In general, it is convenient to keep your equipment filters in good condition, and even more the hydraulic ones, since it is in this system where the hardest work is concentrated, and it is the one which demands the highest effort from the equipment. Every element which accentuates the wear of the hydraulic system is actually reducing the efficiency of the machine, and thus, increasing the work cost. It is therefore advisable to replace the hydraulic filters as often as necessary. And this applies to any type of heavy equipment: excavators, backhoe loaders, bulldozers, loaders, dump trucks, graders, pavers, tunnel boring machines etc.
