Why is the electric wrench lacking power?

[DeAugust]

There are several reasons why an electric wrench may lack power: Insufficient battery: If the electric wrench feels weak and lacks power, the first thing to consider is whether the battery is low. Try charging it fully before using it again. Rust and resistance: This universal small spray can is no stranger to anyone. It's a versatile rust remover that can be used on everything from satellites to screws. Spray WD-40 onto the rotating bearing part of the electric wrench for about 20 seconds. You can spray while observing and let the motor rotate at the same time. This will lubricate any rusted or resistant areas inside, solving the wrench's power issue.
