This breaker has passed strict tests and inspections before delivery. However, if using the breaker
forcibly at the beginning, the functions will be effected and its service life will be shortened. Carry out
running-in operation by paying attention to the following items for the initial 100 hours (the time
displayed by a service meter of the base machine).
• Warm up the base machine by idling for 5 minutes after starting the engine.
• Move the boom and arm for approx. 5 minutes after warm-up operation to raise the hydraulic oil
temperature.
• Break and dismantle without overstraining the machine while the throttle lever is at the
intermediate section.
