month, the inspection frequency should be based on 
the amount of use, ambient working conditions, 
operator training and skill, and established company 
standards. These inspections should be performed in 
the following sequence:

A. Visual Inspection

1. Remove all lubrication and accumulated film by 
immersing the tool (handles partially closed) into a 
suitable degreaser that will not affect paint or plastic 
material.

2. Make certain all retaining pins are in place and 
are secured with the proper retaining rings. If 
replacements are necessary, refer to Figure 5.

3. Close the tool handles until the ratchet releases, 
and then allow the handles to open freely. If they do 
not open quickly and fully, then the spring is 
defective and must be replaced (see Section 5, 
REPLACEMENT AND REPAIR).

4. Inspect the tool, with special emphasis on 
checking for worn, cracked, or broken crimping 
dies. If damage to any part of the head is evident, 
return the tool for evaluation and repair (see Section 
5, REPLACEMENT AND REPAIR).

B. Crimp Height Inspection

Crimp height inspection is performed through the 
use of a micrometer with a modified anvil, 
commonly referred to as a crimp height comparator. 

TE does not market crimp height comparators. 
Refer to Instruction Sheet 408-7424 for detailed 
information on obtaining and using a crimp height 
comparator.

Proceed as follows:

1. Refer to the chart in Figure 4 and select a contact 
and a wire (maximum size) for each crimp section.

2. Refer to Section 3, 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 chart, 
the tool is considered dimensionally correct. If not, 
return the tool for evaluation and repair (refer to 
Section 5, REPLACEMENT AND REPAIR).

C. Ratchet Inspection

Obtain a 0.025-mm [.001-in.] shim that is suitable for 
checking the clearance between the bottoming 
surfaces of the crimping dies. Proceed as follows:

1. Select a contact and maximum size wire for the 
hand tool.

2. Position the contact and wire between the 
crimping dies, as described in Section 3, 
CRIMPING PROCEDURE.

3. Holding the wire in place, squeeze the tool 
handles together until the CERTI-CRIMP ratchet 
releases. Hold the handles in this position, 
maintaining just enough tension to keep the dies 
closed.

4. Check the clearance between the bottoming 
surfaces of the crimping dies. If the clearance is 
0.025 [.001] or less, the ratchet is satisfactory. If the 
clearance exceeds 0.025 [.001], the ratchet is out of 
adjustment and must be repaired.

If the tool conforms to these inspection procedures, 
lubricate it with a thin coat of any good SAE 20 motor 
oil and return it to service.

5. REPLACEMENT AND REPAIR

The parts listed in Figure 5 are customer- replaceable. 
A complete inventory can be stocked and controlled to 
prevent lost time when replacement of parts is 
necessary. Order replacement parts through your 

TE Connectivity, or call 1-800-526-5142, or send a 
facsimile of your purchase order to 1-717-986-7605, or
