4. MAINTENANCE/INSPECTION
AMP recommends that a maintenance and inspection
program be performed periodically to ensure
dependable and uniform terminations. Frequency of
inspection depends on:
1. The care, amount of use, and handling of the
hand tool.
2. The presence of abnormal amounts of dust and
dirt.
3. The degree of operator skill.
4. Your own established standards.
4.1. Daily Maintenance
1. Remove dust, moisture, and other contaminants
with a clean brush, or a soft, lint–free cloth. Do
NOT use objects that could damage the tool.
2. Make certain that the retaining pins are in place
and that they are secured with retaining rings.
3. When the tool is not in use, keep handles closed
to prevent objects from becoming lodged in the
crimping dies. Store the tool in a clean, dry area.
4.2. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
Tools used in daily production—lubricate daily
Tools used daily (occasional)—lubricate weekly
Tools used weekly—lubricate monthly
Wipe excess oil from tool, particularly from crimping
area. Oil transferred from the crimping chambers onto
certain terminations may affect the electrical
characteristics of an application.
4.3. Periodic Inspection
1. Hand tool should be immersed (handles partially
closed) in a reliable commercial degreasing
compound to remove accumulated dirt, grease,
and foreign matter.
2. Close tool handles until the CERTI–CRIMP
ratchet releases and then allow them to open fully.
If the handles do not open quickly and fully, the
spring is defective and must be replaced. Refer to
Section 5, REPLACEMENT AND REPAIR.
