Maintenance
The 6500 half mask must be inspected before each use to ensure
it is in proper operating condition. Any damaged or defective
part must be replaced before use. The following procedure is
suggested.
1. Check the face mask for cracks, tears and dirt. Examine the
inhalation valves for signs of distortion, cracking or tearing.
2. Check that the head straps are intact and have good
elasticity.
3. Examine all plastic parts and gaskets for signs of cracking or
fatigue and replace if necessary.
4. Remove the exhalation valve cover and exhalation valve and
examine for signs of dirt, distortion, cracking, or tearing.
Replace the parts where necessary. Secure the valve cover
prior to use
Use Limitation
1. These respirators do not supply oxygen. Do not use in
oxygen deficient areas.*
2. Do not use for respiratory protection against atmospheric
contaminants which have poor warning properties, are
unknown or immediately dangerous to life and health, or
against chemicals, which generate high heats of reaction
with chemical filters.
3. Do not modify or alter this device.
4. The assembled respirator may not provide a satisfactory face
seal with certain physical characteristics (such as beards or
large side burns) resulting in leakage between the respirator
and the face. The user assumes all risks of bodily injury,
which may possibly result.
5. Do not use with unknown concentrations of contaminants.
6. Do not use for escape purposes.
7. Leave the work area immediately and check the integrity of
the respirator and replace respirator and / or filters if:
- Damage has occurred or is apparent.
- Breathing becomes dicult or increased breathing
resistance occurs.
- Dizziness or other distress occurs.
- You taste or smell the contaminant or an irritation occurs.
8. Store this device in a sealed container away from
contaminated areas when not in use.
5. Use strictly in accordance with respirator and filter user
