TOW MissIle SIghts .±²
Keeping the day and night sights of
your TOW missile system Fnctional is
all in the way you handle them.
±or instance, if your day sight has
rails ²r mounting the night sight on top
of it, don't stack things on the rails
when the night sight is not mounted.
The rails can be burred, nicked and
damaged to the point where they won't
accept the night sight. That means
downtime f³r maintenance.
24
When you set the night sigh´ down
after removal or be²re installation, set
it on the side where the coolant car-
tridge is. That way you can prevent
parts damage, such as to the mount
latch handle. If you' re removing the
sight, stacking it on its side can prevent
damage till you get it in the field hanµ
dling case.
