1. Close the tool handles until the ratchet releases,
then allow the handles to open FULLY.
2. Holding the contact by the mating end, insert the
contact, insulation barrel first, through the front of
the tool and into the appropriate crimping chamber.
3. Position the contact so that the open “U" of the
insulation barrel faces the top of the tool. Place the
contact up into the nest so that the movable locator
drops into the slot in the contact. Refer to Figure 3.
Butt the front end of the wire barrel against the
movable locator.
CAUTION
!
Make sure that both sides of the insulation barrel
are started evenly into the crimping chamber.
Do not attempt to crimp an improperly positioned
contact.
4. Hold the contact in position and squeeze the tool
handles together until ratchet engages sufficiently to
hold the contact in position. DO NOT deform the
insulation barrel or wire barrel.
5. Insert stripped wire into the contact insulation
barrel and wire barrel until it is butted against the
wire stop as shown in Figure 3.
6. Holding the wire in place, squeeze tool handles
together until the ratchet releases. Allow the tool
handles to open, and remove the crimped contact.
NOTE
i
The crimped contact may stick in the crimping area,
but can be easily removed by pushing downward
on the top of the locator (see Figure 3).
7. Inspect the crimp according to Section 6, CRIMP
HEIGHT INSPECTION.
CAUTION
!
DO NOT use defective or damaged contacts. Cut
the contact from the wire and use a new contact.
5. ADJUSTMENTS
5.1. Contact Support Adjustment
1. Make a sample crimp and determine if the contact
is straight, bending upward, or bending downward.
2. If the contact is bending upward or downward,
loosen the screw that holds the contact supports
onto the locator assembly. See Figure 3.
3. Place a contact with wire into the proper nest and
close the tool handles until the ratchet reaches the
sixth click or until the additional contact support
touches the contact.
NOTE
i
The ratchet has detents that create audible clicks
as the tool handles are closed.
4. Slightly loosen the nut that holds the locator
assembly onto the tool frame.
5. Move the contact support and secondary contact
support as required to meet the dimensions given in
Figure 3.
6. Tighten the nut, and close the handles until the
ratchet releases.
7. Remove and inspect the contact. Make another
sample crimp. If the contact is straight, tighten the
screw. If the contact is still being bent during
crimping, repeat the adjustment procedure.
5.2. Ratchet Adjustment
The tool ratchet mechanism features an adjustment
wheel with numbered settings. The adjustment wheel
controls the amount of handle pressure exerted on the
jaws during crimping. If the crimp is not acceptable,
adjust the ratchet as follows.
