. Safety Notes
Ⅰ
1.Carefully open the box, a oid the accessories, like lens, dropping to ground and being
damaged.
2.Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy
shaking en ironment. Make sure the stage is smooth, horizontal and firm enough.
3.When mo ing the instrument, please use two hands to grip with the two sides of the
microscope body.
4.When running, the lamp house and nearby parts will be ery hot. Please ensure there is
enough cooling room for them.
5.Make sure the instrument is earthed, to a oid lighting strike.
6.For safety, be sure the main switch is in “O”(off) state before replacing the halogen lamp or
the fuse, then cut off the power, and do the operation after the lamp bulb and the lamp house
completely cool down.( Specified: Halogen Lamp 6V/20W or LED 3W)
7.Check the input oltage: be sure the input oltage which signed in the back of the
microscope is consistent with the power supply oltage, or it will bring a serious damage to
the instrument.
8.Use the factory supplied power cord, please.
II. Maintenance
1.All the lenses ha e been well checked and adjusted. It is forbidden to disassemble them
yourself.
2.The nosepiece and coarse/fine focus unit ha e a compact and precise frame; please don’t
disassemble them as possibly as you can.
3.Keep the instrument clean, wipe dust regularly, and be attention to a oid contaminating the
optical elements especially.
4.The contaminations on the prism, as finger mark and oil, could be gently wiped with a piece
of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or aether. (Note
that the alcohol and ether are highly flammable, do keep them away from the fire or potential
sources of electrical sparks, and use them in a drafty room as possible as you can.)
5.Do not attempt to use organic sol ents to clean the microscope components other than the
glass components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted
4
neutral detergent.
6.When using, if the microscope is splashed by liquid, cut off the power at once, and wipe up
the moisture.
7.Do not disassemble any parts of the microscope, which will affect the function or decline the
performance of the microscope.
8.Place the instrument in a cool, dry position. When not using the microscope, keep it co ered
with a dust co er. Make sure the lamp socket is cool before co ering the microscope.

Before installing, be sure e ery components is clean, do not score any parts or glass
surface.
Keep well with hexagon wrench pro ided. When replacing the components, you will need
it again.

1. Adjusting the coarse focus knob until the support de ice of the mechanical stage reaches
its low limit position.
2. Screw the lowest magnification objecti e into the nosepiece from the left or the right side,
then re ol e the nosepiece clockwise and mount other objecti es by the sequence of low to
high magnification
Installing objecti e this way will make the change of magnification to be easier during
using.
Clean the objecti es regularly, for lens is susceptible to dust.
When operating, use 10×magnification objecti e to search and focus specimen firstly, then
replace with higher magnification objecti e if necessary.
When replacing the objecti e, slowly turn the nosepiece until you hear “clicked”, which
means the objecti e is in the required position—center of the light path.

There are two types of illuminator a ailable for this microscope, one type is halogen lamp
6V20W, the other is 3W LED.
During use or just after using, the lamp house and nearby parts will be ery hot. Please set
the main switch to “O” (off) state before replacing, and make sure the bulb, the lamp room
and periphery areall cool enough to carry no burn. Then, you can do your replacing.
1. Loose the bolt and open the window on the bottom of the microscope base with

2. Pull out the old bulb ,hold the new bulb after you wrap it with gauze or other protection

materials and insert its pin as deeply as possible into the jack in the lamp holder.
3. Close the window and tighten the bolt .
①
Please insert the bulb gently, or it will be damaged by excessi e extrusion.
Do not touch the halogen bulb with bare hands. It will shorten the ser ice life or cause it to
burst. If you lea e fingerprints on the surface carelessly, clean it with a piece of dry soft cloth.
When replacing LED ：
1. Generally, the LED has long ser ice life and is not easy to damage, if unfortunately it
damaged, purchase a new one from the supplier.
2. Remo e the base plate from the bottom side of the microscope base with screw

1. Focus the specimen with 10X objecti e. To a oid the objecti e touching the specimen
during focusing, you should raise the mechanical stage to let the specimen close to the

2. Turn the coarse focus knob con ersely to lower the specimen and search images in the

replace with other magnification objecti es safely, and focus without the risk of damaging the
specimen.
●The tight tension of the coarse focus knob has already been adjusted before lea ing

Turn the condenser focus knob to mo e the condenser up and down. Raise the condenser
when using the high magnification objecti e, and descend it when using the low magnification
one.
The condenser and the objecti e are coaxial. It has been adjusted well before lea ing
factory, so the user needn’t to adjust them by self (the distance between the top of the
condenser and the stage should be in the range of 0.03mm~0.4mm.)
The highest position of the condenser has been adjusted too. It also needn’t any user’s
operation.
