1. A microscope is a precision instrument with delicate glass components, please handle with care
2. Do not use the microscope where it is subjected to direct sunlight, high temperature, humidity, dust and
vibrations.
3. The microscope is ventilated by natural convection. Be sure to leave enough space (10 cm or more) around
body when installing the unit.
4. Arm handle is provided for carrying the microscope.
To prevent damage, do not hold the microscope by the stage or observation tube. Be sure to remove the specimen
from the stage clip while transporting unit to avoid damage to the specimen slide.

SAFETY INFORMATION

Lx POL
if the microscope is used in a manner not specified by this manual, the safety of the user may not be warranted. In
addition, the equipment may also suffer damage. Always use the equipments as outlined in this instruction manual.
I) General Cleaning
Your Microscope has been engineered for a long and safe operational life with the least amount of maintenance
required. In general, routine maintenance is limited to keeping the microscope working parts lubricated and optics
clean.
Clean all glass components by wiping gently with cleaning cloth provided. To remove fingerprints or oil
smudges, wipe with cleaning cloth slightly moistened with a mixture of petroleum (85%) and isopropanol
(15%)
Since solvents such as petroleum and isopropanol are highly flammable, they must be handled carefully. Be
sure to keep these chemicals away from open flames or potential sources of electrical sparks - for example,
electrical equipment that is being switched “ON” or “OFF”. Also remember to always use these chemicals
only in a well-ventilated room.
Do not attempt to use organic solvents to clean the microscope components other than the glass
components. To clean non-glass components, use a lint-free, soft cloth slightly moistened with a diluted
neutral detergent.

Maintenance and Care
3. Do not disassemble any part of the microscope as this could result in malfunction or mitigated performance.
4. When not using the microscope, ensure that the frame is fully cooled before storing the unit in a dry locker or
covering with a dust cover (provided).
5. To clean the Flip Top Condenser, fully loosen the securing thumb screw (1) and remove the condenser then, wipe
the front lens of the condenser with optical cleaning solution (mixture suggested above) and lens tissue.
The Flip Top Abbe can be re-attached in its seat, by tightening securing thumb screw, and raising condenser
bracket to desired position. (As shown in picture)
6. Be sure to observe you local rules / regulations for product disposal.
7. Always cover the Microscope with the provided dust cover when not in use
II) Optical Cleaning
1. The objectives have been adjusted for a tight fit to prevent any damage during transportation. To remove an
objective, rotate it counterclockwise while gripping it with a rubber sheet, etc. to avoid any slippage.
2. To clean the lens surfaces, remove dust using a soft brush or compressed air (cans available at your local electronic
store). For removing finger marks or grease, soft cleaning cloth or lens tissue lightly moistened wit cleaning solution
(85% petroleum ether and 15% isopropanol) should be used. For cleaning the objective optics, use Meathanol.
Observe sufficient caution in handing Methanol. Place the Objectives and / or eyepieces on a dust free surface (e.g.
aluminium foil). All other optical components to be cleaned should be as accessible as possible.
3. Blow all loose dust particles away with compressed air of mini dust blower.
4. Remove all water-soluble dirt with distilled water. If this is unsuccessful repeat using a solution of diluted hand soap
liquid. Remove any remaining residue with a dry cotton slab.
5. To remove oil, use a solution of diluted hand-soap liquid initially. If this does not produce a satisfactory result, repeat
the cleaning using a solvent (Optical Cleaning Solution 85% petroleum ether and 15% isopropanol).
6. Grease must always be removed using a solvent.
7. Cleaning is achieved by using a spiral motion from the center to the rim. Never wipe using zig-zag movements as
this will only spread the dirt. With larger optical surfaces (e.g. tube lenses) the spiral motion starts initially at the rim
before moving to the middle and is then followed by a center to rim cleaning motion. Normally several spiral wipes
are recommended.
We recommend pure, volatile petroleum ether or Optical Cleaning Solution as explained in point 3 above.
Wipe using a spiral movement Donot use a zig-zag motion
III) Cleaning of Painted Surfaces
Avoid the use of any organic solvent (e.g. thinner, xylene, ether, alcohol etc.) for cleaning of painted surfaces of the
instrument. Painted surfaces can be cleaned with a very lightly moistened micro fiber cloth. Loose dust and other dirt
particles can be removed using a soft bristle brush used exclusively for this purpose.

This microscope has an ergonomic design that ensures minimum exertion of the user. However, some of the
risks that the user should keep in mind are:
i) Risk of Infection:
After the microscope has been used for observation of a specimen containing bacteria, clean all parts coming in
contact with the specimen to prevent infection.
1. Be sure to remove the specimen before moving this product.
2. In case the specimen is damaged by erroneous operation, it is important to clean all surfaces that may
come in contact with the specimen.
ii) Electrical Hazards:
To avoid potential electrical hazards when replacing halogen bulb turn the microscope’s main switch to the OFF
position and disconnect power cord from wall outlet in advance. Whenever you replace your microscope bulb,
allow lamp socket and bulb to cool before touching.
I) General Instructions:
1. Install microscope on a sturdy, level table or bench and aovid any restriction of air vents in the base of the
unit. Do not place microscope on a flexible surface as this could result in blocking the air vents and cause
overheating.
2. Always use the power cord provided by LABOMED. If the proper power cord is not used, product safety
performance cannot be warranted.
3. When installing the Microscope, route the power cord away from the microscope frame, Should the power
cord come in contact with the Microscope base, the power cord could melt due to overexposure heat.
4. Always ensure that the grounding terminal of the Microscope and that of the wall outlet are properly
connected. If the unit is not grounded. LABOMED can not warrant electrical safety.
5. Never allow metallic objects to penetrate the air vents of the Microscope frame as this could result in user
injury and damage to the Microscope.
6. After operation of Microscope, be sure to disconnect power cord from connector socket of the Microscope
or from the wall power outlet.

1. Before attaching the lamp bulb, remove the parts that may drop
such as the filter and specimen from the Microscope frame, and
place the Microscope on its back so that the bottom plate is
exposed.
2. Pull the lock know (1) on the bottom to open lamp housing door
(fig. 1)
3. Hold the halogen bulb (2) without taking it out of the polyethylene
bag so as not to taint the bulb with fingerprints and push the bulb
into the pin holes on the socket (3). After attaching, remove the
polyethylene bag.
4. With the lock knob pulled out, close the lamp housing door, then
push the lock knob back to lock the cover. Always use the
designated bulb. Using a bulb other than those specified by
LABOMED may lead to a fire hazard. Fingerprints or stains on the
lamp bulb reduce its life. If contamination occurs, wipe bulb
surface with a cloth slightly moistened with alchohol.
Applicable Bulb: 6V20W Halogen Bulb P/N CX-013

Caution: For Fuse replacement
Set the main switch to “O” (OFF), disconnect the power cord from the
wall outlet.
Before replacing the fuse, remove the parts that may drop such as the filter
and specimen from the microscope frame. Turn around the microscope to
its back so that the AC inlet is visible.
1. Use a flat head screw driver to open the fuse holder (1).
2. The fuse tray will come out with (2) live fuse and (3) spare fuse. Do
not pull out the fuse tray with force as it is locked and will not be out
completely.
3. Replace the primary fuse (2) with the spare fuse.
4. Engage the fuse tray back in.
Always use the designated Fuse. Using a fuse other than those
specified by LABOMED may lead to a fire hazard.
