All inner and outer burrs must be removed from the cut edge
(ill. 2). Use of the 718R1 Reamer or equivalent is recommended.
Loosen the Cap Screw (ill. 3/5/6) of the Tube Clamp Adapter by
two turns, check, whether the plastic ring has been inserted into
the Tube Clamp Adapter completely and with the chamfer on the
ring's outer diameter first, and then insert the tube 5 mm deep
into the Tube Clamp Adapter while slightly rotating the tube. Next,
place the Tube Clamp Adapter with the tube inserted vertically on
the worktop and fully insert the Tube Adapter into the Adapter until
the tube is in contact with the base rim inside the clamp.
Attention!
The interior surface of the Tube Clamp Adapter and the exterior
surface of the Tube Adapter must be cleaned with 634A3 (Aceton)
in the insertion area prior to final assembly (insertion of the Tube
Adapter into the Tube Clamp Adapter).
For definitive use, the cap screw must be torqued to 5 Nm/3.7
ft. lbs/44 In. lbs with 710D4 Torque Wrench.
Attention!
For reasons of structural strength, the residual pieces of cut tube
adapters must not be used as components in prostheses.
4.2 Adjustment screws (ill. 3/4/5)
Adjustments may be made through adjusting the four 506G3 Adjustment
Set Screws during alignment, fitting and at any time after the prosthesis has
been completed. The optimal position of the components may be preserved
when exchanging parts or when servicing the prosthesis by removing only
the two most deeply set adjacent screws.
Once positioning has been determined, replace any set screws that are too
long (to prevent foam cover damage) or too short (lacking strength).
Screws are available in the following sizes:
