MAINTENANCE INSTRUCTIONS
58. Genera Z. - Mechanisms of the class of the sight assemblies,
comprising principally an elaborate system of mechanical
signal transmission, require high mechanical accuracy
and must have exacting care. Accurate transmission of input
movements has been attained by design arrangements and exceedingly
high standards of manufacture. If the units are maintained
in alignment, are periodically checked for accuracy and
are lubricated and ot'herwise serviced as prescribed, they will
retain their design features.
59. Lubri c at i on, - All points of shaft support, all gear
brackets, gearing and all moving elements of signal.transmission
and telescope mounting have been provided with means for lubrication.
In many instances correct lubrication will only be
obtained provided the lubricants prescribed on the· charts are
used. This is particularly important with respecrt to the in-
·ternal mechanisms of the housings at t.r-a.LnerI s sand pointer I s
stations, - oil is required at certain fittings, grease must
not be substituted. Lubricants should be applied sparingly
but regularly.
60. Disassemb.Zy and- assembly. - Disassembly and reassemb.Lyofall
units of the sight, optical instruments, attached
indica tors and transmitters excepted, are, appar-ent. from the
drawings. All such work should be performed by experienced
personnel only, with' the special tools provided and only after
mating parts are marked at. couplings, gears, etc., to provide
for correct reassembly.
Equipment attached to the sight assemblies may be
dismantled only by authorized personnel familiar with such
optical and fire control instruments.
