Original Makita Safety Cover — part number 419933-2 — engineered to replace the damaged blade guard on Makita 136 mm (5-3/8") cordless circular saws and restore the tool’s factory safety features.

Direct-fit compatible models include BSS500, BSS501, DSS500 and DSS501 (listed as the factory replacement for those 136 mm saws).

This genuine Makita safety cover (also referenced as item Ref. No. 54 in parts breakdowns) is made to the original shape and mounting points so it snaps into the saw housing without modification — it replaces worn, cracked or missing guards that expose the blade, helping prevent accidental contact and keeping the blade area covered during operation.

If you’re sourcing parts for power tools to get a single repair finished quickly, the 419933-2 is the correct, original Makita blade/shield replacement for the saw models above and is supplied as the factory-fit spare.
