Balancing the surgical microscope
Warning!
Balance the completely equipped surgical microscope before surgery
without the patient.
To permit almost effortless guidance of the surgical microscope, the sur-
gical microscope and the suspension system used must be correctly bal-
anced. If the system is in an extremely unbalanced state, the unit can
move uncontrollably out of position. For this reason, hold the surgical mi-
croscope tightly at its handgrips before releasing the magnetic brakes.
Note:
To set the balance of the microscope's axis of rotation, the lateral and
front-to-back tilt axes and to adjust the friction of the axis of rotation, press
the magnetic brake release button on one of the handgrips.
When adjusting balancing knobs (2 and 3), carefully turn them in either
direction shown on the labels. To avoid damaging the balancing system,
do not use force by turning the knobs too far.
•
Turn on the instrument at the power switch of the suspension system.
Adjusting the friction of the axis of rotation
•
Use knob (1) to adjust the friction of the microscope's axis of rotation
as required.
Balancing the front-to-back tilt motion
•
Use knob (2) to adjust the spring force in such a way that the surgical
microscope is balanced about its front-to-back tilt axis and remains
stationary in the viewing direction required.
Balancing the lateral tilt motion
•
Use knob (3) to adjust the spring force in such a way that the surgical
microscope is balanced about its lateral tilt axis and remains station-
ary in the viewing direction required.
