Balance setting of the suspension arm
Do not perform the balance setting until the surgical microscope and all ac-
cessories 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.
Setting the limit of downward travel of the suspension arm
• Loosen locking lever (2) for the upward/downward movement.
• Lower the surgical microscope until it can be focused on the surgical field
(depending on the focal length of the objective lens), while at the same
time allowing for a sufficient safety distance from the surgical field.
• Firmly retighten locking lever (2) for the upward/downward movement.
• Lower the surgical microscope again to the lowest limit stop and check
the safety distance.
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
into its working / transport position.
CAUTION Risk of injury caused by lowering of the surgical microscope!
• Always limit the downward travel of the suspension arm to prevent any
contact with the patient in case the surgical microscope is lowered acci-
dentally.
