Scheduled Maintenance Programs:  Customer Support Agreements (CSA)

A CSA is any arrangement between you and your Cat Dealer that helps you lower your cost per unit of production. Agreements are tailored to fit your business needs and can range from simple Preventive Maintenance Kits to sophisticated Total Cost Performance Guarantees. No matter which option you choose, you can be assured that your Cat Dealer will provide you with careful planning and ongoing attention that will help you succeed.  For more information, click here.



When you have HOLT® Scheduled Maintenance (also known as a Customer Support Agreement, or CSA), you can be sure that your generator sets and electrical components are being serviced using Caterpillar's® manufacturing standards, which are some of the industry’s highest standards. They are your guarantee of continued high quality performance and longer equipment life.
