Note: When checking the replacement limit, future wear
to the next checking date must be taken into account.
If the chain dimension values are outside the limit val-
ues specified in the table when checked, the chain has
reached its replacement limit and must be replaced by a
new one. The chain sprockets must also be replaced
together with the chain, as otherwise the new chain
will be subjected to increased wear. Each chain replace-
ment must be documented in the inspection log.
