OPERATING THE MACHINE
5-27
Breaker hour meter (1) is located in the operator’s cab on
the right control panel. This hour meter (1) operates when
the breaker pedal is depressed. Obtain the average breaker
operation ratio according to the following formula.
Average breaker operation ratio (%) = Breaker operation
hours/Excavator operation hours = (Present breaker hour
meter reading – Breaker hour meter reading when the breaker
was previously removed)/(Present hour meter reading – hour
meter reading when the breaker was previously removed)
In case the machine is fully engaged in breaker operation
(breaker operation ratio:100%), perform the maintenance of
hydraulic oil, the full flow filter element, and the breaker return
filter based on the reading of the breaker hour meter.
