6.1 Preventive maintenance schedule
Safety precautions
Before carrying out any maintenance, repair work or adjustment, proceed as
follows:
• Stop the unit.
• Press the emergency stop button.
• Close the air outlet valve and open the manual condensate drain valves.
• Switch off the voltage.
• Open and lock the isolating switch (installed by the customer).
• Repairs inside the start and speed regulation cabinet may only be carried out by
Atlas Copco.
• Wait at least 6 minutes before starting any electrical repairs as hazardous high
voltage remains on the condensers of the start and speed regulation unit for 6
minutes after the voltage is switched off.
The operator must apply all relevant Safety precautions.
Service agreements
Atlas Copco Customer Centres have a range of service agreements to suit your needs:

Contact your Customer Centre to agree on a tailor-made service agreement. It will ensure
optimum operational efficiency, minimize downtime and reduce the total life cycle costs.
Warranty-Product Liability

parts is not covered by Warranty or Product Liability.
Service kits
Atlas Copco Customer Centres will be glad to provide you with a wide range of service kits.
Service kits comprise all parts needed for servicing components and offer the benefits of genuine
Atlas Copco parts while keeping the maintenance budget low.
Regular checks
To ensure safe operation and long service life carry out following operations at the interval
(period or running hours) which comes first. The longer interval checks must also include the
shorter interval checks. The local Atlas Copco Customer Centre may overrule the maintenance
schedule depending on the environmental and working conditions of the compressor.
