III. Assembling the microscope
The components for the S41-20 microscope are shipped detached for protection. Open
the styrofoam packing with care and do not leave any components attached to the
packing being removed. Do not discard any of the packing materials until all of the
components have been identified. Remove the plastic covers from the microscope's
head and the two gooseneck LED lights.
Assemble the stand connector and its supporting pillar on the vertical pillar, tightening
the fastening knobs. Attach the working arm to the stand connector, the focus block
connector to the microscope head, and then connect the working arm and focus block
connector via the focus block fixing knob.
Locate the power cord, attach it to the microscope, and then plug it in. Turn on the
power switch found on the back of the microscope stand.

IV. Using the microscope
Interpupillary adjustment
Adjust the two eyepiece tubes until only one circular field can be seen through the two
eyepieces. If two separate circles appear, the interpupillary distance is too large; if two
overlapping circles appear, the interpupillary distance is too small. The eyepiece tube
allows a flexible adjustment of the interpupillary distance between 54 and 76mm.
Focusing the microscope
To focus the sample, use the focusing knobs located on both sides of the head holder.
By turning these knobs, the microscope can be moved up or down a certain distance.
This movement is enabled by a “rack and pinion” mechanism.
Using the focusing knob, focus the sample until the image is clear. If the sample cannot
be brought into focus within the travel range of the S303/S304 pole arm and stand,
adjust the microscope head height along the vertical pillar to a working distance of
230mm from the sample. Remember to tighten the locking screw and support collar
after adjusting the height of the microscope.
Magnification and working distance
Change the optional eyepieces to increase or decrease magnification range.
Total magnification used can be calculated by multiplying the eyepiece magnification by
the objective lens magnification.
Increasing the working surface
The two gooseneck lights on this S41-20 microscope are flexible and can be directed in
many directions as needed to maximize the surface area covered by the microscope.
Likewise, the working arm can swing a full 360°to cover larger surface areas.
Adjusting the tension of focusing knob
A spanner is included in the packaging of SL41-20 for the focusing knob tension
adjustment. If necessary, use the spanner to adjust the tension.

V. Maintenance and repair
Cleaning
Keep all lenses clean. Fine dust on the surface of the lens should be gently blown off
with an air canister or wiped off with a soft lens cloth or lens tissue. Stubborn fingerprint
smudges or oil marks can be wiped off with lens tissue moistened with a small amount
of xylene or a 3:7 mixture of alcohol and ether. Never use organic solutions to clean any
other surface (especially the plastic surfaces). If necessary, please choose a mild
detergent.
Storage
After use, cover the microscope with the dust cover provided and store it in a dry and
clean place free from moisture to prevent rust. Remove the eyepieces when not in use,
and place covers on the eyepiece holders.
Repair
Do not attempt repairs on your own, particularly on the optical parts. Contact a Swift
Optical representative through our customer service email or phone line with any
issues.
VI. Troubleshooting
If you have a problem, you may be able to correct it yourself. Here are some common
issues and easy solutions you can try before calling customer support for service.
*Caution: Never disassemble the electrical, mechanical, or optical components. This
servicing should only be done by a Swift technician.
