8. Replacing Labels
Replace any missing, damaged or obscure labels. Replacement
labels are available from Federal Pacific.
9. Lubrication of Non-Current Carrying Parts
a. Non-current carrying parts, such as operating mechanism, hinges
and latches, may be lubricated with any lubricants that the user
has determined to be suitable for such applications.
b. Door latches on units with a date of manufacture prior to March
2008 should be regularly lubricated to prevent corrosion that
may render the latches inoperable. If latches become non-func-
tional and the door does not release, refer to Instruction Bulletin
IB-9D-810 (previously IB-1H-810).
10. Lubrication of Current Carrying Parts
When maintenance is performed, check for lubrication at the follow-
ing locations:
Lubrication is NOT required on any other current carrying sur-
faces than the locations identified. Applying lubrication in other
areas may reduce mechanical and electrical performance.
DO
NOT OVER LUBRICATE!
