Important Notes

Leica A60 S User Manual Safety Instructions 6
Intended use
The Leica A60 S stereomicroscope is an opti-
cal instrument for improving the visibility of
objects through magnification and illumina-
tion.
The stereomicroscope may be used only in
closed rooms and must be placed on a solid
substrate.
Always position the stereomicroscope
so that you can disconnect the illu-
mination from the power supply at any time.
The power cable must remain accessible at all
times, because the power cable is intended as a
power disconnect device.
Place of use
Use the stereomicroscope in closed, dust-free
rooms at +10°C to +40 °C. Protect it from oil,
chemicals and extreme humidity. Install elec-
trical devices at least 10 cm from the wall and
away from flammable substances.
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 stereomicroscope in any way
other than that described in the user
manual may result in personal injury or damage
to property. 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 instruments and accessories
described in this user manual have been
tested for safety and potential hazards.
Instructions on Use

Leica A60 S User Manual Safety Instructions 7
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 instru-
ment 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, the
customer should disassemble all moving parts
according to the user manual and pack them
separately.
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.
Instructions on Use (Continued)

Leica A60 S User Manual Safety Instructions 8
Health risks
Workplaces with stereomicroscopes
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 at such a
workplace, impaired vision and problems with
the musculoskeletal system may occur. For this
reason, appropriate measures for reduction of
the workload must be taken:
OOptimum workplace layout
OFrequent changes of activity
OThorough training of the personnel, giving
consideration to ergonomic and organiza-
tional aspects
The ergonomic optical design and construction
of the Leica stereomicroscopes are intended to
reduce the exertion of the user to a minimum.
Danger of infection
Direct contact with eyepieces is a
potential 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
OThe stereomicroscope must be connected
to a grounded outlet.
OThe stereomicroscope may be used when it
is in proper working condition only.
Health Risks and Dangers of Use

Leica A60 S User Manual Safety Instructions 9
Information for the person responsible for

thorized persons, is improperly maintained
(as long as maintenance was not carried
out by us), or is handled improperly, Leica
will not accept any liability.
OThe electric installation in the building
must conform to the national standard, e.g.
current-operated ground leakage protec-
tion (fault-current protection) is suggested.

Instructions for safe assembly
Due to the heavy weight of the base-
plate, improper use can cause injuries
or damage to the surrounding area. Therefore,
always request assistance for assembly.
Installing the column
1. Push the tapping screw through the base-
plate from below.
2. Fit the serrated lock washer onto the screw.
3. Screw the column in place using the Allen
key provided.

Mounting the horizontal arm
1. Push the cross-member with the horizon-
tal arm over the column so that the cross-
member lies securely on the safety ring. You
can now rotate the horizontal arm in any
direction desired.
Safety Ring and Horizontal Arm
Installing the safety ring
The safety ring is the most important
safety element of the entire configura-
tion. It protects the horizontal arm against fall-
ing down accidentally.
1. Slide the safety ring over the column and
tighten the clamping screw.
Fastening the horizontal arm
For safety reasons, you should fasten
the horizontal arm in place when you
leave your workstation.
1. Rotate the horizontal arm into a secure
position.
2. Carefully tighten the clamping screw on
the cross-member.
