WARNING
Before servicing the switch, be sure it is
disconnected from all electric power
sources and properly grounded.
A certain amount of care and inspection is
recommended. The frequency of inspection
depends upon atmospheric conditions and
frequency of operation. The service interval is
largely determined by the user. Recommended
maintenance is similar to that listed in the latest
industry standards.
First, it is important that the
insulators are always clean. It is also important

ANSI C37.35 (American National Standard Guide
for the Application, Installation, Operation and
that the contacts be examined to see that they are
aligned, clean, and have a firm uniform pressure.
If the contacts are pitted, or burned to some
extent, they should be removed and replaced.
Under normal service conditions, the jaw
contacts should be examined and maintained at
least once a year, depending upon the type of
atmosphere to which they are exposed.
Periodic maintenance should consist of cleaning
the contact surfaces thoroughly by carefully
scraping off any contamination or deposit and
sanding the surface entirely clean, a coating of
lubricant should be applied. Suggested
lubricants are MOBIL 28 grease of NO-OX-ID
