Assemble:
1. Important note: remove residues of old Loctite in screw holes with a M3 or M4 tap tool for threads
before assembling the joint to get the correct torque on the new screws.
2. Important note: Always use new pre-coated screws when it is possible. If you have to assemble with
old screws carefully clean the screws and attach Loctite 648 on the screws before assembly.
3. Important note: Always replace the black flexible flat ring to maintain the IP classification.
4. Orientate the joints according to the marks and gently push the two joints together. (In the below
drawing the marks are indicated with red)
5. Gently tighten the 6, 8 or 10 screws, and then tighten in cross order with the correct torque.
See 3.1.5 Torque values

1, 4, 2, 5, 3, 6 and again
1, 4, 2, 5, 3 and 6
