1. INTRODUCTION
Double Action Hand Tool (DAHT) 1804834--1 and
Crimping Head 1--1804834--1 (shown in Figure 1) are
used to crimp Raychem MiniSeal Splices listed in
Figure 2 onto stranded wire sizes 26--12 AWG.
Read these instructions thoroughly before using the
tool.
NOTE
Dimensions in this instruction sheet are in
millimeters [with inch equivalents in brackets].

3. CRIMPING PROCEDURE
Strip the wire according to the dimensions listed in
Figure 2. The strip length is determined by the splice
and by the wire size. Do not nick or cut the wire
strands. Proceed as follows:
1. Close the tool handles until the ratchet releases.
Allow the tool handles to open fully.
2. Place the splice against the locator in the
appropriate crimp chamber. See Figure 3.
3. While holding the splice in place, squeeze the
tool handles together just until the jaws begin to
close on the wire barrel. Do NOT deform the wire
barrel.
4. Insert the stripped wire into the wire barrel,
making sure that the wire insulation does not enter
the wire barrel.
5. While holding the wire in place, squeeze the tool
handles together until the ratchet releases, then
allow the tool handles to open fully.

2. DESCRIPTION
The tool consists of a ratchet, two crimping jaws
(indenter and anvil) containing three crimping
chambers, and a terminal locator. The tool is marked
with the wire size range for each crimping chamber.
See Figure 1. Full crimping of the splice is assured by
the ratchet. Once engaged, the ratchet does not

5. MAINTENANCE AND INSPECTION
Tyco Electronics recommends that a maintenance
and inspection program be performed periodically to
ensure dependable and uniform terminations.
Frequency of inspection depends on:
1. The care, amount of use, and handling of the
hand tool.
2. The presence of abnormal amounts of dust and
dirt.
3. The degree of operator skill.
4. Your own established standards.
The tool is inspected before being shipped; however,
Tyco Electronics recommends that the tool be
inspected immediately upon arrival at your facility to
ensure that the tool has not been damaged during
shipment.

5.1. Daily Maintenance
1. Remove dust, moisture, and other contaminants
with a clean brush, or a soft, lint--free cloth. Do
NOT use objects that could damage the tool.
2. Make certain that the retaining pins are in place
and that they are secured with retaining rings.
3. All pins, pivot points, and bearing surfaces
should be protected with a thin coat of any good
SAE 20 motor oil. Do NOT oil excessively.
4. When the tool is not in use, keep handles closed
to prevent objects from becoming lodged in the
crimping jaws. Store the tool in a clean, dry area.
If the wire is stripped correctly (Figure 2), the
conductor will be exposed slightly more than the
thickness of the locator. This will allow the
conductor to enter the slot in the locator
Figure 3
6. To crimp the other half of a butt splice, position
the crimped wire barrel against the locator. The
crimped wire will go through the slot in the locator.
The uncrimped barrel will line up with the crimping
chamber. Repeat the crimping procedure.
NOTE
If the splice cannot be turned for crimping other
half, turn the tool around.
5.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Tools used in daily production—lubricate daily
Tools used daily (occasional)—lubricate weekly
Tools used weekly—lubricate monthly
i
4. CRIMP INSPECTION
Inspect crimped terminals and splices by checking the
features described in Figure 4. Poor crimps can be
avoided by carefully following the procedures
provided in Section 3, and by following the tool
maintenance procedures provided in Section 5.
5.3. Periodic Inspection
1. The tool should be immersed (handles partially
closed) in a reliable commercial degreasing
compound to remove accumulated dirt, grease,
and foreign matter.

then allow them to open freely. If they do not open
quickly and fully, the spring is defective and must

3. Inspect head assembly for worn, cracked, or
broken jaws. Refer to Figure 5. If damage is
evident, return the tool to Tyco Electronics for
evaluation and repair. See Section 6,
REPLACEMENT AND REPAIR.
5.4. Gaging the Crimping Chambers
This inspection requires the use of a plug gage
conforming to the dimensions provided in Figure 6.
Tyco Electronics does not manufacture or market
these gages. To gage the crimping chambers,
proceed as follows:
1. Remove traces of oil or dirt from the crimping
chambers and plug gage.
2. Close the tool handles until it is evident that the
jaws have bottomed; then hold in this position. Do
NOT force the jaws beyond initial contact.

1. Select a terminal or splice, and properly stripped
wire with

wire load (such as wire size 16
AWG and size 22--16 terminal).
2. Position the terminal or splice and wire between
the crimping jaws, as described in Section 3.
3. Hold the wire in place and squeeze the handles
until the CERTI--CRIMP ratchet releases. Hold the
handles in this position, maintaining just enough
tension to keep the jaws closed.
4. Check the clearance between the bottoming
surfaces of the crimping jaws. If the clearance is
0.025 [.001] or less, the ratchet is satisfactory. If
clearance exceeds 0.025 [.001], the ratchet is out
of adjustment and must be repaired. See Section
6, REPLACEMENT AND REPAIR.

If the crimping chambers conforms to the gage
inspection, the tool is considered dimensionally
correct, and should be lubricated with a THIN coat of

returned for further evaluation and repair. Refer to
Section 6, REPLACEMENT AND REPAIR.
5.5. CERTI- CRIMP Ratchet Inspection
