2. Slide the ferrule forward over the braid until the
ferrule butts against the shoulder on the connector
body.
3. Place the ferrule in the ferrule crimping chamber
of the anvil die so that the shoulder on the
connector body butts against the edge of the die.
See Figure 3.
4. Holding the assembly in place, close the tool
handles until the ratchet releases.
5. Remove crimped assembly from the crimping
dies.
5. CRIMP HEIGHT ADJUSTMENT (Figure 4)
The tool frame assembly ratchet mechanism features
an adjustment wheel with numbered settings. If the
crimp height is not acceptable, adjust the ratchet as
follows:
1. Remove the lockscrew from the ratchet
adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel
from the opposite side of the tool.
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.
4. Replace the lockscrew.
5. Make a sample crimp and measure the crimp
height. If the crimp height is acceptable, secure the
lockscrew. If the dimension is unacceptable,
remove lockscrew and continue to adjust the
ratchet, and again measure a sample crimp.
6. MAINTENANCE AND INSPECTION
6.1. Daily Maintenance
It is recommended that each operator of the tool with
the die assembly be made aware of, and responsible
for, the following four steps of daily maintenance:
1. Remove dust, moisture, and other contaminants
with a clean, soft brush, or a clean, soft, lint--free
cloth. Do NOT use any objects that could damage
the dies or tool.
2. Make sure that the proper die retaining 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.
4. When the dies are not in use, mate and store
them in a clean, dry area.
6.2. Periodic Inspections
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 per month, the inspection frequency should
be based on amount of use, working conditions,
operator training and skill, and established company
standards. These inspections should be performed in
the following sequence:
Screwdriver
Ratchet
Adjustment
Wheel
Lockscrew (Typ)

A. Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the dies in a suitable commercial
degreaser.
2. Make certain all die retaining screws and die
components are in place and secured. If
replacements are necessary, refer to Section 7,
REPLACEMENT.
3. Inspect the crimp area for flattened, chipped,
worn, cracked, or broken areas. If damage is
evident, the dies must be replaced (see Section 7,
REPLACEMENT).
B. Gaging the Crimping Chamber
This inspection requires the use of a plug gage
conforming to the diameters provided in Figure 5. TE
does not manufacture, or market, these gages.
Proceed as follows:
1. Mate the dies until it is evident that they have
bottomed. Hold the dies in this position by holding
the tool handles closed with moderate pressure.
