2. DESCRIPTION
The tool frame (Figure 1) features two jaws, a handle, a ratchet adjustment wheel, and an emergency ratchet
release. Each die set consists of a crimper (upper die) and an anvil (lower die). The tool frame holds a die
assembly with three crimping chambers. Die-retaining screws are used to secure the dies in the tool frame.
The tool features a ratchet and an adjustment wheel with a range of settings. The ratchet ensures that the tool
has completed the cycle and does not release until the handles have been fully closed, unless the emergency
ratchet release is pressed to manually release the ratchet. The adjustment wheel controls the amount of handle
pressure exerted on the dies during the crimping procedure.
CAUTION
The dies bottom before the ratchet releases. This feature ensures maximum tensile performance of the crimp.

3. INSTALLING THE DIE ASSEMBLY
1. Open the tool handles and remove the two die-retaining screws from the tool jaws (see Figure 1).
2. Place the upper die in the stationary jaw of the tool frame so that the largest indenter is facing inward.
3. Insert a die-retaining screw through the stationary jaw and through the die. Tighten the screw just
enough to hold the die in place. Do not tighten the screw completely.
4. Place the lower die in the moving jaw of the tool frame so that the largest anvil is facing inward.
5. Insert a die-retaining screw through the moving jaw and through the die. Tighten the screw just enough
to hold the die in place. Do not tighten the screw completely.
6. Carefully close the tool handles, making sure the anvil and crimper align properly. Continue closing the
tool handles until the ratchet in the tool frame engages sufficiently to hold the dies in place.
7. Tighten both die-retaining screws.
4. REMOVING THE DIE ASSEMBLY
1. Open the tool handles until the ratchet releases.
2. Remove the two die-retaining screws.
3. Slide the dies out of the tool jaws.
5. CRIMPING
NOTE
The tool is provided with a crimp adjustment feature. Refer to section 7, INSPECTING THE CRIMP HEIGHT, and section 8,
ADJUSTING THE RATCHET, to verify crimp height before using the tool.
NOTE
The crimping chamber marked 12-10 cannot be used to crimp spade-type terminals.
1. Refer to Table 1 and select wire of the specified size and insulation diameter.
2. Strip the wire to the length indicated. Do not nick or cut wire strands.
3. Select an applicable terminal or splice and identify the appropriate crimp section according to the wire
size markings on the dies.
4. Hold the tool so that the back (wire side) is facing you. (See Figure 2.) Squeeze the tool handles
together until the ratchet releases and allow them to open fully.

5. Center the terminal or splice wire barrel on the anvil of the upper die as shown in Figure 3, Figure 4,
and Figure 5. If the brazed seam on the terminal or splice is visible, orient it toward the indenter.

6. While holding the wire barrel in place, squeeze the tool handles together until the ratchet engages
sufficiently to hold the terminal or splice in position. Do not deform the insulation barrel or wire barrel.
7. Insert the stripped wire into the wire barrel, making sure that the insulation does not enter the wire
barrel. See Figure 3.
8. While holding the wire in place, fully cycle the tool until the ratchet releases and allows the handle to
open.
9. To crimp the other half of a splice, reposition the uncrimped wire barrel in the crimping chamber and
repeat steps 1-8.
NOTE
If the splice cannot be turned for crimping the other half, turn the tool around.
10. Inspect the crimped terminal or splice as described in section 6.
11. Check the crimp height as described in section 7. If necessary, adjust the ratchet as described in
section 8.
CAUTION
Do not use damaged terminals or splices. If a damaged terminal or splice is evident, replace it with a new one.

6. INSPECTING THE CRIMP
Inspect crimped terminals and splices by checking the features shown in Figure 6. Poor crimps (Figure 7) can
be avoided by carefully following the procedures provided in section 5, and by following the tool maintenance
procedures provided in section 9.

Wire is visible through inspection hole. Wire is flush with or extends
slightly beyond end of wire barrel.

Wire size matches wire range or size stamped under tongue.

7. INSPECTING THE CRIMP HEIGHT
This inspection requires the use of plug gages conforming to the dimensions provided in Figure 8 and Table 2.
TE Connectivity does not manufacture or market these gages.

To gage the crimping chamber, complete the following steps:
1. Remove traces of oil or dirt from the crimping chamber and plug gages.
2. Close the tool handles until the crimping dies have bottomed. Do not force dies beyond initial contact.
3. Align the GO element with the crimping chamber. Gently push the element straight into the crimping
chamber. The GO element must pass completely through the crimping chamber (Figure 9).

4. Align the NO GO element and try to insert it straight into the same crimping chamber. The NO GO
element can start entry, but it must not pass completely through the crimping chamber (Figure 10).
Figure 10: NO GO element
If the crimping chamber conforms to the gage inspection, the tool is considered dimensionally correct.
Lubricate it with a thin coat of any good SAE 20 motor oil.
If not, return the tool to TE for further evaluation and repair. Refer to section 10, REPLACEMENT AND
REPAIR.
For additional information regarding the use of a plug gage, refer to instruction sheet 408-7424.

8. ADJUSTING THE RATCHET
The ratchet is preset prior to shipment, but it is important to verify the crimp height using a micrometer or
caliper. Use and wear can cause the tool to go out of adjustment. Inspect the crimp height and adjust the
ratchet, if necessary, on a regular basis.
To adjust the ratchet, complete the following steps.
1. Remove the lock screw from the ratchet adjustment wheel (Figure 11).
2. With a screwdriver, adjust the ratchet wheel from the front side of the tool.
If the crimp height is larger than recommended, rotate the adjustment wheel counter-clockwise ()
to a higher setting.
If the crimp height is smaller than recommended, rotate the adjustment wheel clockwise (–) to a
lower setting.
3. Reinstall the lock screw.
4. Make a sample crimp and measure the crimp height.
5. Repeat as required.
If the crimp height cannot be made to conform to the recommended crimp height, replace the tool or die
set. See section 10, REPLACEMENT AND REPAIR.

9. MAINTENANCE AND INSPECTION
9.1. Maintenance
Remove dust, moisture, and other contaminants with a clean, soft brush or soft, lint-free cloth. Do not
use objects that could damage the dies or tool.
When the tool is not in use, keep the handles closed to prevent objects from becoming lodged in the
dies.
Remove all lubrication and accumulated film by immersing the dies in a suitable commercial degreaser.
Store the tool in a clean, dry area.
9.2. Visual inspection
Inspect the tool and dies on a regular basis to ensure that they are not worn or damaged.
Inspect the crimping chambers of the die assembly for flattened, chipped, worn, or broken areas.
If damage or abnormal wear is evident, replace the tool or dies. Refer to section 10, REPLACEMENT
AND REPAIR.
