- the branch 126 which is essentially circular comprises a nut 132 which blocks the target 128a.
- the tablet forming the target 128a has a central orifice 134 in the direction of which the water jet J is pointed during the adjustment. Thanks to the perforated structure of the support 122, an operator can, during the adjustment, observe on practically all sides (over approximately 300 °) the impact of the water jet J supplied at low pressure, but in a consistent manner thanks to the socket 26, on target 128a.

- It comprises four converging planar faces 142a to 142d (FIG. 5) inclined at an angle (X d' about 10 ° relative to the direction of exit of the water jet J, and therefore relative to the longitudinal geometric axis of the sighting device 120b.
- the pyramidal pointer 142 On either side of the pyramidal pointer 142 are formed in the base 140 four oblong recesses 144a to 144d oriented parallel to the bases of the pointer 142, as well as in the extension of its four faces 142a to
- These four hollows 144a to 144d respectively have the shape of a flared bowl at the entrance, and they are open towards the water jet J. It will be specified here that the four hollows 144a to 144d are all calibrated to the same dimension.

- the support 122 is inserted into the barrel holder 62 by inserting the adjusting barrel 124 into the bore 64.
- the screws 112 are loosened to allow the barrel holder 62 and the aiming device 120a, 120b to pivot relative to the casing 2, by means of the ball joint 94a, 94b.
- a coherent water jet J thanks to the shape of the conduit 27 of the sleeve 26, forms at the outlet of the adjustment barrel and strikes the target 128a, 128b.
- the sighting device 120a, 120b is then moved manually, by the operator not shown, by rotating the barrel holder 62 relative to the casing 2.
- the gun holder 62 is blocked by means of the screws 112 when the water jet J is placed in coincidence with the orifice 134.
- the operator After having opened the low pressure water supply, moves the pyramidal pointer 142 until its point is perfectly under the water jet J and that four identical water bundles (not shown) form at the outlet of the four calibrated recesses of the base 140, under the aiming device 120b. Any difference in shape in one of the beams at the output of the device indicates to the operator an adjustment error and the direction in which he must move the gun holder 62.
- the adjustment operation completed, the aiming device is released by loosening the clamp 66, then taken out. Then, in the barrel holder 62, the cutting barrel 60 is repositioned, which is now arranged perfectly coaxial with the working jet J.
