formance and possible overheating.

thoroughly so that the element is evenly
permeated with the oil.
c. Wrap the element in a clean cloth, rub the
element gently, and wipe off any excess
oil.
TIP
•
The element should be permeated with oil so
that it is wet but not dripping.

When replacing the element, permeate the el-
ement in oil by using the same procedure as
when cleaning.
