Safety regulations
Repairs and servicing
• Only Leica-trained service technicians, or technical
specialists assigned by the person in charge
of the instrument, are permitted to carry out repairs.
• Only original Leica spare parts may be used.
• Disconnect the power cable before opening the
transformer, otherwise there is a risk of injury through
electric shock.
Precautions by the manufacturer
• The motor-focus system is electromagnetically
compatible in accordance with the directive 89/336/EEC
and can be operated at the same time as other
electrical appliances.
• Low-voltage protection prevents electric shock if the
circuit inside the motor housing is touched.
• Stops on the column, and end-switches on the motor
housing, limit the upward and downward movement of the
motor-focus system. The end-switches prevent it from
attempting to travel further when it encounters the stops.
Warning: Danger of crushing and other injuries
When focusing, keep your fingers away from:
• the space between the motor housing and the lower stop
• the space between the objective and the object, the
surface of the stand, the stage insert and the stage.
Precautions by the manufacturer: The lower stop must be
adjusted individually in accordance with the characteristics
of the object (see below).
Safety note
Always set the lower stop correctly in relation to the object
(see page 9). If it is set too low:
• the user’s hands might get crushed between the objective
and the object
• the object might get flattened or otherwise damaged
• the objective might get damaged.
Power cable
• Inspect the power cable regularly for damage. If it is
defective, replace it immediately, because it can cause
the instrument and ancillary equipment to become
electrically live, endangering personnel. Do not pull at
the power cable.
• Position the power cable carefully and make sure that
no-one can become entangled in it or fall over it.
Cleaning
• Disconnect the power cable before you attempt to clean the
motor-focus system.
• Respect the warning signs relating to the handling of liquids.
• Read and follow the notes about cleaning which are given in
the user manual for the instrument.
Liquids
Be careful when handling liquids. If spilt on electrical
appliances, they can:
• cause the instruments and accessories to become
electrically live, endangering personnel
• cause damage to the equipment.
Legal requirements
Adhere to general and local regulations relating to accident
prevention and environmental protection.
Conformity with European Community directive
The motor-focus system and its accessories are constructed in
accordance with the latest technologies and are provided with
a statement of conformity with EC requirements.
