Hydraulic Breaker Maintenance Interval

Hydraulic oil breaks down faster on machines equipped
with a hydraulic breaker than on machines equipped with a
bucket. Follow the steps below to set the service intervals:
1. Initial hydraulic filter maintenance must be carried out
after the first 100 hours.
2. Hydraulic oil return filter must be replaced every 250
hours with a breaker operating rate above 50%.
3. Change the hydraulic oil according to the change
interval shown in the chart.
