What kind of problem is it?

Find it in the symptom index.

There are two symptom indexes in the Troubleshooting section. One is arranged alphabetically by

fault symptom

and the other is arranged alphabetically by

subject/symptom.

The symptom causing

the problem might be in the Troubleshooting Fault Symptom Index under Material Handling Crane

or Hydraulic System. In the Subject/Symptom Index, it might be under Remote Controller, or Crane.

When the symptom to the problem is found, go to the troubleshooting procedure page listed for

that symptom. For example, look for “Remote Controller will not operate crane.”

How can the cause of the problem be determined?

Go to page 2-83.

Troubleshooting for CRANE WILL NOT OPERATE MANUALLY OR WITH REMOTE CONTROLLER is

on that page. The troubleshooting procedures have columns with the headings: MALFUNCTION,

TEST OR INSPECTION, and CORRECTIVE ACTION. Starting at step 1, read the procedure. Each

step describes what to do and what to look for. Follow the steps, in order, to troubleshoot the

symptom until the problem is found. When the problem is found, the CORRECTIVE ACTION

column will describe how to fix it.

Let’s assume it was determined that the two-way solenoid valve is bad. The

replacement is in paragraph 17-32.

The procedure contains all the information needed to replace the two-way solenoid valve. First,

check the introductory material. It tells what will be needed before starting the job. Following the

introductory material is an exploded-view illustration and step-by-step instructions which show

how to remove and install the two-way solenoid valve.
