诊断概览
弹簧加载的下护罩无法自由移动至所有角度/深度,关闭不及时,摩擦锯片,或普通切割时需手动辅助。
可能根本原因
- 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
快速检查
- With the battery removed, the lower guard moves freely without blade contact and snaps closed promptly at every tested depth and bevel position.
维修预览
- 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.
