First oil change after 500 operating hours Notes on further intervals -> 8.3
Clean surface with compressed air
The pump must be cleaned regularly. The interval depends on the degree
of contamination on the casing.
During cleaning, protective goggles and an FFP2 mask according to EN
149:2008 must be worn.
Clean oil cooler (XL K variant)
Do not remove dirt from the cooling fins with compressed air, but
preferably with the help of a vacuum cleaner.
Oil change
The oil seals the pump and improves the running characteristics. The use
of the oil in the compressor chamber results in direct contact with the
process gas. This contaminates the oil. The pump can no longer achieve
the required performance characteristics. The oil must therefore be
changed at regular intervals (depending on the pump type).
