The 12v car impact wrench rotates freely inside and then engages the drive shaft. Is this normal?
A manager responded to this review
Yes, this is normal. The impact wrench has a new power transmission system built in. When the motor reaches the set speed, the lever will immediately hit the output shaft to generate impact. Torque is generated when a certain speed is generated, but this process is very short, only 2-3 seconds. The entire operation process of a 12v car impact wrench can be simply described as: from rotation to sniper, this process will generate torque, you will hear the impact.
