4. Crimp the terminal. Bend the wire back and forth once. If the wire pulls out, set pin in No. 2 position

and repeat the test until the desired grip is obtained.

4. CRIMPING PROCEDURE

1. These tools is equipped with a CERTI-CRIMP Ratchet (see Figure 1) to ensure proper crimping. To

open the tool handles, squeeze them until the ratchet releases.

NOTE

Once the ratchet is engaged, the handles cannot be opened until they are fully closed.

2. Place the terminal in the tool so that the locator fits in the slot between the terminal insulation barrel

and the wire barrel. See Figure 2.

Figure 2

3. Close the handles until the crimping jaws close just enough to retain the terminal. See Figure 2.

CAUTION

Do not deform the terminal. Damaged product should not be used. If damaged product is evident, it should be replace with a

new one. Terminals should not be re-terminated.

4. Insert the stripped wire into the terminal until the end of the insulation butts against the locator.

5. Close the tool handles until the CERTI-CRIMP Ratchet releases. Remove the crimped terminal from

the tool.

6. For wire with insulation diameter 3.5 mm [.138 in.] and larger, first insert the wire into the terminal. The

insulation barrel will be fixed around the insulation.

7. Then follow steps 2 and 5.

5. GAGE DIMENSIONS

To ensure the tool is dimensionally correct, check the tool dimensions with a gage. See Figure 3.
