Restringing a Bump-Feed String Trimmer: Finding the Right Manual

Rewinding Trimmer Line on a Dual-Port Bump Head

Most bump-feed heads use a pre-wound spool that pops in/out, or a fixed spool you wind manually. The winding direction and line diameter are model-specific.

Quick Steps (Generic)

1. Remove head (usually twist counterclockwise).
2. Note line diameter (.065", .080", .095")—buy matching.
3. Cut two equal lengths (typically 10-15 ft each).
4. Insert ends into anchor holes; wind neatly, tightly, in direction of arrow on spool.
5. Leave 6 inches unwound; snap into head ports.
6. Reinstall head; bump to advance.

Pro Tip

Buy pre-wound spools for your model—eliminates winding frustration. Keep spare spools loaded.
