Step 1. LOCATE PROBLEM (SYMPTOM). Look under the column labeled “PROBLEM (SYMPTOMS)”. This column describes pos- sible symptoms that the machine may exhibit. Find the listing that best describes the symptom that the machine is exhibiting.

Symptoms are grouped into three main cat- egories: output problems, function prob- lems, welding problems.

Step 2. PERFORM EXTERNAL TESTS. The second column labeled “POSSIBLE AREAS OF MISADJUSTMENT(S)” lists the obvious external possibilities that may con- tribute to the machine symptom. Perform these tests/checks in the order listed. In general, these tests can be conducted with- out removing the case wrap-around cover.

Step 3. PERFORM COMPONENT TESTS. If you have exhausted all of the recom-

mended tests in Step 2, Consult your Local Authorized Field Service Facility.
