USE OF THE DRINKING SYSTEM
The drinking system can only be used with a bottle equipped with a special valve or with CamelBak
hydration systems. Connect the suction valve to the bottle or a CamelBak hydration system after
removing its cover. Turn the bottle upside down and turn the drinking system valve 90° on the
facepiece and start to drink. Drinking system capacity is approximately 200 ml per minute. When
finished drinking, turn the drinking system valve back. Disconnect the bottle, cover the suction valve
and fix it on the facepiece.

MAINTENANCE
Dry the inside of the mask with a clean cloth after every use. The mask must be dry before being
stored in the carrying bag. Allow the mask to air dry without exposure to direct sunlight or radiant
heat. If the mask was previously worn by another user, disinfection with a 2% chloramine solution is
recommended. Allow it to air dry before further use.
After extended use, wash the mask with water and soap, bicarbonate or a detergent solution. Rinse
with clean water and allow it to air dry.
All maintenance and cleaning must be performed without a filter attached. Do not use any organic
solvents (petrol, toluene, etc.) on the mask. Check all valve chamber parts and clean as needed
after use in a dusty environment. Removable parts can be exchanged according to the following
instructions.
EXHALATION VALVE REPLACEMENT
1. Turn the exhalation chamber cover 90° and remove it.
2. Pull out the exhalation valve to remove it.
3. Clean the valve and exhalation chamber with lukewarm water and allow to air dry. Take special
care to clean the valve and valve contact line.
4. Insert the spindle of the cleaned or new valve into the exhalation chamber aperture and gently
press it into the correct position.
5. Replace the exhalation chamber cover.
6. Perform a mask tightness test.

CM-7M PROTECTIVE MASK
!
!
DIRECTIONS FOR USE
!
!
The CM-7M protective mask, when combined with a suitable filter or breathing apparatus provides
effective protection for the eyes, face and lungs from the effects of toxic substances, radioactive
materials and biological warfare agents, including gases, vapors and aerosols. Functional reliability
is guaranteed within a temperature range of -30ºC to +70ºC. The protective mask can be used with
a filter if the ambient atmosphere contains at least 17% oxygen, otherwise a breathing apparatus
must be used. The protective mask cannot be used in oxygen atmosphere or in environments with
enriched oxygen.
Components of the protective mask
:
1 – rubber face cover
2 – two visors
3 – strapping system
4 – speaker body + insert
5 – exhalation chamber
6 – two inhalation chambers
7 – fluid intake system
8 – plastic bottle with special stopper
!
STORAGE
CM-7M masks must be stored in a cool, dark and dust-free place at 15–77°F without sudden
temperature fluctuations. The storage room should be ventilated regularly and relative humidity kept
below 80%. Do not expose stored masks to radiant heat or sunshine. Fuels, solvents, lubricants and
other inflammable substances, including chemicals, must not be stored with masks. Moreover, do not
store with any electrical machines or appliances that produce sparks or discharges during operation
(ozone creation). Avoid deformation of the rubber facepiece and internal mask during storage. Wax
blooms that may naturally occur on the surface of the face part and the interior of the mask are
normal. The wax protects the mask from the effects of ozone.
