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. 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 hand tool, particularly from crimping area. Oil transferred from the crimping area onto
certain terminations may affect the electrical characteristics of an application.
5. When 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
