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:
• Initial hydraulic filter maintenance must be carried out
after first 150 hours.
• Hydraulic oil return filter must be replaced every 250
hours with a breaker operating rate above 50%.
• Change the hydraulic oil according to the change
interval shown in the chart.
