Maintenance personnel and machine operators can easily be trained to recognize the signs and symptoms of impending hydraulic troubles. To benefit fully from maintenance experience, a system of good reports and records is essential. To provide some basic guidelines for the use and care of hydraulic systems, this chapter describes some general guidelines for operation, maintenance, and troubleshooting. Pipes must be separated from each other; two pipes that are touching will rub and be weakened, and in extreme cases may wear a hole through the pipe wall. Flexible hoses must be installed in such a way to prevent buckling, twisting, and abrasion. Periodically during the operation of any hydraulic equipment or system, it is prudent to make a number of checks on a regular schedule. Routine checks of the operating pressures will indicate whether or not the pump is maintaining its efficiency.
