Step 1. LOCATE PROBLEM (SYMPTOM).
Look under the column labeled “ PROBLEM

sible symptoms that the machine may
exhibit. Find the listing that best describes

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

mended tests in Step 2, Consult your Local
