5.1. Daily Maintenance

1. Immerse the tool (handles partially closed) in a

reliable commercial degreasing compound to

remove accumulated dirt, grease, and foreign

matter. When degreasing compound is not

available, the tool may be wiped clean with a soft,

lint-free cloth. DO NOT use hard or abrasive objects

that could damage the tool.

2. Make certain that the retaining pins are in place

and that they are secured with retaining rings.

3. All pins, pivot points, and bearing surfaces should

be protected with a THIN coat of any good SAE 20

motor oil. DO NOT oil excessively.

4. When the tool is not in use, keep the handles

closed to prevent objects from becoming lodged in

the crimping dies. Store the tool in a clean, dry area.

5.2. Periodic Inspection

A. Lubrication

Lubricate all pins, pivot points, and bearing surfaces

with any good SAE† 20 motor oil as follows:

Wipe excess oil from the tool, particularly from the

crimping area. Oil transferred from the crimping area

onto certain terminations may affect the electrical

characteristics of an application.

B. Visual Inspection

1. Close the tool handles until the ratchet releases

and then allow them to open freely. If they do not

open quickly and fully, the spring is defective and

must be replaced. See Section 6, REPLACEMENT

AND REPAIR.

Some tools do not have handle return springs. This

inspection does not apply to those tools.

2. Inspect the head for worn, cracked, or broken

crimping dies. If damage is evident, return the tool

for evaluation and repair. See Section 6,

REPLACEMENT AND REPAIR.

C. Gaging the Crimping Chamber

This inspection requires the use of plug gages

conforming to the dimensions provided in Figure 9.

To gage the crimping chamber, proceed as follows:

†SAE is a trademark.

If gaging the crimping chamber is not required,

inspect the die closure using an alternate

procedure, i.e., the "Insulation Crimp Adjustment"

(see Section 4) and "Visual Inspection" (see

Paragraph 5.2.B).

1. Remove traces of oil or dirt from the crimping

chamber and plug gage.

2. Insert each insulation crimp adjustment pin into

Position 1. See Figure 10.

3. Close the tool handles until the crimping dies

bottom, and hold in this position. DO NOT force

beyond initial contact.

4. Press and hold the locator down.

5. Carefully insert the GO element into the crimping

chamber as shown in Figure 10; DO NOT force it.

For the wire barrel section of the crimping chamber,

the GO element must pass completely through the

crimping chamber. For the insulation barrel section,

the GO element must pass through the length of the

section but will stop against the wire barrel section.

6. In the same manner, try to insert the NO-GO

element into the crimping chamber as shown in

Figure 10. The NO-GO element may begin entry,

but may not pass through the crimping chamber.

If the crimping chamber conforms to the gage

inspection, the tool is considered dimensionally

correct, and should be lubricated with a THIN coat of

any good SAE 20 motor oil. If not, return the tool for

evaluation and repair. See Section 6, REPLACEMENT

AND REPAIR.

5.3. Ratchet Inspection

Check the ratchet to ensure that the ratchet does not

release prematurely, allowing the dies to open before

they have fully bottomed. Proceed as follows:

1. Remove traces of oil or dirt from the bottoming

surfaces of the dies.

2. Obtain a 0.025 mm [.001 in.] shim that is suitable

for checking the clearance between the bottoming

surfaces of the dies.

3. Select a terminal or splice and maximum size

wire for the terminal or splice.

4. Position the terminal or splice in the crimping

chamber according to Section 3, CRIMPING

PROCEDURE. Holding the wire in place, squeeze

the tool handles together until the ratchet releases.

Hold the tool handles in this position, maintaining

just enough pressure to keep the dies closed.

5. Check the clearance between the bottoming

surfaces of the dies. If the clearance is 0.025 mm

[.001 in.] or less, the ratchet is satisfactory. If

clearance exceeds 0.025 mm [.001 in.], the ratchet

is out of adjustment and must be repaired. See

Section 6, REPLACEMENT AND REPAIR.
