The adjustment of the ignition contacts is relatively easy. Remove the rubber plug from the pole wheel. Bring the piston to top dead center (pencil through the spark plug hole and determine the TDC by turning the pole wheel back and forth). Then bring the contacts to a distance of 0.4mm (feeler gauge, see Accessories). To do this, simply loosen the fixing screw of the contacts slightly and adjust the ignition contacts with the blade of a suitable flat screwdriver. Tighten and you are done.
