Put tool number 22 into the hole of hook 12. Loosen the Allen screw in the tool holder 11 and fasten tool number 23. Put the two eyelet parts in the skate with the light part from the inside and the dark part from the outside. Position the skate above the hook 12 such that you feel that tool number 22 fits the inner part of the eyelet. Similarly lower the tool holder 11 so that tool number 23 fits the outer part of the eyelet. Press firmly and the riveting is done.
