Makita 231821-1 Tension Spring for 5620D, 5621D, 5026D, 5036D, 5046D, 5630D, BSS610, BSS611, BSS610Z, BSS611Z Circular Saws

The Makita 231821-1 tension spring is a replacement mechanical component designed to restore proper blade guard operation in compatible Makita circular saws. This spring is part of the guard return system and helps return the safety blade guard to its protective position after each cut. Constructed from durable steel, the tension spring is designed to withstand repeated movement and maintain consistent tension during regular cutting operations. Over time the original spring may weaken, stretch, or break due to frequent use, which can affect the proper return of the blade guard and reduce operational safety. Replacing the worn tension spring helps restore smooth guard movement and ensures the saw operates as intended during cutting tasks. The Makita 231821-1 tension spring is compatible with several Makita circular saw models including 5620D, 5621D, 5026D, 5036D, 5046D, 5630D, BSS610, BSS611, BSS610Z, and BSS611Z, ensuring proper fit and reliable performance when servicing these tools.
