1. INTRODUCTION
Crimping tools 575937 and 575938 are used to crimp the MATE-N-LOK Terminals listed in the table in
Figure 1. Use this table to select the proper tool for the wire size to be used.
NOTE
Dimensions in this instruction sheet are in millimeters [with inches in brackets]. Figures are for reference only and are not
drawn to scale
Reasons for reissue are provided in Section 5, REVISION SUMMARY.
2. WIRE STRIPPING
Strip the wire 5.2 mm [.200 in.] for both the pin and socket terminals.
3. INSULATION CRIMPING ADJUSTMENT
1. The insulation crimping jaws have three adjustments.
2. Place the insulation crimping adjustment pin in the No. 3 position. See Figure 1.
3. Place the terminal in the tool according to Paragraph 4, and insert the unstripped wire into only the
insulation barrel.
PROPER USE GUIDELINES
Cumulative Trauma Disorders can result from the prolonged use of manually powered hand tools. Hand tools are intended for occasional use and low
volume applications. A wide selection of powered application equipment for extended-use, production operations is available.

4. Crimp the terminal. Bend the wire back and forth once. If the wire pulls out, set pin in No. 2 position
and repeat the test until the desired grip is obtained.
4. CRIMPING PROCEDURE
1. These tools is equipped with a CERTI-CRIMP Ratchet (see Figure 1) to ensure proper crimping. To
open the tool handles, squeeze them until the ratchet releases.
NOTE
Once the ratchet is engaged, the handles cannot be opened until they are fully closed.
2. Place the terminal in the tool so that the locator fits in the slot between the terminal insulation barrel
and the wire barrel. See Figure 2.
Figure 2
3. Close the handles until the crimping jaws close just enough to retain the terminal. See Figure 2.
CAUTION
Do not deform the terminal. Damaged product should not be used. If damaged product is evident, it should be replace with a
new one. Terminals should not be re-terminated.
4. Insert the stripped wire into the terminal until the end of the insulation butts against the locator.
5. Close the tool handles until the CERTI-CRIMP Ratchet releases. Remove the crimped terminal from
the tool.
6. For wire with insulation diameter 3.5 mm [.138 in.] and larger, first insert the wire into the terminal. The
insulation barrel will be fixed around the insulation.
7. Then follow steps 2 and 5.
5. GAGE DIMENSIONS
To ensure the tool is dimensionally correct, check the tool dimensions with a gage. See Figure 3.
