Leica DM 750 Manual 8

Instructions on use

Intended use

The Leica DM 750 microscope is an optical

instrument which uses magniﬁcation and illu-

mination to improve the visibility of objects. It

is used for observing and documenting.

The Leica DM 750 microscope may be used only

in closed rooms and must be placed on a solid

ﬂoor.

The Leica DM 750 microscope can be used in

clean rooms without any problems.

• Position the Leica DM 750 microscope

so that it can be disconnected from

the power supply at any time. The power cord

must remain accessible at all times, because the

power supply is foreseen as mains disconnect-

ing device.

Place of use

Only use the instruments in closed, dust free

rooms and between +10 °C and +40°C. Protect

the devices from oil, chemicals and extreme

humidity. If using the devices outdoors, protect

them from dust and moisture. Never use electri-

cal devices outdoors. Install electrical devices at

least 10 cm from the wall and away from ﬂam-

mable substances.

Avoid large temperature ﬂuctuations, direct

sunlight and vibrations. These conditions

can distort measurements and micrographic

images.

In warm and warm-damp climatic zones,

the individual components require

special care in order to prevent the build-up of

fungus.

Non-intended use

• Using the instrument in any way

contrary to the speciﬁcations in the user

manual can lead to bodily harm and damage to

objects. Doing so can impair the functions of

the protective measures provided.

Never install any other plug (NEMA

5-15P) or unscrew any mechanical

components unless expressly instructed to do

so in the instructions.

The devices and accessories described in

this operating manual have been tested

for safety and potential hazards.

Leica DM 750 Manual 9

Instructions on use (continued)

• The responsible Leica aﬃliate must be

consulted whenever the instrument is

altered, modiﬁed or used in conjunction with

non-Leica components that are outside of the

scope of this manual.

• Unauthorized alterations to the device

or noncompliant use shall void all rights

to any warranty claims.

Transport

If at all possible, use the original packaging for

shipping or transporting individual modules.

In order to prevent damage from vibrations,

disassemble all moving parts that (according to

the user manual) can be assembled and disas-

sembled by the customer and pack them sepa-

rately.

Disposal

Disposal must comply with locally applicable

laws and regulations.

Integration in third-party products

When installing Leica products into third-party

products, the manufacturer of the complete

system or its dealer is responsible for follow-

ing all applicable safety instructions, laws and

guidelines.

Leica DM 750 Manual 10

Health risks and dangers of use

Health risks

Workplaces with microscopes facilitate

and improve the viewing task, but they

also impose high demands on the eyes and

holding muscles of the user. Depending on the

duration of uninterrupted work, asthenopia

and musculoskeletal problems may occur. For

this reason, appropriate measures for reduction

of the workload must be taken:

Optimum workplace layoutϘ

Frequent changes of activityϘ

Thorough training of the personnel, givingϘ

consideration to ergonomic and organiza-

tional aspects

The ergonomic design and construction of the

Leica microscopy series are intended to reduce

the exertion of the user to a minimum.

Danger of infection

• Direct contact with eyepieces is a poten-

tial transmission method for bacterial

and viral infections of the eye.

The risk can be kept to a minimum by

using personal eyepieces for each indi-

vidual or detachable eyecups.

Dangers during use

The Leica DM 750 microscope may only beϘ

connected to a grounded socket.

The Leica DM 750 microscope may not beϘ

operated unless it is in proper functioning

condition.
