OPERATION
1. Open the tool by squeezing the handles together until the ratchet releases.
2. Partially close the tool until the terminal is held in place.
3. Place a wire in the terminal and up against the locater blade.
4. Close the tool until the ratchet releases. You only make one crimp; the jaws will
crimp the full length of the crimping area.
5. Carefully remove the crimped terminal.
CRIMP THE CONNECTOR
There are several arguments for and against using solid core wire with crimp
connections. Many believe crimping to solid core wire creates a weak point in the wire,
which can lead to breakage. There is also a greater chance for a crimp connection to
come loose with solid core wire because the wire will not conform to the terminal as
well. If you must use solid core wire, it is a good idea to solder the wire in place after
you crimp it.
•Choose the correct wire size for the terminal size, or vice versa and strip the wire.
•The amount of exposed wire should be equal to the length of the metal barrel
on the connector, usually around ¼”.
• If the stripped wire fits up into the metal portion of the barrel with little or no
free space, the connector is the right size.
Remember: If the wire is too loose or does not fit in the barrel, the wrong size of either
the wire or the connector was chosen.
•The wire should then be inserted until the insulation on the wire touches the
end of the barre.
•Insert the wire and the terminal into the crimper.
•The color of the terminal’s insulation needs to be matched with the same
color on the crimping tool.
•If the terminal’s insulation is red, use the spot marked by the red dot on the
crimpers.
•Alternatively, if the crimper does not have color markings, use the gauge
markings on the side.
The terminal should be sitting horizontal with the barrel side up. The tool is then held
perpendicular to the terminal and placed over the barrel, nearest to the ring (or other
connection type). To finish the crimp, the tool is squeezed with a considerable force. In
general, it is almost impossible to ‘over crimp’ a connection.
NOTES
1. The head (die) is interchangeable.
2. The release valve is not accessible with your finger. Use a small screwdriver to
release handles.
3. Adjustable Knob-Will tighten or loosen the tension on the crimper.
MAINTENANCE
1. Remove dust, moisture and other contaminants with a clean brush, or soft, lint
free cloth
2. Do not use any abrasive materials that could damage the tool
3. Make certain all pins; pivot points and bearing surfaces are protected with a
thin coat of high quality machine oil
4. When tool is not in use, keep the handles closed to prevent objects from
becoming lodged in crimping dies. Store the tool in a clean dry area.
Note: Pliers are NOT crimpers. Neither are hammers, vises, needle nose pliers or flat
rocks.
A good crimper, when used correctly, will make a cold weld between the wire and the
barrel of the connector. If you were to cut a well-executed crimp in half, you would
see a solid form of wire and connector. Using the wrong tool will not achieve a good
crimp!
Why is this level of perfection required? A poor crimp leaves air pockets between the
wire and connector. Air pockets allow moisture to collect, moisture causes corrosion,
corrosion causes resistance, resistance causes heat and may ultimately lead to
breakage.
