PROPER USE GUIDELINES

Cumulative trauma disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional

use and low-volume applications. A wide selection of powered application equipment is available for extended-use production operations.

2. DESCRIPTION

Each tool consists of a CERTI-CRIMP tool ratchet and two crimping jaws (indenter and anvil) containing one,

two, or three crimping chambers. Each tool is marked with the wire size range for each crimping chamber

(Figure 1). Full crimping of the terminal or splice is assured by the CERTI-CRIMP tool ratchet. When engaged,

the ratchet does not release until the tool handles have been fully closed.

CAUTION

The crimping jaws bottom before the ratchet releases. This feature ensures maximum electrical and tensile performance of

the crimp. Do not re-adjust the ratchet.

3. CRIMPING

1. Strip the wire according to the dimensions listed in Table 1. The strip length is determined by the type

of terminal or splice and by the wire size. Do not nick or cut the wire strands.

2. Close the tool handles until the ratchet releases.

3. Allow the tool handles to open fully.

4. Center the terminal or splice wire barrel in the appropriate crimping chamber (Figure 2).

For terminals, make sure that the flat side of the tongue faces the anvil or the nest.

For splices, make sure that the brazed seam (when visible) is toward the indenter or the nest.

NOTE

Terminals and splices can also be rotated 180 degrees with the seam toward the nest.

5. While holding the terminal or 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.

6. Insert the stripped wire into the wire barrel, making sure that the wire insulation does not enter the wire

barrel (Figure 3).

8. To crimp the other half of a butt splice, position the uncrimped wire barrel in the crimping chamber and

repeat the crimping procedure.

NOTE

If the splice cannot be turned for crimping the other half, turn the tool around.

4. INSPECTING THE CRIMP

Inspect crimped terminals and splices by checking the features shown in Figure 4. Poor crimps (Figure 5) can

be avoided by carefully following the procedures provided in Section 3, and by following the tool maintenance

procedures provided in Section 5.

Crimp is centered. Crimp can be off center, but not off end of wire barrel.

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.

Bare wire ends are flush with or extend slightly beyond end of wire barrel.

Wire size matches wire range or size stamped on splice.

5. MAINTENANCE AND INSPECTION

The tool is inspected before being shipped. Inspect it immediately upon arrival at your facility to ensure that the

tool has not been damaged during shipment.

Frequency of inspection depends on:

The care, amount of use, and handling of the hand tool

The presence of abnormal amounts of dust and dirt

The degree of operator skill

Your own established standards

5.1. Daily 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.

Make certain that the retaining pins are in place and that they are secured with retaining rings.

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.

When the tool is not in use, keep the handles closed to prevent objects from becoming lodged in the

dies. Store the tool in a clean, dry area.

5.2. Lubrication

Lubricate all pins, pivot points, and bearing surfaces with SAE 20 motor oil as indicated in Table 2.

NOTE

Wipe excess oil from the tool, particularly from the crimping area. Oil transferred from the crimping area onto certain

terminations can affect the electrical characteristics of an application.

5.3. Periodic inspection

Remove accumulated dirt, grease, and foreign matter by immersing the tool (with handles partially

closed) in a reliable commercial degreasing compound.

Close the tool handles until the ratchet releases and then allow them to open freely. If they do not open

quickly and fully, the spring is defective and must be replaced. See Section 6, REPLACEMENT AND

REPAIR.

Inspect the head assembly for worn, cracked, or broken jaws (Figure 6). If damage is evident, return

the tool to TE for evaluation and repair. See Section 6, REPLACEMENT AND REPAIR.

TE 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.

3. Align the GO element with the crimping chamber. Push element straight into the crimping chamber

without using force. The GO element must pass completely through the crimping chamber (Figure 8).

4. Align the NO-GO element and try to insert it straight into the same crimping chamber. The NO-GO

element can enter partially, but must not pass completely through the crimping chamber (Figure 8).

NOTE

The jaws in Tools 49935 and 574573 are not symmetrically located. Make sure that the tool conforms to the symmetry

requirements shown in Figure 9.

Jaws

0.254 mm [.010 in.] minimum (typical)

If the crimping chambers conform 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, the tool must be returned for further evaluation and repair. Refer to Section 6, REPLACEMENT

AND REPAIR.

For additional information regarding the use of a plug gage, refer to Instruction Sheet 408-7424.

5.5. Inspecting the ratchet

1. Check the CERTI-CRIMP tool ratchet to verify that the ratchet does not release prematurely, allowing

the jaws to open before they have fully bottomed.

2. Obtain a 0.025 mm [.001 in.] shim suitable for checking the clearance between the bottoming surfaces

of the crimping jaws.

3. Select a terminal or splice, and properly stripped wire with maximum wire load (such as wire size 16

AWG and size 22-16 terminal).

4. Position the terminal or splice and wire between the crimping jaws, as described in Section 3,

CRIMPING.

5. Hold the wire in place and squeeze the handles until the CERTI-CRIMP tool ratchet releases. Hold the

handles in this position, maintaining just enough tension to keep the jaws closed.

6. Use the shim to check the clearance between the bottoming surfaces of the crimping jaws.

If the clearance is 0.025 mm [.001 in.] or less, the ratchet is satisfactory.

If clearance exceeds 0.025 mm [.001 in.], the ratchet is out of adjustment and must be repaired.

See Section 6, REPLACEMENT AND REPAIR.
