Make sure that both sides of the insulation barrel

are started evenly into the crimping section. Do

NOT attempt to crimp an improperly positioned

contact.

4. Hold the contact in position and squeeze the

tool handles together until ratchet engages

sufficiently to hold the contact in position. Do NOT

deform insulation barrel or wire barrel.

5. Insert stripped wire into contact insulation and

wire barrels until it is butted against the wire stop,

as shown in Figure 3.

6. Holding the wire in place, squeeze tool handles

together until ratchet releases. Allow tool handles

to open and remove crimped contact.

The crimped contact may stick in the crimping

area, but the contact can be easily removed by

pushing downward on the top of the locator (see

Figure 3).

7. Check the contact’s crimp height as described in

Section 6, CRIMP HEIGHT INSPECTION. If

necessary, adjust the crimp height as described in

Section 7, CRIMP HEIGHT ADJUSTMENT.

Damaged contacts may not be used. If a

damaged contact is evident, it must be cut from

the wire and replaced with a new one.

6. CRIMP HEIGHT INSPECTION

This inspection requires the use of a micrometer with

a modified anvil. Tyco Electronics does not

manuafacture or market these gages, however TE

recommends a modified micrometer (Crimp Height

Comparator RS–1019–5LP).

Proceed as follows:

1. Refer to Figure 4 and select a wire (maximum

size) for each crimp section listed.

2. Refer to Section 5, CRIMPING PROCEDURE,

and crimp the contact(s) accordingly.

3. Using a crimp height comparator, measure the

wire barrel crimp height as shown in Figure 4. If the

crimp height conforms to that shown in the table,

the tool is considered dimensionally correct. If not,

the tool must be adjusted. Refer to Section 7,

CRIMP HEIGHT ADJUSTMENT.

1. Remove the lockscrew from the ratchet

adjustment wheel.

2. With a screwdriver, adjust the ratchet wheel

from the locator side of the tool.

3. Observe the ratchet adjustment wheel. If a

tighter crimp is required, rotate the adjustment

wheel COUNTERCLOCKWISE to a

higher–numbered setting. If a looser crimp is

required, rotate the adjustment wheel

CLOCKWISE to a lower–numbered setting.

4. Replace the lockscrew.

5. Make a sample crimp and measure the crimp

height. If the dimension is acceptable, replace and

secure the lockscrew. If the dimension is

unacceptable, continue to adjust the ratchet, and

again measure a sample crimp.

8. MAINTENANCE

Ensure that the tool and dies are clean by wiping

them with a clean, soft cloth. Remove any debris with

a clean, soft brush. Do not use objects that could

damage the tool. When not in use, keep handles

closed to prevent objects from becoming lodged in

the crimping dies, and store in a clean, dry area.
