Maintenance And Cleaning - Kemper autodark 660i Mode D'emploi

For your protection and maximum efficiency, please read this information
carefully before use.
► BEFORE WELDING
• E nsure that the helmet is correctly assembled and that it completely blocks any
accidental light. In the front, light may enter the helmet only through the viewing area
of the autodarkening welding filter.
• Adjust the headgear to ensure maximum comfort and to provide the largest field of vision.
• S elect a suitable welding filter for the shield. Dimensions of the filter: 110x90mm.
• Check the prescribed shade level for your welding application and adjust your
autodarkening filter accordingly (see the table with recommended shade levels).
► PRECAUTIONS
• Never place the helmet or the autodarkening welding filter on hot surface.
• Scratched or damaged protection screens should be regularly replaced by original
KEMPER ones. Before using the new protection screen, make sure to remove any
additional protection foil from both sides.
• Use only KEMPER autodark
• Do not expose the autodarkening welding filter to liquids and protect it from dirt.
• Use only original KEMPER spare parts. In case of doubt, please contact your KEMPER
authorized dealer.
• Failure to follow these instructions will invalidate the warranty. KEMPER does not accept
responsibility for any problems which may arise from applications other than welding,
or if the instructions for use are not strictly followed. The KEMPER autodark
helmet is manufactured to protect the welder's face against spatters and hazardous
ultraviolet and infrared rays emitted during the welding process. It is not intended to be
used as a protection against impact, flying particles, molten metals, corrosive liquids
or hazardous gases.
• Materials which may come into contact with the wearer's skin could cause allergic
reactions to susceptible individuals.
• Welding helmet worn over standard ophthalmic spectacles may transmit impact, thus
create a hazard to the wearer.
• If the helmet and the protection screen both do not carry the B marking, then only the
S marking is valid.
• A distance of at least 50cm, and never less than 25cm, between the welding arc and
the welder eyes is recommended for all welding applications.
► STORAGE
When not in use the filter should be stored in a dry place within the temperature range
of -20°C to +65°C. Prolonged exposure to temperatures above 45°C may decrease the
battery lifetime of the autodarkening welding filter. It is recommended to keep the solar
cells of the autodarkening welding filter in the dark or not exposed to light during storage
in order to maintain power down mode. This can be achieved by simply placing the filter
face down on the storage shelf.

► MAINTENANCE AND CLEANING

It is always necessary to keep the solar cells and the light sensors of the autodarkening
welding filter free of dust and spatters: cleaning can be done with a soft tissue or a cloth
soaked in mild detergent (or alcohol). Never use aggressive solvents such as acetone.
KEMPER filters should always be protected from both sides by protection screens
(polycarbonate or CR39), which should also be only cleaned with a soft tissue or cloth. If
protection screens are in any way damaged, they must be immediately replaced.
