Using the microscope
Using the microscope
ATTENTION: Before any attempt to operate Seiler Evolution Zoom Microscope, please read
carefully and thoroughly the present User’s Guide. This device may only be used by qualied
personnel.
Moving the Unit
The Seiler Evolution Zoom Microscope has been designed to be easily adjusted and handled whilst also
ensuring maximum comfort and stability.
Before using the Seiler Evolution Zoom Microscope, one can move it from one place to another and change
the position of the main modules to meet specic demands, since the followings instructions are considered
(Figure 10 and Figure 11):
To move the microscope with the base to the desired place, release the brakes of the 4 swivel casters. Move
the microscope by the column. After the base is placed on the required place, press the brakes for locking the
wheels.
The level of the base can be set using the Knob to raise or down the swivel casters, so as to place them on a
horizontal plane (Figure 10).
To adjusting the optical system to a specic position, make sure the swivel casters are properly locked (Figure
10). Then, loosen the knobs indicated and place the optics in the required position (Figure 11). After that, re-
tighten the Knobs (do NOT over-tighten them).
It is preferred to place the optical module as near as possible do the column, for improving stabilization.
To rotate the optical module vertically, release knob E. This may be slightly difcult, since the system is
assembled with a preload to prevent the optical module from falling/rotating involuntarily (Figure 2 and Figure 11).
The knob E is set in factory for a specic range of load. When many accessories are assembled, it may be
necessary to increase its preload, adjusting the disc spring washers of the brake mechanism of the knob E
(chapter 8) for greater stiffness. This shall be accomplished according to the following steps (Figure 12):
• Remove the cover indicated.
• Disassemble the screw and the knob E.
• Take apart the disc spring washers 1 and 2.
• Disassemble the body part.
• Apply additional torque to the adjusting nuts in such a way that they increase the preload on the disc spring
washers 3 to 8. Then, low strength thread-locking compound shall be applied to the adjusting nuts to prevent
them from loosing.
• Reassemble all the mechanism, apply low strength thread-locking compound to the screw assembled into the
knob E.

14
ATTENTION: Never use the optical module or the microfocus motor covers as a rest or support to pull, push,
raise or move the equipment. Only use the column or its handle to move the unit.
Figure 10: Swivel casters with brakes
Figure 11: Knob positions of the microscope

15
Figure 12: Brake mechanism of the Optical Module (knob E)
ATTENTION: A spring inside the pantographic arm ensures its smooth and precise movement. The spring’s
tension is NOT pre-set in the factory, because it must be released for transportation. When assembling the
microscope, this spring must be set by its adjustment knob (Figure 11). Where accessories are added to the
optical module, the weight to be balanced by the pantographic arm is increased, so the knob must be turned
anti-clockwise. Become aware of eventual downward movement of the optical system, especially when adding
accessories.
IDEAL SETTING: When moved upwards or downwards, the pantographic arm remains in the new position
without having to tighten the xing Knob of the pantographic arm.
Switching on the Unit
• Connect the AC Power Cable to the Electrical panel and to the grounding electrical socket (Electrical Panel
External Connection).
• Press the Main On/Off Switch at the Control panel (Figure 5).
• Adjust the illumination brightness by turning the button at the Control panel (Figure 5). To control the
illumination level by the multifunctional pedal, press one of the two Illumination On/Off buttons, followed by the
reduction or increase button (Figure 4).
PLEASE NOTE: The illumination source only operates when the multifunctional pedal cable is connected
to its connector (Figure 8).
CAUTION: The multifunctional pedal’s electric circuitry is NOT waterproof. Avoid spilling water directly onto
it. Before cleaning the oor on which the unit is placed, make sure to hang up the pedal in its transport handle at
the column (section 7.6 and Figure 2).

Adjusting diopter
The diopter adjustment aims at adapting the microscope to the user’s eyes, so as to obtain a proper image view
for particular person and work condition. This adjustment allows for both eyes to see focused-way object.
The diopter adjustment can be performed by rotating a ring located below the eyepiece. There is a visible trace to
be used as reference mark during this adjustment. Before carry out any adjustment, verify that zero (0) mark on
the ring coincides with the xed reference trace. It is possible to adjust between –6 and +6 diopters (Figure 13).
Adjusting interpupillary distance
The interpupillary distance adjustment aims at the adaptation of the equipment to the personnel in order
to achieve the best work adjustment. The ideal condition is reached when the user views a single image
(overlapping of eyepieces images).
Models equipped with xed binocular head (optional) can have the interpupillary adjustment made manually at the
boxes that support the eyepieces (Figure 3).
When the microscope comprises inclinable binocular head, interpupillary adjustment can be performed by
releasing a knob (Figure 3).
Adjusting magnification
The Seiler Evolution Zoom Microscope has continuous magnication (zoom).
The continuous zoom magnication system (5x to 30x) is controlled by the multifunction pedal or the joystick
(Figure 4 and Figure 6).
To select the magnication, simply activate the Adjustment Pedal or the Joystick, for increasing or reducing the
zoom. The selected magnication is shown on display.
Adjusting focus
• Center the microfocus system by pressing the centralization button in the upper right side of the control panel
(Figure 5).
• Loosen the knob of the pantographic arm joint (Figure 11), then put the optical module in a distance from the
working that are approximately the focal length of the objective lens in use. Re-tighten the knob to x the
pantographic arm.
• The ne focus adjustment can be performed by pressing the multifunctional pedal or the joystick (Figure 4 and
Figure 6).
• Two red indicator lights on the control panel correspond to downward or upward movement of the microfocus,
so as to indicate the direction of adjustment. When the microfocus reaches its end-limit, a beep is emitted if the
pedal is still pushed down (the indicator light remains lit up in this condition) (Figure 4 and Figure 5).
• For an extra-ne focus adjustment, one may selected the maximum possible magnication of the optical
module, then nd the best possible focus using the microfocus system. This will mean that, for increases to
other controls, the focus will already be at its optimum (section 6.5).
• If required, adjust the diopter or the interpupillary distance (sections 6.3 and 6.4).

Adjusting light level
• Commands for adjusting the light level can be via multifunctional pedal, control panel or joystick (Figure 4,
Figure 5 and Figure 6).
Using the XY system (optional)
This section only applies to microscopes equipped with XY system.
• The XY system can be moved using the foot stick (Figure 4)
• As focus adjustment (section 6.6), light indicators show the movement of XY system and a beep is emitted
when the end-limit is reached (Figure 5).
• To center X and Y axes at the same time, press the center button located at the control panel (Figure 5).
Using the inclinable binocular head
The Inclinable Binocular Head can be inclined manually. In order to do this, incline the ocular lens manually to the
position desired (Figure 3).
Ultraviolet (UV) filter
The Seiler Evolution Zoom Microscope is supplied with conventional lters.
In addition, an anti-ultraviolet (UV) lter is also supplied. They come ready-tted from the factory, screwed into
drum of the lters. Their purpose of it is to prevent the passage of ultraviolet light (the image appears slightly
yellow through the binocular).
To select a specic lter, rotate the drum knob (Figure 14).

Figure 15: Halogen bulb in the illumination box
ATTENTION: Never touch the bulb.
PLEASE NOTE: When reassembling the device, do NOT invert the position of the power sockets. If this
happens, light will be emitted from bulb, but the position of the optical ber inside the illumination box will NOT
match the light bulb in operation. As a result, light will NOT go through the optical ber and, thus, the surgical
eld will NOT be lighted. The correct operation of the equipment must be veried by test immediately after light
bulbs are replaced.
