Section II. DIRECT SUPPORT TROUBLESHOOTING PROCEDURES
a. The troubleshooting System Symptom Index (Table 5-l) lists common malfunctions which could be found
during operation of the Paving Breaker. Table 5-2 lists the malfunctions and is followed by a list of tests or inspections
which will help to determine corrective action to be taken. These tests, inspections and corrective actions should be
performed in the order listed. Operation of a deadline unit without a preliminary examination can cause further
damage to a disabled component and possible injury to personnel. By careful inspection and troubleshooting, such
damage and injury can be avoided. In addition, cause of faulty operation of a unit can often be determined without
extensive disassembly.
This manual cannot list all malfunctions that may occur, or all tests, inspections, and corrective actions. If a
b.
malfunction is not corrected by the listed corrective actions, notify your supervisor.
