Filter element
● Regularly replace all filter elements. However, when working in harsh conditions, the filter
element should be replaced in a shorter period based on the lubricating oil and fuel (sulfur
content) used.
● Do not reuse the filter element after cleaning it (filter element type). Replace with a new
one.
● When replacing the filter element, check if there are metal particles adhering to the old
filter element. If metal particles are found, please contact your Yuchai dealer.
● Do not open the packaging of the spare filter element before use.
Hydraulic system
● During and after work, the hydraulic system is at high temperatures. In operation, it is still
in high pressure state. Therefore, when inspecting and maintaining the hydraulic system,
make sure that the temperature has dropped and the pressure has released in the hydraulic
cylinder pipeline.
● When loosening plugs, screws, or hose connections, do not stand in front of the parts.
Before disassembly, gradually loosen to release the internal pressure.
● When inspecting or maintaining the hydraulic oil line, it is necessary to exhaust the air to
release the internal pressure.
● The inspection or maintenance of the hydraulic system includes checking the hydraulic oil
level, replacing the filter element, and refilling hydraulic oil.
● When disassembling the high-pressure hose, check for damage to the O-ring. Replace if
damaged.
● When disassembling parts in areas sealed with O-rings or gaskets, clean the mounting
surface and replace with new parts.
● When installing hoses, it is not allowed to twist the hoses or bend them into small diameter
rings, which will damage the hose and obviously shorten the service life of the hose.
