Finding the recommended oil filter part number in the user manual

1. Locate your generator's user manual using the product lookup tool on Generac.com.

2. Once the user manual is downloaded, open the manual in PDF viewing software (such as Adobe or a web browser).

3. Perform a keyword search for "oil filter", "filter", or "recommended oil filter" to find matching words in the document. Performing a keyword search will vary by device, but in Adobe Acrobat and most browsers that command is "Ctrl + F".
