Replacing the hydraulic filters and fluid when a hydraulic breaker is used (optional)
When using the hydraulic breaker, hydraulic fluid deteriorates more quickly than during ordinary digging. Check the
hydraulic fluid level more frequently. In addition, when changing the filters, also check the condition of the hydraulic
fluid.
Using the following graph as a reference, determine the intervals for changing the hydraulic fluid and filters, depending
on the frequency of use of the hydraulic breaker.
