6. CRIMP INSPECTION
Inspect crimped terminals and splices by checking the
features described in Figure 4. Use only terminals
and splices that meet the conditions shown in the
“ACCEPT” column. “REJECT” terminations can be
avoided through careful use of instructions in
4. When the crimping head is not in use, store it in
a clean, dry area.
Sections 4 and 5, and by performing regular crimping
head maintenance as described in Section 7.
7.2. Periodic Inspection
Regular inspections should be performed by quality
control personnel. A record of scheduled inspections
should remain with the crimping head or be supplied
to supervisory personnel responsible for the crimping
head. Though recommendations call for at least one
inspection a month, the frequency should be based
on amount of use, working conditions, operator
training and skill, and your established company
policies. These inspections should include a visual
inspection (Paragraph 7.3) and a crimping chamber
inspection (Paragraph 7.5).
7. MAINTENANCE AND INSPECTION
To avoid personal injury, ALWAYS disconnect air
supply from pneumatic tool before performing
maintenance or inspection.
DANGER
It is recommended that a maintenance and inspection
program be performed periodically to ensure
dependable and uniform terminations. The pneumatic
crimping head should be inspected once a month.
7.3. Visual Inspection
1. Remove all lubrication and accumulated film by
immersing the crimping head in a suitable
commercial degreaser that will not affect paint or
plastic.
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
crimping head.
2. Make certain all components are in place. If
replacements are necessary, refer to Section 8,
REPLACEMENT AND REPAIR.
2. The type and size of the product crimped.
3. The degree of operator skill.
3. Check all bearing surfaces for wear. Make sure
the rollers turn freely with minimal resistance.
Replace worn parts.
4. The presence of abnormal amounts of dust and
dirt.
4. Inspect crimp area for flattened, chipped, or
broken areas. See Figure 5. Replace worn or
damaged parts.
5. Your own established standards.
Each crimping head is thoroughly inspected before
packaging. Since there is the possibility of damage
during shipment, new crimping heads should be
inspected immediately upon arrival at your facility.
