3. Observe the ratchet adjustment wheel. If a tighter
crimp is required, rotate the adjustment wheel
counterclockwise to a higher-numbered setting. If a
looser crimp is required, rotate the adjustment
wheel clockwise to a lower-numbered setting.

5. Make a sample crimp. If the crimp is acceptable,
the adjustment setting is correct. If the crimp is
unacceptable, continue to adjust the ratchet, and
again measure a sample crimp.
6. 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 408-7224 for detailed information on obtaining
and using a crimp height comparator.
Proceed as follows:
1. Refer to Figure 5, and select a maximum size
wire for each crimping chamber.
2. Crimp the contacts according to Section 4.
3. Using a crimp height comparator, measure the
wire barrel crimp height as shown in Figure 4. If the
crimp height conforms to the dimension, the tool
assembly is considered dimensionally correct. If
not, the tool frame must be adjusted. Refer to
Paragraph 5.2, Crimp Height Adjustment.
7. MAINTENANCE AND INSPECTION
7.1. Maintenance
1. Ensure that the tool frame and dies are clean by
wiping them with a clean, soft cloth. Remove any
debris with a clean, soft brush. Do not use objects
that could damage any components.
2. When not in use, keep tool handles closed to
prevent objects from becoming lodged in the dies,
and store in a clean, dry area.

3. Remove all lubrication and accumulated film from
the dies by immersing the dies in a suitable
commercial degreaser.
7.2. Visual Inspection
1. Inspection of the tool and dies should be made on
a regular basis to ensure that they have not become
worn or damaged.
2. Make sure that the proper die retaining screws
are properly secured.
3. Inspect the crimping chambers of the die
assembly for flattened, chipped, worn, or broken
areas. If damage or abnormal wear is evident, the
dies must be replaced. Refer to Section 7,
REPLACEMENT AND REPAIR.
8. REPLACEMENT AND REPAIR
Available separately, Repair Kit 679221-1 includes a
replacement nut and a variety of pins, rings, screws,
and springs. If the dies are damaged or worn
excessively, they must be replaced.
Order the repair kit, tool assembly, and die assembly
through your representative, or call 1-800-526-5142,
