Follower pin is seated on top of spring loaded plunger in holding fixture and a sudden release could eject cam follower. Failure to comply may result in injury to personnel. CAUTION Any pin hole burrs on cam follower surfaces must be removed prior to installing roller and pin to prevent scoring of roller bushing and pin.
