Break-In; Breaking In New Machine - Hitachi ZAXIS 30U-5N Operator's Manual

Breaking in New Machine

IMPORTANT: Operating a new machine at full load
without first breaking in can cause scratches and/or
seizures, consequently affecting the service life of the
machine. Thoroughly perform break-in operation.
The service life and performance of the machine can be greatly
affected by operation and maintenance of the machine during
the initial stage of operation. Perform break-in operation with
the engine output less than 80% of the maximum output for
the first 50 hours.
