Common symptoms
- Motor runs but blade stays still
- Saw cuts out under load
- The blade turns, but the saw feeds poorly, stalls in the kerf, burns the wood, splinters excessively, or overloads during an ordinary cut.
- The saw suddenly lifts, jumps toward the operator, climbs out of the kerf, or walks backward as the blade pinches or twists.
- The blade starts during battery insertion, the trigger remains stuck, or releasing the trigger does not de-energize the saw.
- The saw starts normally but stops, pulses, or loses power during a cut, especially when pushed or when the battery is moved.
- The motor can be heard running, but the blade remains still, starts late, or slips instead of tracking the motor.
- The blade runs off-center, touches the guard or shoe, produces unusual vibration, or makes a grinding sound.
