FIELD MAINTENANCE
TROUBLESHOOTING SYMPTOM INDEX
GENERAL
This section provides information for identifying and correcting issues which may develop when operating or
maintaining the 7 1/2 Ton Crane.
The index lists common symptoms which may occur and refers you to the proper work package for a
troubleshooting procedure.
This section cannot list all symptoms that may occur, nor all tests or inspections and corrective actions. If a
malfunction is not listed, or is not corrected by the listed corrective actions, notify your Maintenance Supervisor.
When troubleshooting a malfunction:
1. Question the operator to obtain any information that might help determine the cause of the problem.
Before continuing, ensure that all applicable operator/crew troubleshooting was performed.
2. Locate the symptom or symptoms in the Troubleshooting Index that best describe the issue. If the
appropriate symptom is not listed, notify your Maintenance Supervisor.
3. Go to the work package where the troubleshooting procedures for the symptom in question are described.
Headings at the top of each page show how each troubleshooting procedure is organized: Symptom,
Malfunction, and Corrective Action.
4. Perform each step in the order listed until the symptom is corrected and the item being inspected is
operational. Do not perform any maintenance task unless the troubleshooting procedure tells you to do so.

The headings in the troubleshooting procedures are defined as follows:
1. SYMPTOM. A visual or operational indication that something is wrong with the crane.
2. MALFUNCTION. Observable fault in component or system.
