3. CRIMPING PROCEDURE
Strip the wire to the length indicated, taking care not
to cut the wire strands. Select an applicable contact
and identify the appropriate crimping chamber
according to the wire size markings on the tool.
NOTE: Use 24-28 crimp section for 24-28 AWG
wire. Use 20-24 crimp section for 20-22 AWG wire.
Refer to Figure 2, and proceed as follows:
1. Hold the tool so that the front is facing you.
Squeeze tool handles together and allow
them to open fully.
2. Insert the contact (mating end first) into the
hole in the locator which corresponds with
the appropriate crimping chamber. Make
sure that the open “U” of the wire barrel and
insulation barrel face up towards numerical
markings on tool.
CAUTION Make sure that both sides of the
contact insulation barrel are started
evenly into the crimping chamber.
Do NOT attempt to crimp an
improperly positioned contact.
3. Hold the contact in position, and squeeze
the tool handles together until ratchet
engages sufficiently to hold the contact in
position. Do NOT deform insulation barrel
or wire barrel.
3. Insert stripped wire into contact insulation
and wire barrels until wire and insulation are
visible in inspection window, as shown in
Figure 2.
5. Holding the wire in place, squeeze the tool
handles together until ratchet releases.
Allow tool handles to open and remove
crimped contact.
4. CRIMP PULL TEST
1. Refer to Section 3, CRIMPING
PROCEDURE, and crimp the contact
accordingly to achieve pull test in Figure 3.

7. DAILY MAINTENANCE
Properly crimped terminals are controlled by the
following maintenance and inspection
procedures.
1. Clean all dust, dirt, moisture and other
foreign matter from the crimp jaws that could
damage the crimp area of the dies.
DO NOT immerse tool in cleaning solution.

2. The pivot pin and ratcheted pawl-bearing
surface should be lubricated to ensure a
smooth operation.
DO NOT spray oil into tool to lubricate
3. When storing the tool, close the handles
until the ratchet pawl is about to be released
from the tooth of the ratchet. This will help
prevent the dies from being damaged.
8. VISUAL INSPECTION
The crimping dies should be inspected on a
regular basis to ensure that they have not
become worn or damaged.
1. Clean tool die area with solvent or brush.
DO NOT immerse tool in cleaning solution
2. Check crimp area of die for damages.
3. If tool jams or locks, check the ratchet for
dirt and lubrication.
9. CARE OF TOOL
There is virtually no maintenance required. However,
it is a good practice to keep indenter tips free of
residual color band deposits and other debris. A
small wire brush may be used for this purpose.
WE STRONGLY RECOMMEND THAT YOU
DO NOT:
•immerse tool in cleaning solution
•spray oil into tool to lubricate
•attempt to disassemble tool or make repairs
THIS IS A PRECISION HAND CRIMPING TOOL
