5.1. Daily Maintenance
It is recommended that each operator of the dies be
made aware of-and responsible for-the following steps
of daily maintenance:
1. Remove dust, dirt, and other contaminants with a
clean brush, or a soft, lint-free cloth. Do NOT use
objects that could damage the dies.
2. Make certain the dies are protected with a THIN
coat of any good SAE 20 motor oil. Do NOT oil
excessively.
3. When the dies are not in use, mate them and
store 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 dies and/or be supplied to
supervisory personnel responsible for the dies.
Though 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:
A. Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the dies in a suitable commercial
degreaser that will not affect paint or plastic
material.
2. Make sure all die components are in place. If
replacements are necessary, refer to the
replacement parts listed in Figure 5.
3. Check components for wear. Remove and
replace worn components.
4. Inspect the crimp area for flattened, chipped,
cracked, worn, or broken areas. If damage is
evident, the dies must be repaired before returning
them to service (see Section 6, 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 table in Figure 2 and select a contact
and a wire for each crimp section. Use the
MAXIMUM size wire for each crimp section.
2. Refer to Section 4, CRIMPING PROCEDURE,
and crimp the contacts 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 height, the tool is
considered dimensionally correct. If not, the tool
must be returned to AMP for evaluation and repair.
See Section 6, REPLACEMENT AND REPAIR.

6. REPLACEMENT AND REPAIR
Replaceable parts are listed in Figure 5. Parts other
than those listed in Figure 5 should be replaced by TE
to ensure quality and reliability of the tool. Order
replacement parts through your TE representative, or
