tool handles and allowing them to open FULLY.

4. MAINTENANCE AND INSPECTION PROCEDURE
Tyco Electronics 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.
The hand tool is inspected before being shipped;
however, Tyco Electronics recommends that the tool
be inspected immediately upon its arrival at your
facility to ensure that the tool has not been damaged
during shipment.
Due to the precision design, it is important that no
parts of these tools be interchanged except those
replacement parts listed in Figure 6.
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.
