Cleaning of the optical parts
A dust brush is to be employed for dusting the exposed glass
surfaces.
From time to time it is necessary to clean the upper surface of
the condenser. After removing the cover of the lamp housing,
the four exposed knurled screws (132) have to be removed to
lift off the lamp housing unit.
The condenser surface is now visible and can be cleaned with
a brush for cleaning the optics. Surfaces which have become
really dirty should first be dusted, then wiped carefully with a
soft dry clean cloth, washed linen, chamois leather, or some
such material which will not scratch the surface.

B.6
Cleaning of the gliding plate and the rails
If it becomes difficult to move the slit lamp around on the
gliding plate, the plate should be cleaned with a slightly oily
rag.
After removing the rail covers (33), the rails should be cleaned
with a stiff brush.
B.7
Adjustment of friction of the slit width control
The friction of the slit width control (133) can be regulated by
means of the small screw in the centre of the right hand
control. The movement can be stiffened by turning the screw
clockwise or loosened by turning it counter-clockwise. The
screw should be at least tight enough to ensure that the slit
does not close spontaneously.
