Choosing the correct reference

The manufacturer's TODDA cover names both ZX290 variants. Compare the full LC or LCN designation and -5B suffix with the machine being serviced. The technical index separates pump, swing, travel, pilot-valve and control-valve operation, helping you find the relevant explanation before moving to tests or repair work. Circuit diagrams should be checked against the installed equipment and their applicability notes. Other publications sometimes listed alongside this series, including super-long-front operator material and optional circuit supplements, are separate from the document inventory shown here.
