Always keep these operating instructions together with the machine. Ensure that the operating instructions are with the machine when it is given to other persons. Contents 1. [. . . ] b) If use of a spacer ring or other intermediate part is specified and the part is supplied with the cutting disc, check to ensure that the part is fitted. Use clamps or a vice to secure the workpiece. The workpiece is thus held more securely than by hand and both hands remain free to operate the machine. d) Before use, check that the cutting disc has been fitted correctly and the clamping nut tightened. Then allow the power tool to run for 30 seconds under no load while holding it in a secure position. Switch off the power tool immediately if significant vibration or any other faults are noticed. Should this occur, check the entire system in order to determine the cause. e) Take steps to ensure that flying sparks from the power tool do not present a hazard, i. e. Adjust the position of the disc guard accordingly. f) Slits cut in loadbearing walls of buildings or other structures may influence the statics of the structure, especially when steel reinforcing bars or loadbearing components are cut through. Consult the structural engineer, architect, or person in charge of the building project before beginning the work. g) Guide the power tool carefully and make straight cuts in order to avoid jamming the cutting disc. h) Guide the power tool evenly and do not apply lateral pressure to the cutting disc. Always bring the power tool into contact with the workpiece at right angles. Do not attempt to alter the line of cut by applying lateral pressure or by bending the cutting disc while cutting is in progress. This presents a risk of damaging or breaking the cutting disc. 10 5. 4 Safety instruction for all operations 5. 4. 1 Electrical safety a) Before beginning work, check the working area (e. g. using a metal detector) to ensure that no concealed electric cables or gas and water pipes are present. External metal parts of the machine may become live, for example, when an electric cable is damaged accidentally. This presents a serious risk of electric shock. b) Check the machine's supply cord at regular intervals and have it replaced by a qualified specialist if found to be damaged. Check extension cords at regular intervals and replace them if found to be damaged. Do not touch the supply cord or extension cord if it is damaged while working. [. . . ] Have it checked by a trained electrical specialist. 17 Fault The power tool doesn't start. Possible cause The electronic restart interlock is activated after an interruption in the electric supply. The extension cord's conductor cross section is inadequate. The carbon brushes are worn. Remedy Switch the power tool off and on again. Use an extension cord with an adequate conductor cross section. [. . . ]
