5. ADJUSTMENTS
5.1. Ratchet Adjustment (Figure 5)
The tool ratchet mechanism features an adjustment wheel with numbered settings. The adjustment wheel
controls the amount of handle pressure exerted on the jaws during crimping. If the crimp 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 front 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. Re-assemble the lockscrew.
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. If a proper crimp
cannot be obtained, the tool or die assembly must be replaced. Refer to Section 7.
NOTE
The tool is set at the No. 7 ratchet setting at the factory. This setting assures the proper crimp height for solid wire and
accounts for the maximum tolerance in the tooling. You can readjust your tool to a lower setting, (No. 4, minimum), as long as
you achieve the proper insertion depth, 6.02 ±0.13 [.237 ±.005). See the applicable application specification.
5.2. Wire Stuffer Adjustment
If the wire stuffer is not assembled onto the insulation stuffer or if correct alignment of these two parts is
unsure, proceed with the following:
1. Install the wire stuffer onto the insulation stuffer using the 4-40 UNC .621 in. socket head cap screw
included with the die assembly. Refer to Figure 2.
NOTE
DO NOT tighten the screw. If the screw is tight, loosen it.
2. Close the tool handles until the ratchet releases, then allow the handles to open FULLY. Insert a
modular plug (without cable) into the crimping chamber.
3. Close the tool handles, and hold.
4. Insert a key into the socket head cap screw (retaining the wire stuffer), and tighten the screw.
5. Allow the handles to open, and remove the crimped modular plug. The wire stuffer will be held in its
proper position.
