To
adjust, proceed as follows:
If there is no clearance between the
armature locking wedge
and
the No.
1
sword, loosen the lock nut on the upper
pivot screw
and
adjust to obtain clearance, noting that a quarter-turn of the
screw is equivalent to approximately
.006".
Remove the armature bracket
and
adjust the lower pivot screw
to
obtain the proper armature end plq. Replace
the armature bracket.
If there is .roore than
•
008"
clearance, remove the armature bracket
and
adjust the lower pivot screw. Replace the bracket an d adjust the armature
end pla;y
by
means of the upper pivot screw.

The position of the armature bracket should be such that a line
through the center of the No.
1
sword extends approximatezy through the centers
of the armature pivot screws when the swords
are
held midwtcy" between the stop
posts by means of the No.

gauge pins.
To adjust, proceed as follows:
(1)
Remove the range finder; unhook the locking lever spring; loosen the
magnet bracket mounting screws, and move the bracket to its rearmost
position. Loosen the armature bracket mounting screws, the link
screw,
a.nd
back off the armature stops. Move the bracket eccentric
out of the
way
so that it will not interfere with t.he adjustment.
Rotate the main shaft until the No.
1
selector lever rests on the
peak of its cam.
l2)
Hold the swords in
a.
position midway between the two stop posts by
means of the gauge pins inserted betwee.n the stop posts and the
swords. Be sure that both the armature extension arms are betw een
the arms of the swords. With the swords held in this position, place
the No.

locating gauge over the end of the No.
1
sword,
so
that
the two legs of the gauge are against the ends of the sword arms.
Move the bracket to a position where both armature extension arms
are
against the flat surface between the legs of the gauge.
(3) Hold the bracket in this position and tighten the
link
screw on]¥.
Renove the locating gauge and the two gauge pins.

(Figure 33)
The position of the
arma
ture bracket should be such as to provide
some
clearance, not more than
.040",
between each sword
and
either stop
post
under the following conditions:
Rotate the
main
shatt until the No. l s elector lever is
resting
on
the peak
of
its cam. With the armature in its unoperated (SPACING)
position,
move the spacing arm of the No. l sword against the
armature
extension.
Place a
.040"
wire gauge against the spacing stop post
and
rotate the
armature slowly' toward the !lARKING position. The blade of the
SWQrd
should
strike the
.040"
gauge before the armature leaves the spacing
arm
of the sword.
Under these conditions, the a rmature will move the sword to not mre than
.040"
of the stop post. Remove the
.04011
gauge and repeat the above procedure. The
arma
ture should leave the spacing arm of the sword before the blade
of
the
