Measures required in case of incorrect readings 99 Foreword The purpose of this service manual is to assist you in quick and correct repair of the machines. Adjustments should only be made if the settings deviate from the requirements described in this manual. When checking or adjusting a machine, always proceed in the order of the worksteps prescribed. For easier reference, each workstep is identified by a number. Different operational procedures are indicated by a circle or a square. The indications "left", "right", "top", "bottom", "front" and "back" always refer to the upright machine with the controls facing the operator. When assembling dismantled machines, adjust the machine to approximately the right settings. This facilitates the subsequent fine adjustments. Unless otherwise specified, the handwheel must always be turned forward. When carrying out maintenance work on live parts or in their proximity, the machine is to be separated from the power supply by disconnecting the lead cord from the electrical socket. An electrical safety test must be carried out after all repair work, even if the repair work is of a mechanical nature. The required electrical tests for the appliances are laid down in the current EU regulations, EEC directives, and the EMC-law (Standard EN 60335-1/A: 96 = ICE 335-1: 91/A1:94, mod). It is obligatory to perform a safety test in accordance with VDE 0701-1 after repair, modification and testing of electrical appliances. Outside Germany there are similar regulations in force which are largely identical with the requirements of VDE 0701. It is therefore necessary to consult a specialist when carrying out repairs on electrical appliances. For the proper adjustment of the machine, the follo...
