NOTICE
•
Apply one drop of Loctite to the threads (1/Fig. 27).
•
Place the spring washers and the nut back on the threads.
•
First, hand-tighten the nut.
•
Remove the work table from the C-arm and move the C-arm into the vertical position (I.I.
above, SIREPHOS below).
•
Suspend a spring scale from an attachment point on the upper railing and check the
movement force of the angulation movement within an angulation range of approx. +/-
45° from the vertical position.
•
The braking force without the brake applied can be adjusted by tightening or loosening
the nut. When doing this, move the horizontal carriage several times from end stop to
end stop to eliminate the play on the shaft.
