4. Maintenance
The person who is responsible for cleaning and maintenance
of the equipment must have suitable training and be well
acquainted with work of this type.
4.1 Cleaning
Sundström cleaning tissues SR 5226 are recommended for
daily care.
If the equipment is more heavily fouled, the sweatband can
be washed with a mild soap solution.
If necessary, spray the face shield with 70 % ethanol or
isopropanol solution for desinfection.
Wipe the plastic protective lens carefully, since they are
sensitive to scratching.
Automatic welding filters are very sensitive to moisture.
Use only a dry polishing cloth.
NOTE! Never use solvents for cleaning.
4.2 Storage
After cleaning, store the equipment in a dry and clean place
at room temperature. Avoid exposing it to direct sunlight.
4.3 Maintenance schedule
