Replacing saw bar tip:

1. Use a 6–8 mm drill bit and drill out the rivet heads that hold the harvester tip to the saw bar. Punch out the remainings of the rivets.
2. Remove the old tip and clean the guide bar‘s attachment area
3. Insert the new rivets from the underside. Place the saw bar on a solid, flat piece of metal and peen the rivet‘s head down with a flat-head hammer. Make sure that you file down the rails of the new tip to align with the rails of the saw bar.
