SECTION 3: PREVENTATIVE MAINTENANCE PREVENTATIVE MAINTENANCE The dishmachines covered in this manual are designed to operate with a minimum of interaction with the operator. However, this does not mean that some items will not wear out in time. Jackson highly recommends that any maintenance and repairs not specifically discussed in this manual should be performed by QUALIFIED SERVICE PERSONNEL ONLY. Performing main- tenance on your dishmachine may void your warranty if it is still in effect. The
