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 a 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. The tool was engineered for durability, but like any
other equipment, it needs cleaning and lubrication for a
maximum service life of trouble-free crimping. Light oil (such as
30 weight automotive oil) used at the oil points every 5,000
crimps or 3 months will significantly enhance the tool life.
4. Wipe excess oil from the hand tool, particularly from the
crimping area. Oil transferred from the crimping area onto
certain terminations may affect the electrical characteristics of an
application.
5. When the tool is not in use, keep the handles closed to prevent
objects from becoming 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 pressing up on the ratchet release lever in the
movable handle. See Figure 11.
How to Adjust Tool Preload (See Figure 12)
This hand tool is factory preset to 25-45 pounds preload. It may be necessary over the life of
the tool to adjust tool handle preload force. Listed below are the steps required to adjust the
crimping force of the hand tool to obtain proper crimp conditions:
1. Hold the hand tool in the palm
of your hand as shown in
Figure 12. Using your index
finger, squeeze the link toward
the top of the hand tool frame.
This will release the preload
adjustment wheel.
2. Rotate the setting wheel
counterclockwise (CCW) to
increase handle force. The
numbers will display higher. To
decrease handle force, rotate
the setting wheel clockwise
(CW).
3. Release the link to lock the
setting wheel in place.
4. Check the crimp specifications,
or conduct a pull test after tool
handle preload force is adjusted.
