Troubleshooting

The cause of an improperly functioning hydraulic sys- tem is best diagnosed with the use of proper testing equipment and a thorough understanding of the com- plete hydraulic system.

A hydraulic system with an excessive increase in heat or noise is a potential failure. Should either of these conditions be noticed, immediately stop the machine, turn off the engine, locate the cause of the trouble, and correct it before allowing the machine to be used again. Continued use of an improperly functioning hydraulic system could lead to extensive internal component damage.

The charts that follow contain detailed information to assist in troubleshooting. There may possibly be more than one cause for a machine malfunction. All causes should be checked in the order in which they are listed on the charts; do not deviate from this procedure.

Refer to the Testing section of this Chapter for precau- tions and specific test procedures.
