Failure to follow all instructions on the use of this product and/or failure to wear the respirator system
during all times of exposure may adversely affect the wearer's health, may lead to severe illness or
permanent disability and may render any warranty null and void.

SYSTEM DESCRIPTION
The 700 Series headtops combine head, eye and respiratory protection (also welding for HT-748 and HT-749) and
are designed to be used with an approved air filter unit (AFU) or regulator (see Reference leaflet) to form a
respiratory protection device.
The air will be fed via a breathing tube from a belt mounted AFU or regulator to the back of the headtop. The air
flows over the top of the wearer's head and down in front of the face. The visor and combined head and face seal
prevent the ingress of contaminated air.

Do not use oxygen or oxygen enriched air.
Do not use in flammable or explosive atmospheres (Call 3M OH&ES Technical Affairs at your local 3M office).
If using in Supplied Air mode ensure that:
• The source of the air supply is known;
• The purity of the air supply is known;
• The air supply is of a breathable quality, to EN12021 (UK customers use BS4275).
Only suitable for use by clean-shaven personnel, facial hair under the seal reduces protection.

High winds above 2m/s, or very high work rates (where the pressure within the headtop can become negative) can
reduce protection. Adjust equipment as appropriate or consider an alternative form of respiratory protective device.
Materials which may come into contact with the wearers skin are not known to cause allergic reactions to the
