Using this record
Match three things before you buy line: the model name on the rating plate, the head fitted to the tool, and the diameter in the table above. If the head has been replaced, this record may not apply; follow the instructions of the head you now have.
If the line does not fit or keeps breaking
- Line keeps breaking: separate normal wear from a head or loading fault.
- Not sure which diameter is on the spool: measure the line you have before you buy more.
- Not sure which head you have: identify the cutting head from the tool and its manual.
- Round, twisted or square line: why shape and diameter are separate choices.

How this record was checked
The diameter and part numbers are copied from the cited page or manual, not estimated or averaged across models. The record carries the date it was last checked. Manufacturers change specifications between production runs, so confirm the rating plate and the current manual before you buy.
Same model name, different product: regional versions can differ. Match the rating plate.
