PREFACE

SERVICE PREPARATION This manual provides the instructions for the replacement of all the components that may become worn or damaged during normal usage of the machine. “Illustrated Parts Lists” - For each machine give full details of the replacement part numbers with supporting diagrams to show the location of the components. “Service Instructions” - For each machine give the recommended servicing procedure with supporting pictorial diagrams for added clarity WARNING 1. Check the machine RATING PLATE DETAILS are compatible with the electrical

mains supply. 2. Disconnect the electrical mains supply before removing any covers. 3. The machine MUST have a sound Electrical Earth Connection. NOTE: THE ELECTRIC MOTOR IS PROTECTED BY AN AUTOMATIC THERMAL OVERLOAD CUT-OUT Product Testing after Servicing or Repair. IMPORTANT. If any electrical component has been changed, an electrical connection broken and remade, or any wiring disturbed, the product being repaired or serviced must be flash tested or PAT tested. This test must be carried before a product is handed back or returned to the customer or returned to stock. The test must be appropriate for the machine being repaired. E.g. double insulated or earthed. A competent person should conduct the test and keep a log of all machines tested, the serial number of the machine, the details of the test, the test results and the date the test was carried out.



DESCRIPTION

A range of straight and crosscut shredders using either built up or solid shafts. ANTI JAM FEATURE All models include an anti jam feature if documents above a set thickness are fed into the infeed slot. The documents will not have entered the cutters. The thickness is equal to the nominal sheet capacity of 70gsm paper. The documents can then be easily removed from the machine and sheets removed. The device will also stop the machine if an increase in document thickness is detected while shredding again allowing easy removal of the access sheets before they enter the cutters. The document thickness is measured by a trigger coupled to an accurate measuring sensor. A pair of rollers and servo operated pressure pads are incorporated to prevent movement of the paper, passing through the cutters, generating false signals. It is possible to reverse the machine if necessary.
