Adjusting the supension system
Adjusting the balance setting of the suspension arm
•
Only perform the balance setting procedure with the complete micro-
scope equipment attached!
Note:
We recommend that you perform coarse balancing of the suspension arm
before starting with precise balance setting of the suspension arm. The
suspension arm must be locked in the horizontal position for this proce-
dure.
•
For coarse balancing, move the suspension arm slightly up and down.
At the same time, turn adjustment screw (2) until you think that the
spring force is sufficient to compensate for the weight of the surgical
microscope and accessories.
Note:
Turning the screw clockwise increases the spring force, turning it
counterclockwise reduces the spring force.
•
Hold the suspension arm and pull out locking knob (1). This must be
possible without major effort. Otherwise, readjust the spring force us-
ing adjustment screw (2).
•
During the balancing procedure, press one of the magnetic brake re-
lease buttons on the surgical microscope. Move the suspension arm
up and down alternately by approx. 20 cm. Use adjustment screw (2)
to adjust the spring force in such a way that the effort required to move
the arm up or down is the same.
