How to Break Out Rivets
1. Determine the appropriate anvil and anvil slot for the pitch of
your saw chain.
2. Insert the saw chain to be broken into the proper slot of the
anvil, then push it forward until the bottom tie-strap is flush
with the far side of the anvil slot.
3. Drive links should be supported on both sides of the slot,
as shown.
3. Insert the portion of the saw chain for breaking into the
proper slot of the saw chain anvil and push saw chain forward
until the bottom tie-strap is flush with the far side of slot. (The
drive link will then be supported on both sides of the slot.)
4. Position the rivet head directly under the punch. When
breaking the saw chain at a cutter, make sure the cutter is in
the top position on an anvil as shown below.
5. If you are using a bench model chain breaker, pull the handle
of the chain breaker down. If you are using a handheld punch,
center the punch on the rivet head and strike the punch.
In either case, do not use excessive force.
WARNING: To reduce risk of injury, wear eye protection
and gloves.
