Adjusting the system - Ceiling mount, wall mount and S7
Centro suspension system
Setting the suspension arm weight compensation
Do not perform the balance setting until the surgical microscope and all
accessories have been mounted!
• Move the suspension arm into its horizontal position and tightly hold it
with one hand.
• Loosen knob (3) for adjusting the friction of the suspension arm's upward/
downward movement.
• Move the suspension arm slightly up and down. At the same time, turn
adjustment screw (1) until you think that the spring force is sufficient to
compensate for the weight of the surgical microscope and accessories.
Continue to perform this adjustment until the surgical microscope moves
neither upward nor downward. The surgical microscope is fully balanced
when it remains stationary in all positions within the work area.
Rotating clockwise increases the spring force. turning the screw counter-
clockwise reduces the spring force.
Limiting the suspension arm's downward movement
• Loosen locking lever (2) for the upward/downward movement.
CAUTION Risk of crushing - mind your fingers!
Fingers may be crushed in the areas marked with the "Risk of crushing" label.
• Do not touch these areas while the system is being moved or brought in
its working / transport position.
CAUTION Risk of injury caused by lowering of the surgical microscope!
• Limit the stroke of the suspension arm to prevent any contact with the
patient should the surgical microscope be lowered accidentally.
