4. Perform a test crimp as described in Section 3, Step 6. Remove the crimped terminal or splice and

check the insulation support. Bend the wire back and forth once. The insulation barrel sleeve should

retain grip on the wire insulation. If the wire pulls out, move the insulation crimping adjustment pins to

the next tighter position (Position 2) and proceed to Step 5. If the wire does not pull out, the pins are

properly adjusted and the tool is ready for crimping.

5. Perform another test crimp as described in Step 4. Adjust pins, as necessary, until the desired

insulation grip is obtained. Do not use a tighter setting than is required.

NOTE

The insulation crimping adjustment pins must be located in the same adjustment position.

5. MAINTENANCE AND INSPECTION PROCEDURE

It is recommended that a maintenance and inspection program be performed periodically to ensure dependable

and uniform terminations. Frequency of inspection should be adjusted to suit your requirements through

experience and depends on:

The hand tool is inspected and calibrated before being shipped; however, it is recommended that the tool be

inspected immediately upon arrival to ensure that the tool has not been damaged during shipment.

5.1. Daily Maintenance

1. The hand tool should be immersed (handles partially closed) in a reliable commercial degreasing

compound to remove accumulated dirt, grease, and foreign matter. When degreasing compound is

not available, tool may be wiped clean with a soft lint-free cloth. Do NOT use hard or abrasive 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.

5.2. Lubrication

Lubricate all pins, pivot points, and bearing surfaces with SAE 20 motor oil as follows:

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

terminations may affect the electrical characteristics of an application.

5.3. Visual Inspection

1. Close tool handles until 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.

2. Inspect head assembly for worn, cracked, or broken jaws. If damage is evident, return the tool for

evaluation and repair. Refer to Section6, REPLACEMENT AND REPAIR.

5.4. Gaging the Crimping Chamber

This inspection requires the use of plug gages conforming to the dimensions provided in Figure 7. TE

Connectivity does not manufacture or market these gages.
