3. Hold the terminal in position, and squeeze the tool handles together until ratchet engages sufficiently
to hold the terminal. DO NOT deform the wire barrel.
4. Insert the stripped wire into the wire and holding the wire in place, squeeze the tool handles together
until the ratchet releases. Allow the tool handles to open, and remove the crimped terminal.
5. Inspect the terminal crimp height according to Section 5.
5. CRIMP HEIGHT INSPECTION
This inspection requires the use of calipers. A lead rod can be used to check the crimp height. Crimp a rod in
each of the crimping chambers. Check the crimp height of the rod against the crimp height dimension given in
Figure 4.

If the crimp height conforms to the dimension, the tool and die assembly are considered dimensionally correct.
Lubricate the tool with a thin coat of any good SAE 20 motor oil. If it does not, adjust the crimp height according
to Section 6. If the adjustment does not result in acceptable crimp height, the die assembly or tool may have to
be replaced.
7. RATCHET ADJUSTMENT (Figure 5)
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. Check the crimp height according
to Section 5. If the crimp height is not acceptable, adjust the crimp height as follows:
1. Remove the lockscrew from the ratchet adjustment wheel.
2. With a screwdriver, adjust the ratchet wheel from the front of the tool.
3. Observe the ratchet adjustment wheel. If a tighter (smaller) crimp height is required, rotate the
adjustment wheel counterclockwise to a higher-numbered setting. If a looser (larger) crimp height is
required, rotate the adjustment wheel clockwise to a lower-numbered setting.
4. Re-assemble the lockscrew.
