MAINTENANCE
Expendables
Replace expendables such as filters and elements periodically, referring to the table below.
Replace the hydraulic oil regularly!
¡ When using a hydraulic breaker, the oil deteriorates quicker than during normal digging.
Be sure to replace the hydraulic oil and return filter element.
• Failure to replace these in time can lead to damage to the machine and breaker’s hydraulic
systems. In order to improve the service life of the hydraulic systems, be sure to replace
the hydraulic oil and return filter element after the number of hours shown on the diagram
below.
• Clean the suction strainer when changing the return filter element.
