Maintenance

Use of Service Paks

Service Paks include all genuine parts needed for normal
maintenance of both compressor and engine. Service Paks
minimize downtime and keep your maintenance budget
low. You may order Service Paks from your local Atlas
Copco dealer.

Preventive Maintenance Schedule For 
The Compressor

The schedule contains a summary of the maintenance
instructions.

Read the respective section before taking maintenance
measures.

When servicing, replace all disengaged packings, e.g.
gaskets, 0-rings, washers.

For engine maintenance refer to Engine Operation
Manual.

The maintenance schedule has to be seen as a guideline for
units operating in a duty environment typical to
compressor applications. Maintenance schedule can be
adapted depending on application environment and
quality of maintenance
