5. MAINTENANCE/INSPECTION
DANGER
AVOID PERSONAL INJURY; exercise extreme
caution when using power unit. Avoid depressing
foot switch or trigger control when installing or
removing die assemblies.
Customer--replaceable parts are listed in Figure 9.
A complete inventory should be stocked and
controlled to prevent lost time when replacement of
parts is necessary.
Crimping Die Assemblies are inspected before
shipment. Tyco Electronics recommends that the die
assembly be inspected immediately upon arrival at
your facility to ensure that it has not been damaged
during shipment.
2. Inspect the crimp area for flattened, chipped,
cracked, worn, or broken areas. If damage is
evident, the dies must be replaced or repaired.
Examples of possible damaged die closure
surfaces are shown in Figure 6. If desired, you
may return them to Tyco Electronics for evaluation
and repair (see Section 6, REPAIR).

5.1. Daily Maintenance
It is recommended that each operator of the tool be
made aware of -- and responsible for -- the following
three steps of 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 dies.
2. Make certain the dies are protected with a THIN
coat of any good SAE 20 motor oil. DO NOT OIL
EXCESSIVELY.
NOTE
i
Wipe excess oil from tool, particularly from
crimping area. Oil transferred from the crimping
area onto certain terminations may affect the
electrical characteristics of an application.
3. When the dies are not in use, mate them and
store the tool in a clean, dry area.
5.2. Periodic Inspection
Tyco Electronics recommends that a maintenance
and inspection program be performed periodically to
ensure dependable and uniform terminations. Though
recommendations call for at least one inspection a
month, frequency of inspection depends on:
1. The care, amount of use, and handling of the
dies.
2. The presence of abnormal amounts of dust and
dirt.
3. The degree of operator skill.
4. Your own established standards.
A. Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the die assembly in a suitable
commercial degreaser that will not affect paint or
plastic material.

B. Gaging the Crimping Chamber
This inspection requires the use of a plug gage
conforming to the diameters provided in Figure 7.
Tyco Electronics does not manufacture or market
these gages. The following procedure is
recommended for inspecting the die closures.
1. Clean oil or dirt from the die closure areas, and
plug gage elements.
2. Assemble and adjust dies to meet the “gage
dimension” indicated in Figure 8, Detail A.
3. With dies positioned at the “gage dimension,”
inspect the bar crimp closure using the proper plug
gage. Align the GO element of the gage with the
crimping chamber. Push the element straight into
the chamber without using force. The GO element
must pass completely through the crimping
chamber without using force, as shown in Figure 8,
Detail A.
4. Align the NO--GO element with the crimping
chamber and try to insert it straight into the
chamber. The NO--GO element may start entry,
but must not pass through, as shown in Figure 8,
Detail A.
5. With dies positioned at “gage dimension,” check
the right and left rectangular crimp closures using
the proper plug gage in the same manner as Steps
4 and 5; see Figure 8, Detail B.
