Safety Note
1. Open the box carefully to avoid the accessories, like lens, dropping to ground or being damaged.
2. Do keep the instrument out of direct sunlight, high temperature or humidity, dusty and easy shaking
environment. Make sure the stage is at, horizontal and rm enough.
3. When moving the microscope, carefully carry it with the handle and the base.
4. Make sure the instrument is earthed, to avoid lighting strike.
5. For safety, be sure the main switch is in “O” (off) state and cut off the power supply before replacing
the bulb or the fuse. If you replace the bulb during use or right after use, allow the lamp bulb and the
lamp house to cool completely before touching.
(Designated bulb: 1W S-LED)
6. Check the input voltage: be sure the input voltage which is signed in the back of the microscope is
consistent with the power supply voltage, or it will bring a serious damage to the instrument.
7. Always use the power cord provided by Gima.
8. The electrical equipment of the microscope should be discard as electronic waste.
Maintenance and Care
1. All the lenses have been adjusted properly; do not dismount them by yourself please.
2. The nosepiece and coarse and ne focusing parts are so delicate that it is forbidden to disassemble
them carelessly by yourself.
3. Keep the instrument clean, and do not pollute the optical element when wiping away the dust on the
instrument.
4. The contaminations on the prism, like ngerprints and oil smudges, could be gently wiped with a
piece of soft cloth or tissue paper, gauze which has been immersed in pure alcohol or ether. (Note
that the alcohol and ether are highly ammable, do keep them away from the re 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 solvents to clean the microscope components other than the glass
components. To clean them, use a lint-free, soft cloth slightly moistened with a diluted neutral deter-
gent.
6. When using, if the microscope is splashed by liquid, cut off the power at once, and wipe away the
splash.

7. Do not disassemble any parts of the microscope, as this will affect the function or reduce the perfor-
mance of the microscope.
8. Place the instrument in a cool, dry position. When not using the microscope, keep it covered with a
dust cover. Make sure the lamp socket is cool before covering the microscope.

2.2 Assembly procedure
Installing binocular viewing head (g. 1-2)
Insert the binocular viewing head into the microscope head and turn it to a proper position, then tight it.
g. 1 g. 2
Installing the eyepiece (g. 3-4)
Insert the eyepiece into the eyepiece tube until they are against each other (g. 4).
g. 3 g. 4
Installing the objective (g. 5-6)
1. Adjusting the coarse focus knob until the support device of the mechanical stage reaches its low limit
position.
2. Screw the lowest magnication objective into the nosepiece from the left or the right side, then
revolve the nosepiece clockwise and mount other objectives by the sequence of low to high magni-
cation.
Installing objective this way will make the change of magnication to be easier during using.
• Clean the objective regularly, for lens is susceptible to dust.
• When operating, use 10× magnication objective to search and focus specimen rstly, then replace
with higher magnication objective if necessary.
• When replacing the objective, slowly turn the nosepiece until you hear “clicked”, that means the ob-
jective is in place.

Connecting the Power Cord (g. 7-9)
The cable and cords are vulnerable when bent or twisted, never subject the power cord to ex-
cessive force.
1. Set the main switch 1 to “0” (off) state before connecting the power cord.
2. Insert the plugs 2into the power jack 3of the microscope safely.
3. Plug the power cord 4into the power supply receptacle 5. Make sure the connection is well.
• Do use the supplied power cord all the time. If lost or damaged, select the same standard cord,
please.
• A wide range of voltage, like 100V~240V, is acceptable for this microscope.
g. 7 g. 8
Replacing the fuse (g. 8-9)
Do remember to set the main switch 1to the
state “0” (OFF) and unplug the power cord be-
fore replacing the fuse. Rotate the fuse out of the
holder 3, replace with a new fuse, then rotate it
back to the holder again.

3.2 Adjustment and Operation
Brightness Adjustment (g. 12-13)
1. Connect the power cord and set the main switch 1to “ – ”state (ON).
2. Turning the brightness adjustment knob 2.
g. 12 g. 13
Placing the Specimen (g. 14)
1. Place the specimen the center of the mechanical stage and use the stage clips to clamp it.
2. Turn the portrait and lateral adjustment knob 1 of the mechanical ruler, move the specimen to the
required position.
• Be careful when changing the objective. If you nish the observation with the short working distance
objective, and want to change another one, becareful of not letting the objective touch the specimen.
g. 14 g. 15
Focusing the Specimen (g. 15)
1. Focus the specimen with 10x objective. To avoid the objective touching the specimen during focus-
ing, you should raise the mechanical stage to let the specimen close to the objective at rst, then
slowly separate them to bring the specimen to focus.
Turn the coarse focus knob 1conversely to lower the specimen and search images in the 10×ocular
simultaneously, and then use the ne knob 2to focus. After that, you can replace with other magni-
cation objectives safely, and focus without the risk of damaging the specimen.
• To make the observation more convenient, you can use the locking set 3to x the stage in a vertical
direction.

Condenser Adjustment (g. 16)
Turn the condenser focus knob 1to move the
condenser up and down. Raise the condenser
when using the high magnication objective,
and descend it when using the low magnica-
tion one.
1. Focus the specimen with 10x objective.
2. Adjust the condenser focus knob 1to get a
clear image of the eld iris diaphragm.
3. Turn the condenser centering knobs 2to
center the image of eld iris diaphragm in the
eld of view.
• The condenser and the objective are coaxial.
It has been adjusted before leaving factory, so
the user needn’t to adjust them by self
• The highest position of the condenser has
been adjusted too. It also needn’t any user’s
operation. (The top surface of the condenser
is 0.03 mm - 0.4 mm lower than the stage top
surface.)
Aperture Iris Diaphragm Adjustment (g. 17)
Turn the aperture iris diaphragm stick 1to adjust
the aperture iris diaphragm.
• The aperture iris diaphragm is designed for
the adjustment of the numerical aperture, not
for the brightness.
Generally, setting the aperture iris diaphragm
to 70- 80% of the N.A. of the objective in use
will provide an image with good contrast. If
you want to observe the image of the aperture
iris diaphragm, remove one eyepiece and look
through the tube. You will see a dark circle en-
croaching on the bottom of the tube.
Adjusting the Interpupillary Distance
(g. 18)
The interpupillary distance range: 47mm-78mm
While looking through the eyepieces, move both
eyepieces round until the left and right elds of
view coincide completely.

Adjusting the Diopter (g. 19)
1. Turn the eyepiece 1to adjust the diopter while
looking through it.
• The diopter range of the eyepiece is ±5 di-
opter. The number aligned to the line on the
viewing head is the diopter in use.
Adjusting the tension adjustment collar (g.
20)
Turn the tension adjustment collar 1with your
ngers. When the collar is turned in the direction
of the arrow, the tension of the coarse adjust-
ment knob 2increases. Turning the collar in the
opposite direction decreases the tension.
If the nosepiece descends on its own or if the
specimen gets out of focus quickly even when it
is brought into focus using the ne adjustment
knob 3, it means the tension of the coarse ad-
justment knob is too low. Turn the collar in the
direction of the arrow to increase the tension.
