Diagnostic overview

Likely Root Causes

- Blade is dull or the feed load is excessive
- Battery is hot, cold, low, damaged, or unsuitable
- Cut depth, support, or material is overloading the saw
- Motor, bearing, controller, or battery fault
Quick Checks
- A light supported cut completes without abnormal heat or shutdown.
Repair Preview
- Release trigger, remove pack, and place both on a clear surface.
- Let saw and pack cool naturally, then brush the vents and inspect for damage or odor.
- - Fit sharp blade and good pack - correct depth and support - test lightly.
