3 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.
3.1 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 disinfection.
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.
3.2 Storage
After cleaning, store the equipment in a dry and clean place at room temperature. Avoid
exposing it to direct sunlight.
Lower the visor. Fig. 5.
