Adjusting the balance setting of the suspension arm

G-30-1426-en
Operation
• Now perform the balance setting procedure with the complete micro-
scope equipment attached!
Note:
Before you precisely adjust the balance setting of the suspension arm, we
recommend performing a coarse balance setting of the arm. For this, the
suspension arm must be locked in its horizontal position.
• To perform the coarse balance setting, move the suspension arm
slightly up and down. At the same time, turn the adjustment screw (2)
until you think that the spring force is sufficient to compensate for the
weight of the surgical microscope and accessories.
Note:
Clockwise turning increases the spring force, counterclockwise
turning reduces the spring force.
• Hold the suspension arm and pull out the locking knob (1). This must
be possible without requiring a special effort. Otherwise, re-adjust the
spring force using the adjustment screw (2).
• Press one of the release keys for the magnetic brakes on the micros-
cope during the balance setting procedure. Move the suspension arm
alternately up and down by approx. 20 cm. Using adjustment screw
(2), adjust the spring force in such a way that the effort required to
move the arm up or down is the same in both directions.
