Description
Overview:
The Lock Off Lever for Makita BCS550 and BHS630, with OEM Number 419664-3, is a Genuine Makita replacement part that prevents accidental trigger activation on a range of Makita cordless tools. Manufactured from hard-wearing moulded polymer for strength and low weight, it interfaces with the trigger assembly to provide a positive lock-off action. This helps maintain safe operation on site and in the workshop. Designed for a precise, factory-spec fit, it restores correct safety function where the original lever is worn, damaged, or missing. Suitable across selected circular saws and other handheld tools, including the BCS550 and BHS630, it is a straightforward swap for the original part and supports reliable day-to-day use.
Key Features:
- Genuine Makita part (OEM 419664-3) for assured fit and function

Typical Applications:
