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. Figure 1 1. INTRODUCTION This instruction sheet describes the use of Extraction/ Lance Reset Tools 843477-[ ] and 843996-2, -3, -4, and -5. These tools are designed to remove MTE*, Mod IV, Tandem Spring, and Mini Tandem Spring contacts from housings and reset the overly depressed contact locking lances of the removed contact (see Figure 1). The two tool types are basically the same except for the lance reset angles. The reset angle of tool 843477-[ ] is 21° and the reset angle of tool 843996-2, -3, -4, and -5 is 17°. This is to accommodate the different designs of the locking lances of Mod IV, Mod IV.v, Mod V contacts, as shown in Figure 1 and Figure 2. The 843477-[ ] tools are used with contacts having the old style locking lance design and 843996-2, -3, -4, and -5 tools are used with the contacts with the new style locking lance design. Read these instructions thoroughly before attempting to remove any contacts or resetting the locking lances. All dimensions are in millimeters [followed by inches in brackets]. Figures and illustrations are for reference only and are not drawn to scale.

  1. Repeat Steps 1 through 4 for AMPMODU MTE housings when contact reaches preload window (see Figure 2). 3.2. Extraction Tools 843477-5 and 843996-5 (Figure 3, View B) Tools 843477-5 and 843996-5 release the locking lance from the side of the housing cavity. The edge of the locking lance will be visible in housings requiring this tool. Proceed as follows: 1. Align tool so that wide part of tip is oriented with long part of lance cavity, and tip taper is opposite locking lance. 2. Insert tool tip between locking lance and housing until the tool stop bottoms. 3. Pull back lightly on the wire and, if necessary, move tool just enough to release the lance. 4. Remove the contact from the housing; then remove the tool. 4. LOCKING LANCE RESET PROCEDURE (FIgure 3, View C) The tools described on this sheet are designed to reposition depressed locking lances to ensure retention in the housing. Check compatibility of the contact and tool; then proceed as follows: 1. Orient the reset tip so the taper is facing the locking lance. 2. Keep the reset tip flat against the receptacle box and slide it toward the base of the locking lance until it bottoms. 3. Remove tool tip and contact will be ready for re- insertion into the housing. Damaged product should not be used. If a damaged contact is evident, it should be cut from the wire and replaced with a new one. If a damaged housing is evident, it should be replaced. 5. TOOL INSPECTION/MAINTENANCE Tools 843477-[ ] and 843996-[ ] should conform to the dimensions listed in Figure 4. It is recommended that each tool be inspected upon its arrival to be sure it has not been damaged in transit and at regularly scheduled intervals to be sure it remains functional. 6.
