DONNING AND ADJUSTING THE RESPIRATOR
W
WARNING
Do not remove this respirator while in the contaminated area. Always don and remove the respirator in a
clean environment.
Failure to do so may expose the wearer to respiratory hazards and could result in
sickness and/or death.
Always wear ANSI Z87.1 compliant safety spectacles in addition to any welding headgear. Failure to do so
may result in permanent eye injury and vision loss. In Canada, users should follow CSA Z94.3 and/or the
eyewear requirements of the authority having jurisdiction in their region.
3M does not recommend use of the 3M
™
Speedglas
™
Welding Helmets 9100 Air and 9100 FX-Air with facial
hair that interferes with the faceseal. Users should be clean-shaven where the respirator’s faceseal comes
into contact with the user’s face.
Failure to do so may reduce the effectiveness of the respirator and may
result in sickness or death.
• Verify that the respirator is connected to the proper air source and that air is fl owing before donning the
respirator.
• For airline, verify line pressure is in required range of air control device per the recommended pressure
schedule and airline hose length.
• Put the respirator on your head so that the faceshield is directly in front of your face.
Pull the headgear fi rmly onto your head. If the headgear does not fi t your head snugly follow the instructions
directly below.
The following adjustments should be made to help ensure that the 3M
™ Speedglas ™ Welding Helmets 9100 Air
and 9100 FX-Air (Steps 1-6) are adjusted and fi tted prior to use.
1. Place the 3M
™ Speedglas ™ Welding Helmet 9100 FX-Air on the head and tighten the ratchet on the back of
the headgear (Fig.1) until a comfortable, but secure fi t is achieved. If a comfortable fi t cannot be achieved
using the ratchet alone, use the coarse adjustment of the front headband where the L, M, S adjustment are as
shown in the bottom of Fig. 1. L refers to a larger head circumference, M is for medium head circumference
and S is for smaller head circumference. Adjust the coarse adjustment based on the head circumference,
and then replace the helmet on the head and tighten the ratchet to achieve a comfortable but secure fi t. For
additional adjustment, the ratchet may also be turned 180 degrees to achieve a slightly different fi t based on
position as show in Fig. 2.
2. The 2 top crown straps should be adjusted to assure that the weight of the helmet is distributed and carried
evenly on the top of the head. With the helmet on, and the ratchet tightened, check to make sure that both
crown straps are adjusted so that there is no excess space or gaps between the top of the head, and the
crown straps. At times the back crown strap may be too large, and cause a gap, but this is not an appropriate
manner of wearing the helmet. If there is a gap, adjust the crown straps by sliding and tightening as shown
in Fig. 1. If there is no gap, but the helmet feels as though it is too high on the head, loosen the crown straps
until a comfortable height is achieved.
