Donning & Fitting
W WARNING
Failure to follow these instructions may reduce respirator performance, overexpose you to
contaminants, and may result in sickness or death:
a. Users must be clean-shaven where the respirator's face seal comes into contact with their face (M-100,
M-200 and M-300 Series).
b. Always properly assemble and wear both the inner and outer shroud (M-400 Series).
c. Ensure visor frame firmly latches in the closed position. Replace worn or damaged parts if required (M-
400 Series).
d. The M-Series Headgear is one component of an approved respiratory protection system. Always read
and follow all User Instructions supplied with your M-Series Headgear, 3M™ PAPR Blower Unit or
Supplied Air Device in order to ensure correct system operation.
e. Do not use with parts or accessories other than those manufactured by 3M as described in these User
Instructions or on the NIOSH approval label for this respirator.
The following instructions cover donning and fitting your 3M™ Headgear. Follow the User Instructions for
your 3M™ PAPR or Supplied Air Unit to properly assemble, don, and fit your specific air source. Complete
all necessary performance checks as described in those User Instructions and verify that the airflow is
adequate before donning your headgear and entering a contaminated environment.
NOTE: You may want to have a colleague help check for proper donning.
1. Connect an approved breathing tube to the headgear. See Connection and Disconnecting Breathing
Tubes section for additional information.
2. With the visor (lens) in the up position, place the headgear on your head.
3. Turn the ratchet knob at the back of the suspension clockwise until the suspension feels snug but
comfortable. Turn counterclockwise to loosen, if needed. The suspension fits head sizes from
51-64 cm (US hat sizes 6 3/8 to 8). An optional size reducing ratchet comfort pad (M-956) is available
to provide additional comfort. This comfort pad also can be used to improve fit and stability for
smaller head sizes. See Replacement Parts and Accessories section of these User Instructions for
additional information.
4. If the height on your head or the balance of the headgear is not comfortable, remove the headgear,
turn upside down, and adjust the suspension.
a. The suspension headband can be adjusted at four locations. There are two adjustment locations in the rear
of the headgear and two in the front. To change the position of the headband, pull the height adjustment
slot off the peg and re-position to another slot on the "ladder" (Fig. 2). Each location can be adjusted
independently for a custom fit.
i. M-100 and M-200: with the headgear upside down, moving up the "ladder" will lower the position of
the headband. Moving down the "ladder" will raise it.
ii. M-300 and M-400: with the headgear upside down, moving up the "ladder" will raise the position of the
headband. Moving down the "ladder" will lower it.

b. M-100 and M-200 Series Headgear Only: The fabric straps of the M-150 Head Suspension can be adjusted
by sliding the blue strap lock located on the center strap (Fig. 3). Sliding the buckle towards the rear of
the headgear tightens the straps and will raise the height of the headgear on the head. Sliding the buckle
towards the front of the headgear loosens the straps and will lower the height of the headgear on the head.
5. Lower the visor into the down position.
a. M-100, M-200 and M-300: Pull down on the loop located on the faceseal. Ensure the visor is fully down
and covering your face. The headgear should sit level on your head with the faceseal gently hugging your
face. If using the M-985 Earmuff Assembly or M-976 Head, Neck, and Shoulder Cover, ensure it does not
interfere with the faceseal. The elasticized edge of the faceseal should come into contact with the skin
under the chin and around the jaw.
b. M-400: Ensure visor is firmly closed (completely latched) in the down position. You should hear an audible
"click" when it is fully closed. Tighten the adjustable cord on the inner shroud until there is less than a two
finger gap between your skin and the inner shroud. Leave the outer shroud draped over your shoulders.
6. If needed, adjust the airflow inside the headgear for wearing comfort. To adjust, raise the visor into
the up (open) position. Locate the blue air deflector in the front of the headgear and rotate. Fig. 4
shows where the air deflector is located. There are two positions. Adjust fully open for more airflow
across the face or partially closed to re-direct a portion of the air towards the visor. After adjusting the
air deflector, lower the visor back into the down position.
NOTE: Do not adjust the air deflector while in a contaminated area.
