Facepiece to Breathing Tube Assembly
1. Align the two branches of the breathing tube over the two bayonet mounts on the facepiece. Ensure the one small slot on the breathing tube bayonet
aligns with the one small lug on the facepiece bayonet mount.
Note: The bayonet connectors of the BT-60 Series Breathing Tubes are identical, and can be used on either bayonet mount on the facepiece.
2. Twist each branch of the breathing tube clockwise a quarter turn until it meets the internal stop and is firmly seated on the bayonet. Do not forcibly
overturn, as the bayonet could be damaged (Fig. 5-6 for half-facepiece, Fig. 7-8 for full-facepiece).

SYSTEM DONNING AND USER SEAL CHECKS
Begin system donning with the breathing tube attached to the facepiece. Refer to "Facepiece to Breathing Tube Assembly" steps 1-2 for instructions.
Failure to follow these User Instructions may reduce respirator performance, overexpose you to contaminants, and may result in sickness or death.
• To help maintain a good seal between the face and the faceseal, the respirator faceseal must be clear of obstructions at all times. Do not use
with beards or facial hair that prevent direct contact between the face and the respirator faceseal. Do not use with corrective eyeglasses. If
corrective eyeglasses are required, a 3M™ Spectacle Kit must be used inside the respirator.
• Do not enter a contaminated area until the respirator system has been properly donned. Do not remove the respirator before leaving the
contaminated area.
Donning the Half Facepiece Respirator
1. Lift the Y-branches of the BT-60 Series Breathing Tube along with the facepiece over your head so the faceseal of the respirator is in front of you,
the Y-branches of the breathing tube are resting on your shoulders, and the trunk of the breathing tube is running down your back.
