

In the case of extremely high temperatures leave the area immediately
should vision become obscured.



If working in areas subject to risk of explosion spray the mask with an
antistatic spray which is compatible with the eyes and skin and which will
not damage rubber and plastics.

After use, remove the filter (or breathing tube) before cleaning and disinfecting.

6 CLEANING AND DISINFECTING

Disassemble the face mask only if it is particularly dirty or if it is difficult to clean
by washing only.
Clean the face mask with warm water and neutral detergent. Do not use organic
solvents for cleaning the visor and the rubber parts. Disinfect the face mask after
every cleaning cycle by soaking it in a disinfectant bath. Use only disinfectants
that will not damage the rubber and plastic components of the mask. Rinse
thoroughly under running water and allow to air dry away from direct sun light
and at temperatures lower than 50°C.

7 CONSERVATION STORAGE AND TRANSPORT
7.1 Conservation

After the cleaning and disinfecting operations put the face mask into its original
packaging away from intense light, temperature extremes, humidity or altering
radiation. Avoid stacking or placing objects on top which could deform or
damage the face mask’s profile.

7.2 Storage

New, unused face masks are to be kept in their original packaging away from
excessive humidity and possibly at ambient temperature.

7.3 Transport

Keep masks in their original packaging during transport

8. MAINTENANCE, PERIODIC CHECKS, REPAIRS
8.1 Disassembly

-Unhook straps from visor frame and remove harness.
-Remove screw from bottom of visor frame and take visor out of the face blank.
-Slip the inner half mask out of the speech diaphragm and the exhalation valve
seat and remove.
-Unscrew  the  speech  diaphragm  from  the  inside  turning  it  in  an  anticlockwise
direction and remove the internal guard taking care not to mislay the sealing O-
rings.
-Unscrew  the  exhalation  valve  assembly  from  the  inside  turning  60°
anticlockwise.
-Remove the equipment connector taking care not to misplace the O-rings.
-Clean the various components, inspect visually paying particular attention to the
rubber  gaskets  and  the  inhalation  and  exhalation  valves  and,  if  necessary,
replace damaged or worn parts.

8.2 Assembly

-Rub some silicone grease on gaskets and O-rings.
-Re-assemble the face mask following the steps at point 8.1. backwards taking
care not to damage the inhalation and exhalation valves during assembly.
-Tighten speech diaphragm and exhalation valve assembly.

Make sure all the components have been assembled correctly

8.3 Periodic checks and maintenance

The efficiency of the full face mask depends on the maintenance carried out and
the periodic replacement of some of its parts as detailed in the table below:

No special tools are required for the replacement of the above listed parts.
Valves are identified by the following colours:
  - Inner mask inhalation valve: RED
  - Mask inhalation valve: YELLOW
  - Mask exhalation valve: BLACK

The year of production of the exhalation valves is indicated in Annex "A" to the
last page of this manual.

Operation and seal fit testing require special testing equipment which can be
supplied by KASCO on request.
