6.2. Periodic Maintenance

Regular inspections should be performed by your

quality control personnel with a record of these control

inspections remaining with the personnel responsible

for the tool. TE recommends one inspection a month;

however, operator training and skill, amount of use,

ambient working conditions, and your company's

established standards are all factors in establishing

frequency of inspections.

These inspections should be performed in the

following sequence:

1. Remove any accumulated film with a suitable

cleaning agent that will NOT affect plastic material.

2. Make sure all components are in place and

properly secured. See Figure 7.

3. Make a few test terminations and inspect the

terminations in accordance with Section 5,

INSPECTION.

4. Check for chipped, cracked, worn, or broken

areas. If damage is evident, repair if necessary. See

Section 7, REPLACEMENT AND REPAIR.

6.3. Occasional Maintenance

Because this tool shears wires before insertion, wear

of the shearing surfaces can be expected as a normal

operating condition. Since wire size, insulation

diameter and hardness are all variables, a reasonable

life expectancy of the shearing edges cannot be

determined.

Shearing occurs along the edge where the inserter

rides against the shear. When the operator of the tool

starts to notice wire ends that are not cleanly cut, or if

excessive force becomes necessary to shear the

wires, it is time to change or replace the two

components that do the shearing. Refer to Figure 6

and proceed as follows:

1. To change the position of the shear, remove the

cover of the terminating head by loosening the two

4-40 socket head cap screws which hold the head

in place. Carefully, lift off the cover. See Figure 6.

NOTE

i

DO NOT lift the inserter off with the cover.

2. Lift off the inserter. (Make note as to which side is

in contact with the shear.)

3. Lift off the shear. Rotate the shear 180° so that

the surface that was facing down is now facing up.

Place the shear back in place.

4. Replace the inserter, making sure that the

surface (that was in contact with the shear when

disassembling the tool) is now rotated 180° away

from the shear.

Make sure that the roll pin going through the

inserter is engaged in the slot of the link.

5. Replace the cover. Align the edges of the

terminating head, shear, and cover and tighten the

two 4-40 socket head cap screws.

NOTE

i

This procedure can only be done one time for each

set of inserter and shear. When the second

shearing edge becomes dull, replacement of the

inserter and shear will be necessary.

CAUTION

!

Attempts to sharpen the inserter or shear might

cause the inserter to be out of position during wire

insertion and cause damage to the connector or

tool.
