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.
