General
When servicing, replace all removed gaskets, O-rings and washers.
Intervals
The local Atlas Copco Customer Centre may overrule the maintenance schedule, especially the
service intervals, depending on the environmental and working conditions of the compressor.
The longer interval checks must also include the shorter interval checks.
