1 Before use
1.1 General notes
You must open the packaging carefully, to make sure that none of the accessories in
the packaging fall on the floor and get broken.
In general, microscopes should always be handled carefully because they are
sensitive precision instruments. When using or transporting the microscope it is
particularly important to avoid abrupt movements, as this may damage the optical
components.
You should also avoid getting dirt or finger prints on the lens surface, because in
most cases this will reduce image clarity.
To maintain the performance of the microscope, it must never be disassembled. So
components such as lenses and other optical elements should be left as they were
before use. Also the electrical parts in the base of the device must not be tampered
with, as in this area there is an additional risk of triggering an electric shock.
1.2 Notes on the electrical system
(OSF 523, OSF 525, OSF 527)
Before connecting to a mains power supply, you must make sure that you are using
the correct input voltage. The information to select the correct mains cable is located
on each device, on the rear of the product directly above the connection socket. You
must comply with this information. If you do not comply with these specifications, then
fires or other damage to the device could occur.
The main switch must also be switched off before the mains cable is connected. In
this way you will avoid triggering an electric shock.
If you are using an extension cable, then the mains cable you use must be earthed.
If the original fuse should blow, it must only be replaced by an appropriate fuse.
Suitable replacement fuses are included with the delivery.
When carrying out any procedures whereby you come into contact with the electrical
system of the device, such as, for example, changing the bulb or fuse, only carry out
these procedures when the power is disconnected.

1.3 Storage
You should ensure that the device is not exposed to direct sunlight, temperatures
which are too high or too low, vibrations, dust or a high level of humidity.
The ideal temperature range is between 0 and 40°C and a relative humidity of 85%
should not be exceeded.
The device should always be located on a rigid, smooth, horizontal surface.
For devices with pillar stands, the microscope holder must not be rotated back too
far. If you do this, there is a risk that the microscope could tip over.
When the microscope is not being used, you should fit the objective cap and cover
the microscope with the enclosed dust protective cover.
If the eyepieces are being stored separately, the protective caps must be fitted to the
tube connectors. In most cases, if dust and dirt gets inside the optical unit of a
microscope this can cause irreversible errors or damage.
The best way to store accessories which consist of optical elements, such as, for
example, eyepieces and objectives, is in a dry box with desiccant.

1.4 Maintenance and cleaning
In any event, the device must be kept clean and dusted regularly.
If any moisture should be occur, before you wipe down the device you must ensure
that the mains power is switched off (if lighting unit is fitted).
When glass components become dirty, the best way to clean them is to wipe them
gently with a lint-free cloth.
To wipe oil stains or finger prints off the lens surface, moisten the lint free cloth with a
mixture of ether and alcohol (70 / 30 ratio) and use this to clean the lens.
You must be careful when handling ether and alcohol, as these are highly flammable
substances. You must therefore keep it away from naked flames and electrical
devices which can be switched on and off, and only use it in well-ventilated rooms.
However organic solutions of this type should not be used to clean other components
of the device. This could lead to damage to the paint finish. To do this, it is sufficient
to use a neutral cleaning product.
You could also use the following cleaning products to clean the optical components:
Special cleaner for optical lenses
Special optical cleaning cloths
Bellows
Brush
When handled correctly and checked regularly, the microscope should give many
years of efficient service.
Should repairs still be necessary, please contact your KERN dealer or our Technical
Department.

4 Assembly
The first step is to position the microscope stand on a firm, level surface. The term
stand covers the stand base (standing surface) as well as the metal pillar which is
connected to it.
The holder is already on pillar of the stand, but you must always check whether it is
fixed securely and that it is in the correct position (preferably centrally and facing to
the front).
Please see section 5.5 for more details on adjusting the stand.
The next step is to place the microscope head on the holder, by passing the
objective through the holder ring until the rest of the head is above the ring.
You must use the small silver adjusting screw on the front of the holder ring to fix the
head in place.
The alignment of the microscope head is left to the user to do and can be adjusted to
suit the individual application situations.
To make it easier to operate the focus wheels or lighting control for example, we
recommend that you position the head with the tube connectors centrally to the front.
Ideally, the holder and head are then parallel on the central axis of the stand base
(see figure on page 10).
Then you can remove the protective caps from the tube connectors so that you can
then fit the eyepieces. When doing this, please be particularly careful that you do
not touch the optical lenses with your fingers and that no dust enters the
apertures.
You should also never fit two eyepieces with different magnifications.
With regard to the use of a device with lighting (OSF 523, OSF 525, OSF 527) you
must make sure that the frosted glass stand inlay is fitted in the centre of the
stand base, so that the transmitted light can be used correctly.
Also, when using reflected light please make sure, that the connection cable
between the holder and upper side of the pillar is plugged in.
Additional optional attachments:
The eye cups supplied with the microscopes can be fitted to the eyepieces.
(see section 5.6).
