Full face mask M98 ENGLISH

013010 M98
013011 M98 Small
013030 M98 textile
013031 M98 Small textile

The mask M98 has been designed to conform with EN 136/12942 (Europe) and AS/NZS 1716:2003
(Australia/NZ). EC certified (013010 and 013011) by BGIA (Berufsgenossenschaftliches Institut für
Arbeitssicherheit), DE-53754 Sankt Augustin, Germany, ID: 0121. Licence 0858 by SAI Global,
Australia.

1. General

The mask M98 is designed to protect the respiratory system and face against hazardous gases and
particles.

Use as filter mask together with a Pro2000 filter (gas, particle or combined filters). The filters are

thread filters conforming to the European standard EN 148-1.
The filter is selected according to the type of hazard present.
The M98 Small is designed for persons with a small face.

2. Limitations of use

2.1 The filtering device must not be used if the environment and contamination is unknown. In

case of doubt, isolating respirators (air supply) which function independently of the atmosphere
must be used.

2.2 The filtering device must not be used in confined spaces (e.g. cisterns, tanks) because of the
risk of oxygen deficiency or presence of heavy oxygen-displacing gases (e.g. carbon dioxide).

2.3 The filtering device may be used only if the oxygen content of the air is 18–23 vol.%.

2.4 Gas filters do not protect against particles. Similarly, particle filters do not provide protection

against gases or vapours. In case of doubt, use combined filters.

2.5 Normal filtering devices do not protect against certain gases such as CO (carbon monoxide),
CO2 (carbon dioxide) and N2 (nitrogen).

2.6 Particle filters are only allowed for single use if they are applied against radioactive agents or
micro-organisms (virus, bacteria, fungi and spores).

2.7 It is likely that adequate protection cannot be guaranteed if the user’s beard, hair, spectacle
frames or clothing intrude into the faceseal. With the M98 one can use special spectacles (see
012790 spectacle frame).

2.8 When a breathing protector is used in explosive atmospheres, please follow the instructions
given for such areas.

2.9 Gas filters shall be replaced when the user begins to sense odour, taste or irritation. Filters
used against detrimental gases that do not display any significant indications, require special
regulations for the duration of use and correct usage.
Particle filters must be replaced at the latest when breathing resistance becomes too high.

2.10 The weight of filter used with a full face mask shall not exceed 500 g. The M98 is used with
one filter only (the other opening on the mask is blocked by the manufacturer).

4. Preparations for use, and Donning

Check before use

intactness of facepiece, rubber parts and visor
head harness condition and elasticity
that speech diaphragm is in place
that exhalation valve is in place and that its cover is properly fastened
that inh. and exh. valves function properly
that drinking device is properly fastened
that the filter is correct for the intended use. Filter type and class are evident from the marking.
that storage period of the filter has not been exceeded
filter condition and intactness. Shake the filter to ensure that there are no loose

components/contents The filter shall be replaced if it has been exposed to strong press or
impact. It may be damaged.

4.1 Fitting of the filter: Remove eventual safety plugs from the filter. Screw the filter tightly in the

connector of the mask (=inh. valve body).

4.2 When needed, connect the spectacles to the inner mask and adjust their position.

4.3 A sweat band is recommended to control excessive hair.

4.4 Loosen the head harness straps.

4.5 Locate the chin pocket of the mask properly on the chin and pull the head harness over the

head.

4.6 Check that the chin is in the chin pocket. Tighten the straps. Start with neck straps, pull backwards

(not outwards). Then adjust the temple straps and finally the upper strap. The cradle/net lies
centered on the back of the head.
Check that the faceseal touches the skin all around, especially under the chin pocket. Try moving
the mask sideways to verify that there is no slippage.

10

4.7 Check the tightness of the mask (two alternative methods):

1) Cover the exhalation opening of the mask with your hand. Exhale gently to create overpressure.

There must be no leakage between the face and the faceseal.

2) Cover the filter opening with your hand. Inhale to make the mask press onto your face.

If you fail to get a tight fit (=potential leakage), adjust the head harness and filter, or use another

size of the mask.

4.8 Using the drinking device

Use water or clear liquids (=avoid non-soluble particles).
Open the lids of the drink device and the bottle, insert the nozzle into the drinking device.
Take the mouth piece in the mouth and press it with the teeth to make water pass through.

o The bottle cap can also be connected to a standard PET bottle (thread Ø 28 mm).

5. Maintenance and storage

5.1 Test for function and leak-tightness

If components have been replaced (visor, valve discs or speech diaphragm), a test for function and
leak-tightness must be carried out with an appropriate test device (e.g. Pro-Tester, code 141080).
The test is also done in case of a mask stored unused for a longer period, and at least once a year.

Check also that the faceblank has maintained its shape, the head harness is reasonably elastic, the
visor and the faceseal are undamaged, and that the valve discs and the speech diaphragm’s O-ring
are good and well in position. Damage must be repaired.

5.2 Replacing the visor

The visor is available in polycarbonate or polycarbonate with a chemical-resistant and scratch-proof
coating. The material code is found at the left edge of the visor. Replace visor if damaged, dirty or
scratched.

Material code is shown by an arrow:
1 (not in use)
2 hard coated polycarbonate (HC)
3 (not in use)
F polycarbonate (PC)

Unscrew the screws (Torx 20), loosen the visor frames, and remove the visor (Fig. A)
Place a new visor in the faceblank (with the marking “UP” on the visor showing upwards). Align

the check marks of the visor and faceblank with each other (Fig. B).
Position the visor frames and tighten both screws (Fig. C).
Carry out the leak-tightness test (point 5.1).

5.3 Replacing the exhalation valve disc

Pull out the valve cover (Fig. D).
Separate the valve assembly from the valve cover and pinch on the edge of the disc (Fig. E).
Replace the disc. Press lightly on the tip of the disc to secure a good fit (Fig. F).

11

5.4 Replacing the inhalation valve discs

Remove the rubber valve seat (green) by pushing it with a finger from the inside of the mask

(Fig. G).
Replace the disc (pass the tail through the central hole to the inside of the mask) (Fig. H).
Put the valve seat back to the bottom of the valve body (Fig. J). Do not press too tight (the disc

comes immobilised) because the disc must be free to move.
The valve discs (green) of the inner mask are replaced similarly. Make sure that the rubber

edge of the inner mask comes in the valve seat groove.

5.5 Replacing the speech diaphragm

Remove the inner mask from around the speech diaphragm (Fig. K).
Press the clip to remove the speech diaphragm (Fig. L–M). To make assembly easier, moisten

the O-ring with water. Press the speech diaphragm into place.
Insert inner mask into place.

5.6 Replacing the harness buckle

Press the buckle downwards (Fig. N).
Hold the buckle and twist the rubber endpiece through the gap to the other end of the buckle

(Fig. O–P) (the buckle rotates 180 ).
Remove the buckle (Fig. Q).
Assemble in reverse order.

5.7 Replacing the inner mask
Remove first the inhalation valve seat (green) by pushing it with a finger from the inside of the

mask (Fig. G).
If equipped with drinking device: remove the mouth piece.
Gently pry open the hole on the fastening ring of the inner mask, using a screwdriver (via the

inh. valve body opening) until the fastening ring comes off (Fig. R).
Remove the inner mask (Fig. S).
When assembling, insert the notch of the fastening ring into the tip of the exh. valve (Fig. T) and

press the inner mask into place.

5.8 Cleaning
Mask

Remove the filter, valves/discs, drinking device, spectacle frame, speech diaphragm and inner

mask.
Clean the facepiece and components with a damp cloth or sponge, using lukewarm water and

mild detergent (neutral, pH 6-8) (e.g. washing-up liquid). A brush can be used for stubborn dirt

(be careful not to scratch the visor).
Do not use solvents (e.g. alcohol, acetone, turpentine), hot water or bleaching agents

(perborate, percarbonate).

Drinking device (Fig. U, V, X)

Remove the mouth piece and wash it separately.
Put water in a bottle. Connect the bottle to the drinking device. Squeeze the bottle and let water

pass through the drinking device.
Replace the mouth piece when the mask is given to another user.

5.9 Disinfection

After cleaning, disinfect the inside/faceseal with a disinfection solution (e.g. Scott Trigene), rinse and
allow to dry. Finally, reassemble the mask.

12

5.10 Storage
Storage protected from direct sunlight, at -10...+50 °C and relative humidity (RH) under 75 %

(sealed filters RH max. 95 %). A properly stored, unused mask stays in good condition for a

long storage period.
The components should not be more than 12 years old.
Before use, the mask must undergo a function test, see Table.
After use, an opened filter must be sealed tightly if it is to be reused, but it must be replaced

within 6 months at the latest.

5.11 Disposal
Masks (without filters) are coarse waste. A very contaminated mask and used filters are special

refuse and shall be disposed of according to the filtered substances (gases or particles).
