5. Insert the scissor arm into the extension arm, aligning the bushing
fixing holes to the extension arm screws. Power cable, signal cable
and grounding cable must be let out freely from the extension arm.
Figure 6-9
6. Mount the friction group and fix the plate using the shorter screw in
the top hole (Figure 6-5). Tighten the grub screw until it is frictioned
but don't force the friction. It has to be adjusted only if necessary.
7. Remove the safety clamp and completely open the scissors arm to
locate the position where the cable is more recovered inside the arm
itself.
