First of all, the safe use of the shredder must follow the operating requirements in the instructions, and the cover of the general shredder will have a warning sign for the user to prevent human injury due to operating errors when operating the shredder. Secondly, for more safety, the shredder should also have the function of automatic power-off when the drum is opened, automatic overload protection function, and automatic overheating protection function of the motor, which not only ensure the safety of the user's electricity but also increase the service life of the shredder motor. Therefore, consumers should pay attention to whether they have these functions when purchasing.

The sound emitted by the shredder has always been a concern of consumers. Shock absorption and noise reduction have also been the concerns of many manufacturers in recent years. The shredders of regular manufacturers currently on the market have reached the human body in terms of noise. With regard to safety standards, consumers need not worry about this issue as long as they look for products from regular manufacturers.
