4. Maintenance and storage
•
Store protected from direct sunlight, at -10...+50 °C and relative humidity (RH) under 75 %.
A properly stored, unused face shield stays in good condition for a long storage period.
•
Clean with a damp cloth or sponge, using lukewarm water and mild detergent (neutral, pH
6-8) (e.g. washing-up liquid) (be careful not to scratch the visor). Do not wash under running
water, keep water away from the air channel and hose.
•
Do not use solvents (e.g. acetone, turpentine), hot water or bleaching agents (perborate,
percarbonate). Never clean with compressed air or compressed water.
•
Check that the visor and the face seal are undamaged. Replace by rewinding the buckle and
the buckle pin.
•
Check that the breathing hose is undamaged and replace a broken one.
•
Check that the hood of an Automask Litehood is undamaged and replace when necessary.
•
Maintenance of the blower units is described in the respective Instructions for Use.
•
Only use original spare parts.
•
The Automask is coarse waste. A very contaminated face shield as well as used fi lters
are special refuse and shall be disposed of according to the fi ltered substances (gases or
particles.

*) Provided that the maximum permissible detrimental gas concentration for the gas fi lter is not exceeded.
For power-assisted fi ltering devices with gas fi lter, concentration must not exceed 0.05 vol.% in gas fi lter
class 1 and 0.1 vol.% in gas fi lter class 2 and 0.5 vol.% in gas fi lter class 3.
**) If national guidelines exist: in all cases the lowest value applies.

Remarks, limitations
"Open" facepieces, such as helmets or hoods,
do not provide suffi cient protection in case of
breakdown or inferior output of the blower.
Therefore, devices of class TH1 must never be
used against carcinogenic, very poisonous or
radioactive gases and vapours.
For devices with combined fi lter apply the
relevant limitations of gas and particle fi lters.
