PREPARATION FOR OPERATION.
as follows:
a. Check the gear case oil level (level with the oil level indi-
cator (11, fig 3-1) on the test stand side panel). If necessary, fill
the gear case with lubricant to that level.
b. Remove equipment that has been placed in the rectifier chamber
c. Check the readings of all seven instrument panel meters (M1
thru M7, fig 2-1). All meters should indicate 0. Zero adjust the
meter pointers, if necessary, by turning the adjustment screw located
at the center of the meter directly below the glass. Turning the
adjustment screw clockwise moves the pointer to the right, and turning
the adjustment screw counterclockwise moves the pointer to the left.
CAUTION
Do not overadjust the meter pointers. Damage may
result if this precaution is not observed.
d. When testing a voltage regulator in conjunction with a genera-
tor, be sure that the unit is properly and securely mounted on the
test stand (fig 2-6).
e. Use only the proper adapters, mounting flange adapter, cables,
and pulleys that are included in test stand accessories (fig 2-7), to
perform a test.
f. Before mounting generators or starters on the test stand, make
sure that the varidrive output shafts (1, 3, fig 1-2) are not ro-
tating.
g. Check all controls to make sure that they are set to the posi-
tions specified in table 2-1. Give special attention to BATTERY
CIRCUIT SELECTOR switch (S6, fig 2-2).
