Insert the rivets through the underside of the nose .
4 . With the guide bar
body, nose, and rivet

peen the rivet's head
down with the flat end of
a hammer . Do not hit the
guide bar body; hit only
the rivet head . To check
installation, grip the guide
bar body in one hand and
twist . The nose and body
should feel like a single,
solid piece . If you feel any
movement in the nose guide bar joint area, or if you hear any
clicking sounds from the same area, tighten the rivet with a
few more hammer strokes .
