REPLACEMENT OF HYDRAULIC OIL ANDFILTERMAINTENANCEChange Hydraulic Oil and Replace Hydraulic Oil Tank FilterHydraulic breaker operation subjects the hydraulic systemto become contaminated faster and to quickly deterioratethe hydraulic oil. For this reason, hydraulic oil must bechanged and the hydraulic oil tank filter must be replacedmore often than the machine equipped with a bucket. FailChanging intervals (Hours)ure to do so may result in damage to the breaker,hydraulic oil pump, and other related hydraulicsystem components. Recommended changingintervals are shown below.
