How to use a #3-H Hydraulic Swager


Cable splicing is much easier if the cable is cut clean without frayed ends. We highly recommend  C7, C9, C12 or C16 cable cutters.


Figure 1

TO INSERT A DIE IN THE TOP OF THE HEAD. Push the die release button and place one die of the set in the top of the head, center it and release the button. INSERT THE OTHER DIE IN THE BOTTOM OF THE HEAD. Depress the die release pin and place the other die of the set in the bottom of the head and release the pin. The die will be held by the retainer pin. If it is difficult to depress the die release pin, pump the handle several times, this will expose the pin.

Figure 2

THE HEAD OF THE COMPRESSOR WILL ROTATE 180 DEGREES. The head can be rotated to any desired position to accommodate operator’s view of the dies, fitting position and operation.
CAUTION Do not rotate the head under hydraulic pressure

Figure 3

OPERATE THE PUMP HANDLE until the dies are closed. If the dies are not clearly visible, the pumping should continue until a sound from bypass valve is heard. First Stage, the pumping sound will accompany a reduction in the force required to close the pump handle. After first stage has bypassed, pump 5 to 6 more times until it hits the second stage bypass. If the dies fail to close, it will be due to:
a) the tool being used for some application for which it was not designed.
b) the pressure not building up to 700kgs/cm (10,000 psi)
c) the wrong dies being used for the incorrect size sleeve.

Figure 4

Properly Swaged Sleeve RELEASE PRESSURE AFTER OPERATION. Release pressure by twisting pump handle clockwise while holding the handle in the open position, then move the handle into the closed position.
WARNING: Keep fingers clear from the dies and ram during operation.

Figure 5

Use the gauge that is provided to check the accuracy


  • 1.   Place the tool, head downward, and hold it in a vertical position.
  • 2.   Release pressure by twisting the handle clockwise and press down.
  • 3.   Remove the body handle assembly
  • 4.   Pump the handle several times and release pressure. Repeat this procedure several times. This will clear any air bubbles in the hydraulic system.
  • 5.   Holding the pump handle in the closed position, remove the reservoir cap with care as air bubbles may remain in the end of the oil reservoir.
  • 6.   Fill oil (Shell Tellus oil T15, Mobile DET-13, or equal) and reset the cap.
  • 7.   Check the oil reservoir for pin holes by squeezing reservoir with fingers. If any leaks are detected, replace with a new reservoir


  • 1.   Do not pump the tool to closed jaw position when the dies are not placed in the head. This can place excessive pressure on the jaws resulting in fracture or distortion of the jaws. If the jaws are mistakenly closed without the dies, do not continue to apply pressure by further pumping. If jaws are closed without die, loosen the bypass and the release valve.
  • 2.   Keep the tool clean and free from dirt or metal particles, especially around the head, dies and ram of the tool.
  • 3.   Check the oil level periodically and use clean oil as recommended. Never mix different brands or types of oil as deterioration of the oil seals may result.
  • 4.   Do not adjust bypass cartridge.

* Stainless Steel requires the #0 tool
