Adjusting the system
Balance setting of the suspension arm
Note:
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 up-
ward/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 accesso-
ries. 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 ar-
ea.
Note:
Turning the screw clockwise increases the spring force, turning it counter-
clockwise reduces the spring force.
Setting the limit of downward travel of the suspension arm
Warning!
The downward travel of the suspension arm must be limited in such a way
that the microscope cannot come into contact with the patient even if the
surgical microscope is inadvertently lowered.
•
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.
