4. MAINTENANCE AND INSPECTION

4.1. 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 dies.

2. Make sure that dies are properly aligned and

that die holding screws are in place and secured.

3. Make certain that all surfaces are protected with

a thin coat of any good SAE 20 motor oil. Do not

oil excessively.

4. When dies are not in use, store in a clean, dry

area.

4.2. Inspection

Regular inspections should be performed with a

record of inspections remaining with the dies and/or

supervisory personnel responsible for them. One

inspection per month is recommended; however,

amount of use, working conditions, operator training

and skill, and established company standards should

determine frequency of inspection. The inspection

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.

SAE is a trademark of SAE International Corporation.

2. Make sure all die holding screws are in place

and secured.

3. Check all bearing surfaces for wear. 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.

B. Crimp Height Inspection

This inspection incorporates the use of a crimp height

comparator (micrometer with a modified anvil) as

shown in Figure 4. Detailed information on obtaining

and using a crimp height comparator can be found in

instruction sheet 408--7424.

Proceed as follows:

1. Refer to Figure 4 and select a contact and

maximum size wire for the dies.

2. Refer to Section 3, CRIMPING PROCEDURE,

and crimp the contact accordingly.

3. Using the crimp height comparator, measure the

wire barrel crimp height as shown in Figure 4.

If the crimp height conforms to that shown in Figure 4,

the dies are considered dimensionally correct and

should be lubricated with a thin coat of any good SAE

20 motor oil. If not, the dies must be repaired or

replaced. Refer to Section 5, REPLACEMENT AND

REPAIR.

5. REPLACEMENT AND REPAIR

Customer--replaceable parts are listed in Figure 5.

A complete inventory should be stocked and

controlled to prevent lost time when replacement of

parts is necessary. Parts other than those listed

should be replaced by Tyco Electronics to ensure

quality and reliability. Order replacement parts
