tube (i.e. end with the blue pinch clip) onto the air inlet of the headgear (Fig. 1a). The breathing tube
should make an audible click when attached. Verify breathing tube is secured to the headgear by
pulling on the connection. If it is not securely connected, detach and reconnect.

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: 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: with the headgear upside down, moving up the "ladder" will raise the position of the
headband. Moving down the "ladder" will lower it.
iii. 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.
