2 / 6 page 408-8908 2 of 6 Rev A 1. INTRODUCTION This instruction sheet provides application instructions, maintenance, and inspection procedures for the dies listed in Figure 1. These dies crimp SOLISTRAND Flag Terminals to solid or stranded copper wire (also listed in Figure 1). The dies are used in Hydraulic Head 1490746-1 and Hydraulic Hand Tool 1490749-1. Refer to Figure 1. All dimensions on this document are in metric units [with U. S. customary units in brackets]. Figures are for reference only and are not drawn to scale. 2. DESCRIPTION Each die assembly consists of a nest and an indenter (ordered separately) which are retained in the crimping head by retainer pins. The nest is positioned in the yoke of the crimping head, and the indenter is positioned in the ram of the tool. 3. DIE INSTALLATION AND REMOVAL Refer to Figure 1 and determine the correct die assembly, wire size, product number, and tool head to use with the die assembly. Never operate the tool with the dies removed. 3.1. Die Installation (Figure 2) To avoid personal injury, be sure to exercise extreme caution when using the power unit. Avoid depressing the footswitch or trigger control when installing or removing dies. 1. Depress the upper release button located in the "C"-head. 2. Slide the nest into place in "C"-head. See Figure 2. 3. Release the button and rock the die back and forth until the nest snaps into position. 4. Activate the power unit until the lower die release button located in the ram is exposed. 5. Depress the release button. 6. Slide the indenter into position in the ram. See Figure 2. 7. Release the button and rock the indenter back and forth until the die snaps into position. 8. Return ram to the down position. 3.2. Die Removal (Figure 2) 1. Depress the upper release button located in the "C"-head and slide the nest out of the head. Figure 2 2. Activate the power unit until the lower die release button (located in the ram) is exposed. 3. Depress the release button and slide the indenter out of the ram. 4. WIRE STRIPPING AND CRIMPING PROCEDURE AVOID PERSONAL INJURY. Exercise extreme caution when operating crimping head and holding terminals or wire near the crimping dies. 4.1. Wire Stripping Obtain the correct wire, flag terminal, and crimping tool (with correct die assembly installed) for your application. Strip wire insulation to the dimensions indicated in Figure 3, taking care not to nick or cut conductor(s), and proceed as follows: 4.2. Crimping Procedure 1. Ensure that wire size stamped on flag terminal corresponds to wire size being used in the application and wire size stamped on nest and indenter. 2. Center flag terminal wire barrel in die nest. When crimping flag terminals, hold tongue of flag terminals against nest as shown in Figure 4. If terminal locator is present, slide terminal into terminal locator and press the tongue of the flag terminal against the slope on the nest. 3. Activate power unit so that ram advances and holds terminal in place but DOES NOT deform wire barrel. 4. Insert stripped wire into terminal until end of conductor is flush with or extended slightly beyond end of wire barrel. See Figure 3. 5. Activate power unit to complete crimp. NOTE i CAUTION ! DANGER STOP Nest Die Release Button Indenter Ram (Advanced) DANGER STOP |
