INTRODUCTION.
This instruction sheet provides application and maintenance procedures for the Hand Crimping Tool. (See Figure 1.) This tool is
designed to acept interchangeable crimping die assemblies. Read these instructions thoroughly before installing dies and using the
tool.
2. DESCRIPTION.
The Hand Crimping Tool consists of two crimping jaws, an adjustable ratchet, spring-actuated handles, two die retaining screws, and
an emergency ratchet release. The slotted design of the crimping jaws permits easy installation and removal of crimping dies. The
adjustable ratchet allows handle pressure to be set for optimum crimping die performance.
3. DIE INSTALLATION AND REMOVAL.
Select the desired die assembly, remove the die retention screws from the tool jaws, and proceed as follows:
3.1 Shouldered Dies (Figure 2)
1. Place the upper die in the stationary jaw of the tool frame.
2. Insert a die retention screw through the jaw and die and tighten the screw so that the die is held in place, but do not tighten the
screw completely at this point. Note: Die assembies with center contact crimp sections should be installed with the center contact
crimp section toward the front of the tool jaws as shown in Figure 2.
3. Place the lower die in the moving jaw of the tool frame. Install a die retention screw through the jaw and die and tighten the screw
so that the die is held in place, but do not tighten the screw completely at this point. Note: The tool ratchet has detents that are
audible as seven “clicks” as the handles are closed. The ratchet releases on the seventh “click”.
4. Slowly close the tool handles, allowing the dies to mate and/or align. Continue closing the tool handles until the ratchet makes the
sixth “click,” then tighten both die retention screws until snug.
5. To remove the die assembly, close the tool handles until the ratchet releases, and allow the handles to open fully. Loosen and
remove the die retention screws and slide the dies out of the tool jaws.
3.2 Pinned Dies (Figure 3).
1. Install wire and insulation anvil dies, with the chamfers facing the front of the tool, and with the die markings facing outward, into the
jaw of the frame assembly.
2. Insert the die retaining pins and the short die retention screw. Do not tighten the screw completely.
3. Install the wire and insulation crimper dies, with the chamfers facing the front of the tool, and with the die markings facing outward,
into the stationary jaw of the frame assembly.
4. Insert the die retaining pins the long die retention screw. Do not tighten the screw completely.
5. Slowly close the tool handles, allowing the dies to mate and/or align. Continue closing the tool handles until the ratchet makes the
sixth “click,” then tighten both die retention screws until snug.
6. Install the locator assembly and tighten the hex nut.
7. Reverse the procedure to remove the die assembly.

4.1 Daily Maintenance.

Operators of this tool must be made aware of, and responsible

for, the following steps of daily maintenance:
1. Remove dust, moisture, and any other contaminants from the
tool with a clean, soft brush, or a clean, soft, lint–free cloth.
Do NOT use hard or abrasive objects that could damage the
tool.
2. Make certain that the pivot 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 No. 20 motor oil.
Do not oil excessively.
4. When the tool is not in use, keep handles closed to prevent
objects from becoming lodged in the crimping jaws. Store the
tool in a clean, dry area.
4.2 Periodic Inspection.
Regular inspections of the tool should be performed by quality
control personnel. A record of scheduled inspections should
remain with the tool or be supplied to supervisory personnel

5. CRIMP HEIGHT ADJUSTMENT

The tool frame assembly features a ratchet
mechanism and adjustment wheel with a range
of settings. The ratchet mechanism ensures that
the tool has completed the cycle. The adjust-
ment wheel controls the amount of handle pres-
sure exerted on the tool jaws and crimping dies

during the crimping procedure. Although the

ratchet is preset prior to shipment, it is important
that you verify the crimp height. Also, general
use and subsequent wear may cause the tool to go out of adjustment. It is recommended that the crimp height be inspected — and
adjusted, if necessary — on a regular basis by quality control personnel.
1. Crimp a contact onto a properly–prepared wire of the correct size.
2. If the crimp height is greater than recommended, remove the ratchet wheel adjustment screw and rotate the
adjustment wheel COUNTERCLOCKWISE to a higher setting. Repeat as required.
3. If the crimp height is less than recommended, remove the ratchet wheel adjustment screw and rotate the adjustment
wheel CLOCKWISE to a lower setting. Repeat as required.
4. If the crimp cannot be made to conform to the dimensions provided in the appropriate product application
specification, the tool and/or dies are defective and must be replaced.
