Notes on turning the focus knobs

Do not turn (or twist) the right and left focus knobs in opposite
directions at the same time. Doing so may cause malfunction.

When a focus knob reaches its rotational limit for the unit’s
vertical movement, do not forcibly turn it further. Doing so may
cause malfunction.
Do not turn the knobs in opposite directions!

Torque adjustment of the focus knobs
To change the torque of the focus knobs, turn the torque
adjustment ring on the base of the left coarse focus knob
using the tool supplied with the stand. Adjust the torque to an
appropriate level.
The hex driver is fitted on top of each support pillar of the
P-PS32, P-DSL32 or P-DSF32.
Notes on the torque adjustment
When the torque is too low, the zooming body may slide down due
to the various loads it carries, such as its own weight or the load of
the counterbalance spring inside the focus unit. This may result in
injury, such as pinching fingers between the objective and sample,
or cause damage to the sample or objective. Be sure to adjust the
torque to an appropriate level.
Note that turning the fine focus knob will cause the coarse focus
knob to also turn, changing the torque of the fine focus knob.
