1) Unscrew the oil filter housing.
2) Remove the filter element.
3) Install the new O-ring in the groove of the filter head.
4) Before the installation of the new filter element, coat the filter seal surface with a layer of hydraulic
oil, and then put the filter element into the filter head.
5) Clean the filter shell and the soft magnets, not allowing the dirt, dust or water enter the oil filter
housing.
6) Tighten the filter housing and the filter head with the torque of 25-35Nm.
7) After connecting the pipelines, start the engine slowly. Keep it running continually for three to five
minutes to discharge the air in the system.
8) After stopping the machine on the flat ground, check the oil level, and if necessary, you need to
add the fuel. Please pay attention to that the oil level cannot exceed the required maximum oil level
limits.
■ The replacement cycle of the hydraulic oil and filter element when the accessories are being
used (such as hammer)
Use of hammer increases the pollution of the hydraulic system and accelerates the corrosion.
Compared with the digging device, the replacement cycle of the hydraulic oil and filter element also
should be shortened correspondingly, to avoid the damage to the hydraulic pumps and other hydraulic
components. Recommended replacement cycles are shown in the following form: (unit: hour)
Note: The system pressure should be adjusted appropriately according to the requirements of
the hydraulic hammer when you are using a hydraulic hammer.
