HYDRAULIC BREAKER
REPLACING THE HYDRAULIC OIL
REGULARLY
When a hydraulic breaker is used, the oil
deteriorates more quickly than that used for
a usual operation. Be sure to replace the
hydraulic oil and the return filter elements.
• Failure to replace these in time can lead to
damage to the machine and the breaker
hydraulic system. 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.
• When replacing the hydraulic oil, clean the
suction strainer.
( ): When using conventional antiwear
hydraulic oil.
When the breaker operating ratio is 100%.
