TO CHECK LEVEL BUBBLES ON CHARTS: First, adjust
chart feet screws for plumbing the chart faces, as
explained in Section B, Page 3. Slide the charts back
and forth to make sure the rollers are properly posi-
tioned on top frame rails. Adjust charts by using
adjusting handles so that the vertical red toe lines are
plumb, using a good carpenter level, plumb-bob, or
even a bolt tied to a string. (See Figure 11.) Then check
level bubbles for accuracy. If the bubbles are not
exactly centered, loosen the screws holding the level
barrels and adjust properly. Hence, when the level
bubble is centered, the vertical red toe line is exactly
vertical.
These levels are carefully adjusted at the factory;
however, for precision wheel alignment, we suggest
rechecking for possible change during shipment.
The calibration of the charts is no more accurate
than the leveling, as they are based on a level
reference.

2. TO CHECK REAR TOE GAGE (Supplied as an accessory):
Use a carpenter square to check the squareness of the
flags with the toe gage channel. (See Figure 12). It
may be necessary to straighten or shim the flags if
they are bent. `
TO CHECK PROJECTOR ADAPTOR ASSEMBLY: First
place projector on the floor or rack and slide center
casting of projector (See Figure 13) on rods to approxi-
mate center between top and bottom casting. Check
FIGURE 12
for play between center casting and rods, by feeling
with your fingers while moving projector head up
and down (Do not mistake compensator springs flexing
for looseness). Check the four pressure pins and screws
on center casting and on top casting for enough snug-
ness so that they slide very firmly along the rods when
pushed with your thumbs. Check tightness of all screws
that hold rods and rim buttons.
