The FG series includes the FG20-12, FG25-12, FG30-12, FG20H-12, FG25H-12, FG30H-12, FG20S-12, FG25S-12, FG30S-12, FG20SH-12, FG25SH-12, and FG30SH-12.

The H20 and H25 gasoline/LPG engines and the 4D94E diesel engine are all covered in this parts book, with separate sections for CARB-compliant models. The serial number ranges covered are 10001A and Up, 550001A and Up, and 550001AE and Up.

How This Parts Book Is Organized

Each section begins with an illustration immediately preceding the parts list for that assembly. The header at the top of each illustration page provides the figure number and the part or assembly name. Parts lists include five columns: Index (item number in the illustration), Part No. (the number to be used when ordering), Description (the name of the part, with dot notation indicating assembly hierarchy), Qty (the number of parts required per assembly), and Serial No. (the applicable serial number range).

Machine detail codes shown in parentheses throughout the book help identify which parts apply to which chassis model. For example, G1 covers FG20/25-12, G2 covers FG30-12, D1 covers FD20/25-12, and D2 covers FD30-12, with additional codes for the H, S, and SH variants. This system makes it straightforward to locate the exact part number for your specific forklift configuration.

The Cascade mast sections cover 2-stage and 3-stage mast configurations in detail, including main lift cylinders, free lift cylinders, outer uprights, intermediate uprights, inner uprights, carriages, hoist chains, load backrests, and mast installation accessories. These sections are organized by mast series and include recommended spare parts lists.
