OPERATION
Open the tool by squeezing the handles together,at the end of the
closing stroke, the ratchet mechanism will release the handles, and the
hand tool will spring open.
Crimping Terminals
1. Lift the locator blade and place the terminal into the correct die
profile (A or B),release the locator blade. Notall tools are equipped
witha locator or locator blade.
2. Partially close the tool until the terminal is held in place, (See Figure
2).
3. Place a wire into the terminal and up against the locator blade,(See Figure 3). On tools without locators line
the wire up with the conductor and insulation grips
visually.
4. Close the tool until the ratchet releases, (See Figure
4).
5. Lift the locator blade or wire stop up.
6. Carefully remove the crimped terminal.
Maintenance
Itis recommended that each operator ofthe tool be made aware of,and responsible for, the following
maintenance steps:
1. Remove dust, moisture, and other contaminants with a clean brush, or soft, lint free cloth.
2. Do not use any abrasive materials thatcould damage the tool.
3. Make certain all pins;pivot points and bearing surfaces are protected with a thin coat of high quality machine
oil. Do notoil excessively.
4. When tool is not in use,keep the handles closed to preventobjects frombecoming lodged in the crimping
dies, and store the tool in a clean, dry area.
Miscrimps or Jams
Should this tool ever become stuck or jammed in a partially closed position, Do Not force the handles open or
closed. The tool will open easily by lifting the ratchet release lever (See Figure 4).

How To Adjust Tool Crimp Force (See Figure 4)
Itmay be necessary over the life ofthe tool to adjusttool-crimping force. Listed below are the steps required to
adjust the crimping force ofthe hand tool to obtain proper crimp conditions:
1. Remove the screw and washer. Located over the adjustmentring.
2. Lift the adjusting ring slightly, off of the locating pin.
3. Turn the adjusting ring in the desired direction (L= less force, T= more force) to increase or decrease crimp
pressure.
4. Press the adjusting wheel flat againstthe tool and engage the locking pin.
5. Replace the washer and screw.
6. Check the crimp specifications after tool crimp force is adjusted.
Warranty
This tool is for electrical terminal crimping purposes only. This tool is made of the best quality materials. All vital
components are long life tested. Alltools are warranted to be free ofmanufacturing defects for a period of 30
days. Should such a defect occur, we would exchange the tool free of charge. This will not be applicable to
altered,misused, or damaged tools. This toolis designed for hand use only. Any clamping, fixturing,or use of
handle extensions voids this warranty.
Hand held crimping tools are intended for low volume,prototyping, or repair requirements only.
Notes:
1. This tool should only be used for the terminals and wire gauges specified on this sheet.
2. This tool is not adjustable for crimp height, however crimp force is adjustable (See instructions above).
Variations in tools, terminals, wire stranding and insulation types may affectcrimp height.
3. This tool is intended for standard conductor sizes. Itmay notgive a good insulation crimp support for all
insulation sizes.
4. Molex does not repair hand tools (see warranty above) The replacement parts listed are the only parts
available for repair. Ifthe handles or crimp tooling is damaged or worn,a new tool must be purchased.
5. Pull force should be used as the final criteria for an acceptable crimp. Pullforce is measured with no
influence from the insulation crimp. The insulation should be stripped long (1/2 in.) so the insulation grips
on the terminal do notgrip the wire insulation or the conductor. Refer to Molex Quality Crimping
Handbook 63800-0029 for additional information on crimping and crimp testing.
6. Molex does not certify crimp handtools.
