the tool frame. Place the contact up into the
crimping chamber so that the locator drops into the
slot in the contact. Refer to Figure 3. Butt the front
end of the wire barrel against the locator.
CAUTION
!
Make sure that both sides of the insulation barrel
are started evenly into the crimping chamber.
DO NOT attempt to crimp an improperly positioned
contact.
4. Hold the contact in position, and close the tool
handles until the ratchet engages sufficiently to hold
the contact in position. DO NOT deform the
insulation barrel or wire barrel.
5. Insert the stripped wire into contact insulation
barrel and wire barrel until it is butted against the
wire stop as shown in Figure 3.
6. Holding the wire in place, close the tool handles
until the ratchet releases.
7. Allow the tool handles to open FULLY, and
remove the crimped contact.
NOTE
i
The crimped contact may stick in the crimping area;
however the contact can be removed by pushing
downward on the top of the locator (see Figure 3).
8. Check the contact crimp height, and if necessary,
adjust the crimp height
CAUTION ^{DO NOT use defective or damaged products.}

5. ADJUSTMENTS
5.1. Contact Support
The contact support is preset prior to shipment, but
minor adjustment may be necessary if the contact is
bending during crimping.
Proceed as follows:
1. Make a sample crimp and determine if the
contact is bending (upward or downward).
2. Loosen the screw that holds the contact support
onto the locator assembly.
3. Place a contact with a wire into the proper
crimping chamber, and close the tool handles until
the ratchet reaches the sixth click or until the
contact support touches the contact.
NOTE
i
The ratchet has detents that create audible clicks
as the tool handles are closed.
4. Slightly loosen the nut that holds the locator
assembly onto the tool frame.
5. Move the contact support as required to eliminate
the bending of the contact.
6. Tighten the nut, then close the handles until the
ratchet releases.
7. Remove and inspect the contact. Make another
sample crimp. If the contact is straight, tighten the
contact support screw. If the contact is still being
bent during crimping, repeat the adjustment
procedure.
5.2. Ratchet Adjustment
The tool ratchet mechanism features an adjustment
wheel with numbered settings. The adjustment wheel
controls the amount of handle pressure exerted on the
jaws during crimping. If the crimp is not acceptable,
adjust the ratchet as follows:
1. Remove the lockscrew from the ratchet
adjustment wheel. Refer to Figure 4.
2. Using a screwdriver, adjust the ratchet wheel
from the front of the tool.
