3. Inspect termination to ensure that insulation is
1.02 [.040] minimum beyond the front contact
beam.
4. If, upon inspection, it is determined that the wire
is not inserted deeply enough, increase the air
pressure by 69 kPa [10 psi], and repeat the
termination and inspection procedure. Continue in
this manner until either the proper insertion depth
is obtained or the air pressure is set to 483 kPa
[70 psi]. If the proper insertion depth is NOT
reached at 483 kPa [70 psi], return the air pressure
to 276 kPa [40 psi] and follow the procedure in
Paragraph 3.3, Wire Insertion Depth Adjustment.
5. If the wire is inserted too deeply, refer to the
procedure in Paragraph 3.3, Wire Insertion Depth
Adjustment.
3.3. Wire Insertion Depth Adjustment
Wire Too Deep in Contact Slot – If the wire is inserted
too deeply, remove the head, and turn the adjuster
1/6 revolution CLOCKWISE (see Figure 4). This will
reduce the wire insertion depth by approximately 0.20
[.008]. Repeat Steps 3, 4, and 5 of Paragraph 3.1, for
Pistol Grip Manual Handle Assembly.
Wire Not Deep Enough in Contact Slot – If the wire is
not inserted deeply enough in contact slot, remove
the head and turn the adjuster 1/6 revolution
COUNTERCLOCKWISE (see Figure 4). This will
increase the wire insertion depth by approximately
0.20 [.008]. Repeat Steps 3, 4, and 5 of Paragraph
3.1, (or Steps 3 and 4 of Paragraph 3.2).
4. TERMINATING PROCEDURE
(Figure 5)
1. Insert connector into left side of head as
indicated.
2. Align contact to be terminated with wire inserter.
3. Make sure locating pawl rests between
connector index ribs.
4. Insert an unstripped wire into the funnel area
between contact and wire inserter until it bottoms
on tool base.
5. Depress trigger (or squeeze cam handle) of
pistol grip handle assembly and hold it until inserter
bottoms or ratchet releases.
6. Release trigger (or cam handle). The inserter
will retract and the feed slide will automatically
advance connector to next contact position.
