Pneumatic Head Assembly 679304- 1
408- 4070
A maintenance and inspection program should be
performed periodically to ensure dependable and
uniform terminations. The head assembly should be
inspected once a month. Frequency of inspection
should be adjusted to suit your requirements through
experience. Frequency of inspection depends on:
1. The care, amount of use, and handling of
the head.
2. The type and size of the product crimped.
3. The degree of operator skill.
4. The presence of abnormal amounts of dust
and dirt.
5. Your own established standards.
NOTE
i
For die closure inspections and plug gage
dimensions, refer to the instruction sheet
supplied with the appropriate die assembly.
4.1. Cleaning
Remove dust, moisture, and other contaminants with
a clean, soft brush, or a soft, lint--free cloth. DO NOT
use objects or cleaning materials that could damage
the head assembly. Re--lubricate the head assembly
as instructed in Paragraph 4.3 before placing it back
into service.
4.2. Visual Inspection
1. Inspect the head assembly for missing pins and
retaining rings. If parts are missing or defective,
replace them by referring to Section 5.
2. Check all bearing surfaces for wear. Make sure
the rollers turn freely with minimal resistance.
Replace any worn parts.
3. Inspect the crimping areas of the die assembly
for flattened, chipped, or broken areas. Although
the dies may gage within permissible limits, worn
or damaged die closure surfaces may affect the
quality of the crimp.
4.3. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with a high quality grease. Use Dow Corning Molykote
paste, which is a commercially available lubricant.
Lubricate according to the following schedule:
Head used in daily production — lubricate daily
Head used daily (occasional) — lubricate weekly
Head used weekly — lubricate monthly
Wipe excess grease from the head assembly,
particularly in the die closure areas. Grease
transferred from the die closure area onto certain
terminations may affect the electrical characteristics
of a termination.
