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.

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