Changing the direction of force
The following description assumes that the joint is delivered ex-factory and therefore the tension spring
has been assembled with the red side facing up. Make sure the joint faces with the logo readable in front
of you, is in the neutral position (0°) as to minimize spring force, and the joint is unlocked (Fig. 1).
Step 1
Loosen the central screw on the housing using the allen screwdriver. Remove the screw and the
underlying retainer ring (Fig. 2).
Step 2
Lift the housing over the central axis and lay it aside. Now the entire power indicator disc with the
red indicator and circles is visible. Lift this also from the axis and lay it aside safely. Using your
fingers, move the spring up over the central joint axis and remove it (Fig. 3).
Step 3
Now turn the spring around its axis with the yellow side facing upward, flex the joint 90° allowing you
to replace the spring over the central axis. CAUTION: Make sure the spring is placed correctly
between the recess of the central axis (Fig. 4).
Step 4
Using a cloth, wipe the power indicator disk clean and place it – but now with the yellow indicator
and circles facing upward – back over the central axis. CAUTION: The tail of the spring should be
positioned in the distal recess of the joint (Fig. 5).
Step 5
Place the housing and retainer ring back correctly and screw them back onto the joint (Fig 6).
Aligning the joint
In order for the joints to function correctly, it is important they are aligned correctly to one another,
and a construction with sufficient torsion rigidity is built by using the free motion joint or R.O.M. joint.
Make sure to take the necessary precautions, or use the alignment device (Art. Nr. MM-950).
