Before Use D1 series
1. Notice
⑴As the microscope is a precision instrument, a always
operate it with care, avoiding physical shake during the
operation.
⑵Do not let the microscope emerge in the sun directly, either
not in the high temperature, damp, dusty or acute shake
place. Make sure the worktable is horizontal.
⑶When moving the microscope, you should use both hands to
hold ①and ②as shown on figure, and lay it down
carefully. (Figure 1)
★If hold the focusing knob, eyepiece tube or stage
during moving, you will damage it.
⑷During working, the light condenser will become hot.
Please make sure enough space around ③for
cooling.(Figure 2)
⑸Connect the microscope to earth avoid lightning
strike.
⑹Make sure the power switch ④is on “0” (off) before
replacing the bulb or fuse and wait until the lamp
cools down. (Figure 3
★Bulb: 6V/20W halogen bulb（Philips 7388）
⑺It can adapt wide voltage 90~240V. There is no need
for transformer. Make sure the voltage is in this
range.
⑻Use the special plug supplied by our company.

2．Maintenance
⑴Wipe the lens gently with a soft lens tissue. Carefully wipe off oil or fingerprints on the lens surfaces with
tissue moistened with a little of 3:7 mixture of alcohol and ether or dimethy lbenzene.
★Alcohol and ether is flammable. Don’t place these chemical near to fire or fire source. For example,
when turning on or turning off the electric device, you should use these chemical in a ventilated place.
⑵Don’t use organic solution to wipe the surfaces of the other components. Please use the neutral detergent.
⑶If the microscope damped by the liquid, you should cut off the power immediately and wipe it dry.
⑷Never disassemble or service the microscope yourself. It will influence its function or damage it.
⑸After using, cover the microscope with a dust cover.

2-2 Assemble Steps 2-2-1 Set Condenser (Figure 4/5)
Set condenser for normal illumination
1.Turn the coarse knob with the direction showed to
make the stage to highest position. (Figure 4)
2. Turn the condenser knob with the direction showed
to make the condenser holder down to suitable
position.
3. Loose the lock screw for condenser thoroughly.
4. Slide the condenser into holder with the direction
showed till it is tied with the holder. And turn the
condenser to make the knob direct to front.
5. Tight the lock screw  and use knob  moving the
condenser up to highest position.
Set condenser for Kohler illumination
1.Turn the coarse knob with the direction showed to
make the stage to highest position. (Figure 5)
2. Turn the condenser knob with the direction showed
to make the condenser holder down to suitable
position.
3. Loose the lock screw for condenser thoroughly.
4. Put the screw behind condenser matching with the
slot on condenser holder and slide it into
thoroughly.
5. Tight the lock screw and use knob moving the
condenser up to highest position.
2-2-2 Assemble objectives （Figure 6）
1. Turn the coarse knob ①with the direction showed
to make the stage to suitable position. (Figure 6)
2. Assemble the objectives from low to high
magnification clockwise.
 Please use objective with low magnification
(such as 4X or 10X) to find the image.
Please make sure correct position with a sound
during turning the nosepiece.

2-2-3 Set or replace bulb （Halogen 7）
◎Please use assigned Philips 7388 halogen bulb 6V20W.
 In order to use the bulb longer or prevent blowout,
please do not touch it barehanded. Please swap it
with soft cloth if you leave fingerprint on the bulb.
1. Loose the lock screw ①and turn the bulb holder ②
clockwise.
2. Use gauze or others to take the bulb  and set it into bulb
holder ④.
Please set the bulb softly, over press will damage it.
 Use or replace bulb
During operation or just after using, the bulb and bulb
holder will be very hot. Please turn the switch to “0”
and take off the plug. After the bulb and bulb holder
cool-down, you can replace the bulb.
This microscope is also suitable for LED
illumination, the operation for LED is similar to
halogen bulb.
2-2-4 Set eyepiece （Figure 8）
1. Take off the cap on eyepiece cap ①.
2. Slide the eyepiece ②into eyepiece tube throughly.
2-2-5 Connect plug （Figure 9）
 Do not press the plug too much. Be aware that
bend or enlacement will damage it.
1. Before connect the plug, please turn the switch to
“OFF”.
2. Slide the plug ①into the socket ②on microscope
and make sure good contact. (Figure 9)

slides. (Figure 11)
3. Adjust the knob  to move the slides to center (according
to center of objective).
3-3 Focusing （Figure 12、14、15）
1. Let objective 4X move into light path.
2. Turn one dioptor ring  to make it in line with
reticle  on eyepiece tube. At this time, the
position is “0”. (Figure 14)
3. Turn coarse knob  to find the image. (Figure 12)
4. Adjust anther dioptor to make the image clear.
(Figure 14)
5. Turn fine knob  to make the image clear. (Figure
12) (Suitable for sliding head)
Or
1. Let objective 4X move into light path.
2. Turn one dioptor ring  to make “0” position in
line with reticle  on eyepiece tube. (Figure 15)
3. Turn coarse knob  to find the image. (Figure 12)
4. Adjust anther eyepiece to make the image clear. If
not, please adjust dioptor. (Figure 15)
