4 Maintenance
4.1 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 Chicago Pneumatic dealer.
4.2 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
