1. Check whether the electric chain saw is short of oil, which makes the chain dry and stuck, causing it unable to rotate normally.
2. Check whether the motor power supply is in place and connected.
3. Check whether there is a problem with the carbon brush of the motor. Poor contact of the carbon brush will also cause the electric chain saw to fail to rotate normally.
4. Check whether there is foreign matter stuck inside the motor.
