(e) While holding the grip faces in position, attach all
four springs to the pins on the grip faces. Push the
grip faces into position until they are seated in the
track, if necessary, after attaching the springs.
(f) Rotate the actuating thumbwheel thoughout its range
to make sure the grip faces are opening and closing
properly.
Loading Specimens
To load specimens into the grips, do the following:
(a) Open the upper grip, using the actuating
thumbwheel, far enough to acommodate the thick-
ness (or diameter) of the specimen.
(b) While holding the specimen centered in the grip, ro-
tate the thumbwheel to close the grip. Tighten the
thumbwheel only enough to keep the specimen from
falling out.
(c) Open the lower grip using its thumbwheel.
(d) Center the specimen in the lower grip (if the upper
grip is not closed too tight, there will be some free-
dom of movement of the specimen).
(e) Close the lower grip by tightening its thumbwheel.
(f) Check the specimen alignment (it should be centered
in the grips and in line with the longitudinal axis of
the grips). Adjust the specimen position if necessary.
(g) Tighten both grips firmly by holding the grip with
one hand while turning the thumbwheel with the
other. The grips should be tightened enough to pro-
vide firm gripping pressure on the specimen, but
