Problems and Solutions

Error indicators ................page 3-4
Operating problems ........page 3-5
Quality problems .............page 3-7
See the table in “Error indicators” first, and if the information
there does not help you solve the problem, go to the category
for the type of problem you have and look for the description
that most closely matches the problem.
