Make sure that matched die set, terminal, and wire
size are compatible. With crimping head properly
installed, refer to die set instructions, and
insert/change die set as follows:
1. Remove latch pin and open yoke on crimping
head.
2. Loosen setscrew in yoke. Refer to die set
instructions and insert stationary (upper) die which
includes the nest area into well of yoke. Tighten
setscrew.
3. Activate power unit to advance ram until
setscrew is visible (about 12.7 mm [.50 in.]).
Loosen setscrew.
4. Insert moving (lower) die, which serves as the
indenter, into ram well, making sure that moving
die is properly oriented to mate with stationary die.
Tighten setscrew.
5. Close yoke and secure with latch pin.
6. Slowly close dies to ensure proper alignment.
7. Complete the cycle and return the ram to the
DOWN position.
CAUTION
!
Always ensure that latch pin is fully inserted or
damage may occur to yoke, dies, or latch pin.
Figure 2
The following crimping procedure provides general
information. Refer to instructions packaged with
individual die sets for specific products, wire sizes,
strip dimensions, positioning of terminals and splices
in the dies, and crimping procedures.
CAUTION
!
Never operate the power unit without having a
crimping head attached to the hose.
1. Insert terminal or splice in the stationary (upper)
die according to instructions packaged with the
dies. Make sure the latch pin is secure before
activating the power unit.
2. Slowly advance moving (lower) die with short,
quick strokes until terminal or splice is secure.
3. Insert the stripped wire.
4. Cycle tool to complete crimp. Remove crimped
terminal or splice.
NOTE
i
If the splice or terminal sticks in the die after
crimping, apply a rocking action to remove it from
the die.
5. CRIMPING PROCEDURE
DANGER
