Through TE test laboratories and the inspection of production assembly, the procedures described herein have
been established to ensure quality and reliability of TE hand crimping tools.

INSPECTION PROCEDURES
5.1.
Daily Maintenance
It is recommended that each operator of the tool be made aware of, and responsible for, the following four
steps of daily maintenance:
1. Remove dust, moisture, and other contaminants with a clean brush, or a soft lint-free cloth. Do NOT
use objects that could damage the tool.
2. Make sure the proper retaining pins are in place and secured with the proper retaining rings.
3. Make certain all pins, pivot points, and bearing surfaces are protected with a THIN coat of any good
SAE No. 20 motor oil. Do NOT oil excessively.
4. When the tool is not is use, keep the handles closed to prevent objects from becoming lodged in the
crimping dies and store the tool in a clean dry area.
5.2.
Periodic Inspection
Regular inspections should be performed by quality control personnel. A record of scheduled inspections
should remain with the tool and/or be supplied to supervisory personnel responsible for the tool. Through
recommendations call for at least one inspection a 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:
Visual Inspection
1. Remove all lubrication and accumulated film by immersing the tool (handles partially closed) in a
suitable commercial degreaser that will not affect paint or plastic material.
2. Make certain all retaining pins are in place and secured with retaining ring.
3. Close the tool handles until the ratchet releases, then allow handles to open freely. If they do not open
quickly and fully, return the tool to TE for evaluation and repair.
4. Inspect the head assembly with special emphasis on checking for worn, cracked, or broken die. If
damage to any part of the head assembly is evident, return the tool to TE for evaluation and repair.
Crimp Height Inspection
This inspection requires the use of a micrometer with a modified anvil as shown in Figure 4.
Proceed as follows:
1. Refer to the table in Figure 4 and select a contact and a wire (maximum size) for each crimp section
listed in the table.
2. Refer to Section 3, CRIMPING PROCEDURE and crimp the contact(s) accordingly.
3. Using a crimp height comparator, measure the wire barrel 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, return
the tool to TE for evaluation and repair.
TE does not market crimp height comparators. Refer to Instruction Sheet 408-7424 for detailed
information on obtaining and using a crimp height comparator.
