SECTION 7: MAINTENANCE AND
COMPONENT REPLACEMENT
7.1 Introduction
In general, ATS equipment is designed to be relatively mainte-
nance free under normal usage. However, because of the variabil-
ity of application conditions and the importance placed on
dependable operation by this type of equipment, inspection and
maintenance checks should be made on a regularly scheduled
basis. Since equipment maintenance will consist mainly of keep-
ing the equipment clean, the frequency of maintenance will
depend, to a large extent, on the cleanliness of its surroundings.
If a significant amount of dust or foreign matter is present, a more
frequent maintenance schedule should be followed.
It is suggested that visual inspections of the equipment be made
on a regular basis, not just during regularly scheduled periods.
Always be alert for an accumulation of dirt in and around the
structure, loose parts and/or hardware, cracks and/or discolora-
tion to insulation, and damaged or discolored components.
