The Light Head/Yoke Assembly or Monitor Cradle is
kept in its position in the Spring Arm by 1 securing
segment. If the securing segment is dismantled, there
is a risk of the Light Head or Monitor sliding out of the
Spring Arm. In this case the Spring Arm suddenly
jumps up and can cause severe injury;
• Before checking the securing segments set the
Spring Arm to its lowermost horizontal (0°) end stop
position.
1. Set the Spring Arm [5] to its lowermost horizontal
(0°) end stop position.
• To do this, dismantle the cover panels from the
Spring Arm and remount them after checking the
securing segments.
2. Check that the Spring Arm is safely locked in place.
Once the Spring Arm has been fixed in its lowermost
horizontal position, it must no longer be possible to
move the Spring Arm upwards.
