Makita 231878-2 Spare Part - TENSION SPRING 4 HS6100/DHS68
Original Makita tension spring 231878-2 — direct-fit guard/return spring for select 165 mm circular saws. This small, heat-treated spring-steel coil restores the correct tension and return action of the lower blade guard so the guard lifts and snaps back smoothly during cuts.
Key details
- Part: Makita 231878-2 (tension / guard return spring).
- Function: guard/return (restoring) spring that keeps the lower guard returning to its closed position and maintains correct linkage tension.
- Construction: spring-steel coil made to Makita’s original specifications for length, coil rate and end form so it installs and performs like the original.
Example models it fits
- Makita DHS680 (DHS68) cordless 165 mm circular saw.
- Makita HS6100 and HS012G (similar 165 mm circular saw models reported to use the same guard spring).
Why this part matters
- A fatigued or broken guard spring causes sluggish or stuck lower-guard movement, which can compromise cutting convenience and safety; replacing it restores smooth, predictable guard operation.
Notes
- Sold individually and intended as a direct replacement for the listed Makita models; simple to swap with basic hand tools during a guard/maintenance service.
