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.

• 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

1. With the battery removed, the lower guard moves freely without blade contact and snaps closed promptly at every tested depth and bevel position.

1. Remove the battery immediately and do not use the saw while the lower guard is missing, tied open, slow, damaged, or contacting the blade.
2. 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.
3. - 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
4. Confirm a correct centered blade and clean clamp area, and do not lubricate the guard/clamp region.
5. 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.
