The impactor must not be used as a hammer!* Grease the fork crown seat lightly with bearing grease beforehand.* Use a suitable hammer when striking the top.Note: Check before installation that the crown race matches head tube inner diameter. If not, use the Cyclus Tools art. 720003 / art. 720004 / art. 720034 for milling the crown race seat of the fork.
