Note: When checking the replacement limit, future wear
up until the next inspection date must be taken into
account. If the chain dimension values are outside the
limit values 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
replacement must be documented in the inspection log.
