TO REMOUNT THE BASE
JAWS:
a. Rotate the scroll until you
can see the thread start at loca-
tion 1.
b. Back the scroll up until the
start of the thread just disap-
pears, and slide the No. 1 base
jaw into the slot.
c. While pushing inward on the
No. 1 base jaw, rotate the scroll
90Þ. Pull outward on the No. 1
base jaw to make sure that it has
engaged properly with the
scroll. If the jaw comes out, start
the process again.

5. After removing the snap ring, turn the chuck upside down into your hand
and the scroll should fall straight out. The STRONGHOLD is manufactured
with very tight tolerances, and sometimes a little jiggling is necessary to get
the scroll out. Note: Do not use a wire brush on the scroll. This can damage
the lubricating properties on the surfaces.

To clean your chuck, simply brush clean. If it is sticky, soak in varsol or
mineral spirits with about 10% oil added. Allow to sit for 1/2 hour or more,
and blow clean.
TO DISASSEMBLE YOUR STRONGHOLD
:
1.
Remove Top Jaws
. You may want to remove the Top Jaws either for
cleaning purposes, or to exchange them for an optional set of jaws for a pro-
ject which requires Jaws with a different capacity. To remove the Top Jaws,
use the 4mm T-Handle hex key and unscrew the eight screws counterclock-
wise. The jaws are pulled in on a taper, so after the screws are out, it is usu-
ally necessary to give them a tap (with the T-handle of the hex key) to knock
them loose from the taper. It is possible to disassemble the chuck and leave
three of the Top Jaws on - just locate the Top Jaw with the pin, and remove
it.
2.
Remove Base Jaws
. To remove the base jaws, you must remove at least
one of the Top Jaws. All four Top Jaws can be removed, but for cleaning
purposes, it is usually only necessary to remove one - that being the one
with the pin (this may be base jaw No 2 or No 4 depending on if it is located
in the short or long slot respectively). After this Top Jaw is off, use the key
and open the chuck until the jaws stop moving. When the jaws are no longer
moving, they are loose from the scroll and can be slid from the slots out of
the body.
3.
Remove the adaptor
(refer to above page 8). It is necessary to remove
the adaptor in order to remove the snap ring.
4.
Remove the snap ring
