3. CRIMPING PROCEDURE
Strip the wire to the length indicated, taking care not
to cut the wire strands. Select an applicable contact
and identify the appropriate crimping chamber
according to the wire size markings on the tool.
NOTE: Use 24-28 crimp section for 24-28 AWG
wire. Use 20-24 crimp section for 20-22 AWG wire.
Refer to Figure 2, and proceed as follows:
1. Hold the tool so that the front is facing you.
Squeeze tool handles together and allow
them to open fully.
2. Insert the contact (mating end first) into the
hole in the locator which corresponds with
the appropriate crimping chamber. Make
sure that the open “U” of the wire barrel and
insulation barrel face up towards numerical
markings on tool.
CAUTION Make sure that both sides of the
contact insulation barrel are started
evenly into the crimping chamber.
Do NOT attempt to crimp an
improperly positioned contact.
3. Hold the contact in position, and squeeze
the tool handles together until ratchet
engages sufficiently to hold the contact in
position. Do NOT deform insulation barrel
or wire barrel.
3. Insert stripped wire into contact insulation
and wire barrels until wire and insulation are
visible in inspection window, as shown in
Figure 2.
5. Holding the wire in place, squeeze the tool
handles together until ratchet releases.
Allow tool handles to open and remove
crimped contact.
