s6, tool resetting: promote the fan-shaped briquetting of multiunit and remove to the direction of keeping away from the centre of a circle, put into fan-shaped cushion in the annular tang on the mounting panel, use the mounting with the base, fold and press child, footstock and connect according to the original position and can continue to carry out the pressure of laminating of next stator core.
