2. Position the contact and wire between the
crimping jaws, according to Section 3, CRIMPING
PROCEDURE (Steps 1 through 6). Holding the wire
in place, squeeze the tool handles together until the
ratchet releases. Hold the tool handles in this
position, maintaining just enough pressure to keep
the jaws closed.
3. Check the clearance between the bottoming
surfaces of the crimping jaws. If the clearance is
025 mm [.001 in.], or less, the ratchet is satisfactory.
If clearance exceeds .025 mm [.001 in.] the ratchet
is out of adjustment and must be adjusted (see
Section 5, TOOL ADJUSTMENT).
E. Tool Force Values
1. Apply force as shown until ratchet releases. The
force at a point 44.45 mm [1.75 in.] from handle
ends should be 35 to 45 pounds. See Figure 4.
Apply Force as Shown Until Ratchet Releases.
The force at Point 44.45 mm [1.75 in.] from the
Handle Ends Should Be 1.88-2.42 kg [35-45 lb.]
