Like most electrical and non-electrical appliances, the shredder also needs careful maintenance. In this case it is simple and does not require the use of special products. One way to ensure long product life and a consistent performance is to use lubricated sheets to help preserve the motor and cutting blades. The best models often come with a self-lubricating mechanism, which allows the appliance to clean the components automatically and without inserting anything from the outside. To keep the machine in excellent condition and avoid jams it is therefore necessary to oil its mechanical components.
