FM-24: The Lower Blade Guard Sticks, Closes Slowly, Contacts The Blade, Or Will Not Close
The spring-loaded lower guard does not move freely through all angles/depths, fails to close promptly, rubs the blade, or needs manual help during ordinary cuts.
Diagnostic overview
The spring-loaded lower guard does not move freely through all angles/depths, fails to close promptly, rubs the blade, or needs manual help during ordinary cuts.
Likely Root Causes
- Sawdust, gum, or a small cutoff is obstructing the guard path
- Guard, retracting lever, pivot, or spring is bent, worn, damaged, or misassembled
- Blade or clamp stack is wrong and contacts the guard
- Guard was tied open, lubricated, or damaged by impact
Quick Checks
- With the battery removed, the lower guard moves freely without blade contact and snaps closed promptly at every tested depth and bevel position.
Repair Preview
- Remove the battery immediately and do not use the saw while the lower guard is missing, tied open, slow, damaged, or contacting the blade.
- Use the retracting lever to move the guard through its full travel at several depth and bevel settings, checking for free motion and prompt spring closure.
- - Clear dry sawdust, gum, and small offcuts externally - inspect the guard, lever, pivot, spring area, blade, and clamp stack for bend, rub, damage, or wrong
- Confirm a correct centered blade and clean clamp area, and do not lubricate the guard/clamp region.
- If the guard does not close freely and promptly at every setting, keep the battery out and have the complete guard system repaired by authorized service.
