3. Using a crimp height comparator, measure the
wire barrel crimp height as shown in Figure 4. If the
crimp height conforms to that shown in the table,
the tool is considered dimensionally correct. If not,
the tool must be adjusted. Refer to Section 6,

6. CRIMP HEIGHT ADJUSTMENT (Figure 5)
1. Remove the lockscrew from the ratchet
adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel from
the locator side of the tool.
3. Observe the ratchet adjustment wheel. If a tighter
crimp is required, rotate the adjustment wheel
COUNTERCLOCKWISE to a higher-numbered
setting. If a looser crimp is required, rotate the
adjustment wheel CLOCKWISE to a lower-
numbered setting.
4. Replace the lockscrew.
5. Make a sample crimp and measure the crimp
height. If the dimension is acceptable, replace and
secure the lockscrew. If the dimension is
unacceptable, continue to adjust the ratchet, and
again measure a sample crimp.
7. MAINTENANCE
Ensure that the tool and dies are clean by wiping them
with a clean, soft cloth. Remove any debris with a
clean, soft brush. Do not use objects that could
damage the tool. When not in use, keep handles
closed to prevent objects from becoming lodged in the
crimping dies, and store in a clean, dry area.

8. VISUAL INSPECTION
The crimping dies should be inspected on a regular
basis to ensure that they have not become worn or
damaged. Inspect the crimp sections for flattened,
chipped, worn, or broken areas. If damage or
abnormal wear is evident, the tool must be replaced.
See Section 9, REPLACEMENT.
