6. RATCHET (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. Re--assemble the lockscrew.
5. Make a sample crimp and measure the crimp
height. 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.

damaged. Inspect the crimping chambers for
flattened, chipped, worn, or broken areas. If damage
or abnormal wear is evident, the tool must be
replaced. See Section 9, REPLACEMENT AND
REPAIR.
