Product Manuals & Parts Diagrams
Find your trimmer's official manual to look up spool specs, line gauge, and part numbers. We link directly to manufacturer documentation — no sign-up required.
Why you need the manual before ordering parts
Your trimmer's owner's manual contains the exact spool part number, compatible line gauge (.065", .080", or .095"), and head assembly diagram. Ordering without checking the manual is the most common reason people get the wrong spool. Find your brand below, then search for your model number on the manufacturer's site.
Search by model number (e.g., P2008, RY40250). Manuals include spool specs and line gauge.
