CAUTION: Never operate this tool without the supplied safety shield in place. Never place fingers in the tool
nests.
3. Push on the wire to assure it is still fully seated in the terminal. The wire’s end should butt against the
wire stop stamped into each terminal. See Figure 2 and 3. Cycle the tool.
4. Remove the crimp and inspect for proper crimp location. Molex offers a Crimp Inspection Handbook for
closed barrel industrial product. See our website or contact your sales engineer.
5. If the insulation part of the crimp needs to be adjusted, first disconnect the air source and loosen the M4
screw on the bottom tool jaw and insert a 3/32” hex wrench (supplied) into the bottom of the lower die.
See Figure 4. A clockwise (CW) rotation decreases insulation crimp while a counter-clockwise (CCW)
rotation increases insulation crimp. After adjusting retighten the M4 screw. Reconnect the air source.
Note: Whenever crimping without the locator, make sure the seam of the terminal is oriented up or down in
the tool if using unbrazed product, as this will provide higher pull force values.
Maintenance
It is recommended that each operator of the 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 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. Do not oil excessively. This tool was engineered for durability, but like any fine piece of
equipment it needs cleaning and lubrication for a maximum service life of trouble-free crimping. Use a
light oil such as 30 weight automotive oil at the oil points shown in Figure 4, every 5,000 crimps or
monthly will significantly enhance the tool life and ensure a stable calibration.
4. When tool is not in use store the tool in a clean, dry area.
