I have the instructions since I had mine, unfortunately they are in french, but perhaps the pictures could be of assistance.
Here is the translation:
[Left side of page]
Screw 1, screw 2, screw 3.
Regulation of (horizontal) convergence
1: Loosen screw number 1 (key: 1.5mm)
2: Loosen screw number 2 (key: 1.5mm)
3: Work screw number 3 (key: 1.5mm)
- tighten = greater convergence
- loosen = less convergence
(proceed at 1/4 turns maximum each time)
4: Tighten screws numbers 1 and 2 before attempting regulating shot(s)
5: Perform regulating shot(s)
6: If additional regulating is necessary, let barrels cool completely before shooting again (meaning: you can perform steps 1 to 4 even if the barrels are warm, but don't proceed to 5 until they are completely cool)
[Right side of page]
Screws 4, screw 7, screw 6, screw 5
Regulation of (vertical) convergence
1: Loosen the two screws number 4 (key: 0.9mm)
2: Loosen screw number 5 with one turn maximum (key: 2.5mm)
3: Work screw numbers 6 and 7 (key: 1.5mm)
- To lower the point of impact of right barrel (free-floating barrel): tighten first screw number 6, then screw number 7.
- To raise the point of impact of right barrel (free-floating barrel): loosen first screw number 7, then screw number 6.
NB: do not work screws more than 1/4 turn each time
4: Tighten screws number 4 and screw number 5 before attempting regulating shot(s)
5: Perform regulating shot(s)
6: If additional regulating is necessary, let barrels cool completely before shooting again (meaning: you can perform steps 1 to 4 even if the barrels are warm, but don't proceed to 5 until they are completely cool).
I hope this helps. Please let me know if anything is unclear.
Best,
Tom
