5. Insert stationary die (with large shank) into
yoke as shown in Figure 2. Tighten setscrew.
6. Activate tool to advance ram until setscrew is
visible.
7. Loosen setscrew in ram and insert moving die
(with small shank) into ram well as shown in
Figure 2. Tighten setscrew.
NOTE
i
Moving die must be properly oriented to mate with
stationary die.
8. Tighten socket head cap screws holding
insulation crimp section of dies.
9. Activate power unit to allow ram to return to the
“down” position
2.2. Die Removal
1. Remove latch pin and open yoke.
2. Loosen setscrew in yoke and remove
stationary die.
3. Raise ram to “full up” position. Loosen
setscrew and remove moving die.
3. OPERATION
3.1. Wire Stripping and Crimping Procedure
DANGER
STOP
Avoid personal injury. When operating power unit,
exercise caution while holding terminals or wire
near crimping area. Never place anything in the
dies except TE Connectivity Terminals.
1. Strip wire to dimensions listed in Figure 1. Do
NOT nick or cut conductor strands.
2. Insert stripped wire in terminal. End of wire
must be flush with or extend beyond edge of
terminal wire barrel.
3. With yoke open, place terminal on dies. See
Figure 3, Detail A. Bottom of terminal tongue
should face stationary die and terminal wire
barrel should rest against spring-loaded locator.
NOTE
i
When crimping pre-insulated AMPOWER terminals
in die 48755-1, it will be necessary to remove the
locator. Position the terminal in dies as shown in
Figure 3, Detail B. Bottom of terminal tongue faces
stationary die and rear of terminal tongue butts
against the side of the die.
4. Close yoke and insert latch pin.
CAUTION
Ensure that latch pin is fully inserted or damage may
occur to yoke, dies, or latch pin.
!
5. Hold terminal in place and activate power unit
to complete the crimp. Open yoke and remove
crimped terminal.
NOTE
i
If terminal sticks in die after crimping, apply a
rocking motion to remove the die.
3.2. Insulation Crimp Adjustment
This adjustment is made to both stationary and
moving dies after they have been placed in crimping
head.
NOTE
i
Crimping Dies 48752-1, 48754-1, and 48755-1
have four socket head cap screws and two pin-
keys for insulation crimp adjustment. Crimping Die
48753-1 has two socket head screws and four pin-
keys for adjustments.
1. The dies have three insulation crimp positions.
The adjustment is made by moving a pin-key
(see Figure 1). When the pin-key is pushed all the
way in, the insulation crimping section of the die
is in the loose position; when the pin-key is
halfway out, the insulation crimping section of the
die is in the medium position; when the pin-key is
all the way out, the insulation crimping section of
the die is in the tight position.
2. To adjust the insulation crimp, loosen socket
head cap screws and push pin-key all the way in
so that insulation crimp section of the die is in the
loose position.
3. Press and hold insulation die down against the
pin-key. This will prevent the spring-loaded pin-
key from popping back.
4. Tighten socket head cap screws.
NOTE
i
Make certain insulation crimping sections of
moving and stationary dies are both adjusted to the
same position.
