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

  1. 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

  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.
