318143-7 supersedes older part numbers: 316563-9
Genuine Makita Safety Cover / lower blade guard — part no. 318143-7 — for the 235 mm circular saw 5903R. This original Makita metal guard replaces a bent, worn or missing lower/shield assembly and restores the saw’s intended blade coverage and return action; it’s formed to the factory geometry with the correct pivot and mounting hole pattern so it fits straight onto the 5903R without modification.
Specifically made for Makita 5903R circular saws (blade diameter 235 mm), the guard covers the rear/lower half of the blade and works with the saw’s existing rollers, pins and springs to provide smooth retraction during cuts. If your 5903R shows a damaged shroud or unreliable guard movement, this original Makita replacement restores safe operation.
