Service contracts
Atlas Copco offers several types of service contracts, relieving you of all preventive maintenance
work. Consult your Atlas Copco Customer Centre.
General
When servicing, replace all removed 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.
Service interventions
Following actions have to be done on a regular basis:
Maintenance checklist

Yearly or every
8000 hours (2)
Every 5 years or
40000 hours (2)

Apart from the above mentioned actions, the service interventions in the table below are
programmed in the memory of the Elektronikon™ controller. Each plan has a programmed time
interval at which all service actions belonging to that plan are to be carried out. When reaching
the interval, a message will appear on the screen indicating which service plans are to be carried
out. See section "Service menu" of the controller. After servicing, the intervals must be reset.
