding from hot lubricant
Danger of scalding when draining lubricant if it comes into contact with the skin.
►
Wear protective equipment.
►
Use a suitable collection receptacle.
Pfeiffer Vacuum recommends determining the precise service life of the lubricant in
the first operating year.
The usable life may deviate from the reference value specified depending on thermic and
chemical loads, or due to penetrating process media in gear and bearing chambers.
