 NOTE : If you swage with the tool series D12000, refer to the farther
____
 step.

 (a)
 Push the die block assembly out of the head assembly.

 (b)
 Make sure that the upper and lower dies have the same serial number.

 (c)
 Put the lower die block on the top of the power unit.

 (d)
 Connect the power unit to the hydraulic pump.

 (e)
 Put the head assembly on the fitting and the hydraulic tube. Make sure that the bevelled end of the die is towards the center of the fitting.

 (f)
 Put the knurled surface of the power unit and of the head assembly on the same side and engage the power unit on the head assembly. Make sure that the balls in the lower die block engage with a "click" on the head assembly.

 (g)
 Move the power unit toward the center of the fitting until the stop plate touches the fitting.

 (h)
 Make sure that the end of the fitting is on the reference mark. (Ref. Fig. 217/TASK 20-23-11-991-008)

 (i)
 Apply a hydraulic pressure of 690 +17 -17 bar (10007.6013 +246.5640 -246.5640 psi) to the power unit in order to swage the fitting.

 (j)
 Release the pressure.

 (k)
 Remove the power unit and the head assembly.

 (5) Swage with the tool series 12000 CAUTION : MAKE SURE THAT ONLY APPROVED PERSONNEL USE THIS TOOL. THIS
_______ TOOL OPERATES AT VERY HIGH PRESSURE AND CAN BE DANGEROUS.
 (Ref. Fig. 220/TASK 20-23-11-991-010)

 (b)
 Move the yoke into position on top of the fitting:

 -
the silver side of the yoke assembly must be nearest to the end of the fitting that you must swage,

 -
the silver side of the yoke must be aligned with the end of the fitting. Push the die holder into the yoke assembly:

 -
the silver faces of the die holder assembly and the yoke must be on the same side,

 -
the silver sides of the yoke and the die holder must be aligned with the end of the fitting.

 (c)
 Install the power unit:

 -install the square connector of the power unit in the swage head assembly,
 -tighten the knurled nut of the power unit with your hand,
 -connect the hose and coupling half-assembly of the hydraulic power supply (D12025-001) to the nipple valve of the power unit.
 Make sure that:
 -the end of the fitting is above the area of the insertion mark on the tube, (Ref. Fig. 217/TASK 20-23-11-991-008)
