8. Generously apply the NO-OX-ID compound (enough to cover
with a noticeable film) to the cleaned inside movable contact
blades and the cleaned sides of the stationary contacts. Also
apply the compound to the hinge area (between the blades and
the stationary hinge). Work the compound into the hinge point
by rotating the contact blades several times. Do not loosen or
disassemble any of the large brass contact blade nuts. Do not
readjust these nuts or loosen the small Allen head set screw.
Refer to Figure 7.
9. Lubricate the BPS Linkages (they operate the bolts on the
Movable Blades) with light machine oil. Do not mix the light
machine oil with the previously applied NO-OX-ID compound.
Do not apply the light machine over the previously applied
NO-OX-ID compound.
10. Refer to Figure 6. Return the contact blades to their original
operating positions by rotating the contact blades (reverse the
procedure in step 6 of this section). An audible click will be
heard when the contacts have been returned to their original
positions.
11. Re-install the BPS clear cover with the eight cover screws that
were removed in step 5 of this section.
ATTENTION
The brass contact nuts are factory adjusted and must
not be loosened or tampered with. If the brass nut is
tampered with, the switch can malfunction and cause
these nuts to be out of adjustment.
