INTRODUCTION Hydraulic Hand Tool PN 59974-1 is designed for crimping the terminals and splices listed in Figure 1. NOTE Read these instructions thoroughly before using the hand tool. NOTE Dimensions in this instruction sheet are in metric units with U.S. customary units in brackets . Figures and illustrations are for identification only and are not drawn to scale. Reasons for reissue of this instruction sheet are provided in Section 7, REVISION SUMMARY. 2. DESCRIPTION (Figure 1) The hand tool has a stationary lever and a movable lever. These levers are compressed to pump hydraulic fluid behind the ram, moving it forward and thereby closing the dies. After the crimping is complete, the movable lever is turned to depress the plunger, and the moving die retracts to its original position, completing the crimping cycle. 2017 TE Connectivity Ltd. family of companies.

Advance the ram slightly to gain access to the moving die setscrew. Note that the stationary die is held in place by a setscrew. 3. Before inserting the dies, refer to the instruction sheet packaged with the dies for detailed instructions insert or remove dies, as necessary, by following the procedures given in the instruction sheet. 4. CRIMPING PROCEDURE 1. Strip the wires to the dimensions specified in the instructions packaged with the dies (see Figure 1). 2. Insert the terminal or splice in the stationary die in accordance with the instruction sheet packaged with the dies. DANGER Ensure latch pin is fully inserted before operating hand tool. 3. Pump the movable lever until the moving die grips the terminal or splice. CAUTION Do not deform the wire barrel of the terminal or splice. 4. Insert the stripped wire into the wire barrel of the terminal or splice. 5. Continue pumping the moveable lever. There may be a slight audible click indicating that the pump has shifted into the high-pressure stage. Continue pumping the moveable lever. When the dies have bottomed, there will be an audible pop. This indicates that the crimp is complete. CAUTION Potential damage to the tool may occur if the following Step 6 is not taken. 6. Retract movable die by opening the movable handle to the full open position. Turn the movable handle (to actuate striker), DO NOT TURN THE MOVABLE HANDLE WHILE IN THE CLOSED POSITION AS YOU WILL DAMAGE THE PLUNGER (PRESSURE RELEASE), and compress handles to depress plunger (pressure release). Movable die will now retract. 7. Remove the latch pin, open the yoke, and remove the crimped terminal or splice. NOTE If the terminal or splice sticks in the die after crimping, apply a rocking action to remove it from the die. 8. Inspect the crimped terminal or splice in accordance with the inspection procedure in the instruction sheet packaged with the dies. 5. INSPECTION AND MAINTENANCE DANGER Make sure hydraulic pressure is released before following maintenance and inspection procedures, unless otherwise specified in the procedure. It is recommended that an inspection and maintenance program be performed periodically to ensure dependable and uniform terminations. Though recommendations call for at least one inspection per month, frequency of inspection depends on: The care, amount of use, and handling of the hand tool, The presence of abnormal amounts of dust and dirt, The degree of operator skill, and Your own established standards. The hand tool is inspected before being shipped however, it is recommended that the tool be inspected immediately upon arrival at your facility to ensure that the tool has not been damaged during shipment. 2 of 5 Rev G
