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 may be available. figure 1 1. introduction straight action hand tool cat-ht-246-1416-14 (figure 1) was designed to crimp cc46r and cc46l series contacts for the mpss and mpcc series. the wire crimper bottoms against the anvil before the ratchet releases. this is a design feature that assures maximum electrical and tensile performance of the crimp. do not re- adjust the ratchet. dimensions in these instructions are in metric units [with inches in brackets]. figures are for reference only and are not drawn to scale. for recalibrations, or locator replacements please con - tact samtec application tooling group. 2. description the front of the tool is marked with the tool part number. the tool features a fxed die (crimper), a movable die (an - vil), a locator wire stop, and a ratchet. the locator positions the contact and the wire stop limits the insertion distance of the stripped wire into the contact. the ratchet assures full crimping of the contact. once engaged, the ratchet will not release until the dies have been fully closed. 3. crimping procedure do not cut or nick the wire strands during wire stripping. damaged contacts should not be used. if a damaged contact is evident, it should be cut from the wire and replaced with a new one. 1. select the desired terminal listed in the figure 3. 2. load the terminal into the proper nest opening marked with the wire gauge on the hand tool. see figure 2. 3. close the tool handle until the frst ratchet position en - gages. 4. insert the properly stripped wire through the terminal and against the wire stop. see figure 2. 5. crimp the terminal by squeezing the tool handles until the ratchet mechanism cycle has been completed. release the handles to open the jaws. 6. remove the crimped terminal from the locator by lifting up and then pulling the wire out. 7. visually inspect the crimped terminal for proper crimp location. figure 2 straight action hand tool cat-ht-246-1416-14 instruction sheet STS-M-246-1416-14 rev a 27 jan 16 customer service +1-800-726-8329 (+1-812-944-6733) 1 of 3

4.2. crimp height inspection this inspection requires the use of micrometer with a modi - fed anvil as shown in figure 5. proceed as follows: 1. select a contact and wire (maximum size) for each crimp section. 2. refer to section 3 and crimp the contact(s). 3. using a crimp height comparator, measure wire barrel crimp as shown in figure 5. if the crimp height conforms to applicable specifcations, the tool is considered dimension - ally correct. figure 5 4.3 miscrimps or jams should this tool ever become stuck or jammed in a partially closed position, do not force the handles open or closed. the tool will open easily by pressing up on the ratchet re - lease lever in the movable handle. see figure 6. figure 6 5. tool dimensions refer to figure 7 for tool dimensions customer service +1-800-726-8329 (+1-812-944-6733) 3 of 3 figure 7 straight action hand tool cat-ht-246-1416-14 STS-M-246-1416-14
