Find the approved pressure range for the length of hose you are using from the label on the air control

device or from the appropriate air control device User Instructions.

Read the pressure gauge located where you are attaching the compressed air hose to the source of

breathing air to verify that the pressure is within the approved range. Adjust the pressure, as needed,

within that range. Connect the supplied air hose to the breathing air source. Air should begin ﬂowing.

Place your hand inside the headgear, in the area above the faceshield. You should feel the air entering

the headgear.

Check to be sure that the breathing tube is securely clamped over the helmet air inlet and connected to

the air control device securely, according to the User Instructions for the air control device you are using.

Put the respirator on your head so that the faceshield is directly in front of your face.

Pull the suspension ﬁrmly onto your head. Turn your head from side to side, then nod your head up

and down. If the suspension does not ﬁt your head snugly or if the height on your head or the balance

of the headgear is not comfortable, remove the headgear and adjust the suspension according to the

“Assembly” section of these User Instructions.

Secure the chin strap if necessary for greater stability.

WARNING

If this respirator fails any of the requirements of the user inspection and performance check, do

not use the respirator until all necessary repairs have been made and the respirator passes the

performance check. Failure to do so may adversely affect respirator performance and result in

sickness or death.

WARNING

Your employer must provide compressed breathing air that meets at least the requirements of the

speciﬁcation for Grade D breathing air as described in the Compressed Gas Association Commodity

Speciﬁcation G-7.1-1997 in the United States. In Canada, refer to CSA standard Z180.1, table for

the quality of compressed breathing air. Failure to do so may result in sickness or death.

You must comply with OSHA standard 29 CFR 1910.134, which states that, “Airline couplings

shall be incompatible with outlets for other gas systems to prevent inadvertent servicing of airline

respirators with nonrespirable gases or oxygen.” Failure to do so may result in sickness or death.

Don the Respirator

Do not remove the respirator while in a 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 or death.

1. Verify that the respirator is connected to the proper air source and that air is ﬂowing before donning

the respirator.

2. Verify that the air pressure at the point where the air supply hose is attached to the air source is in

the required range of the air control device.

3. Put the respirator on your head so that the faceshield is directly in front of your face.

4. Pull the suspension ﬁrmly onto your head. If the suspension does not ﬁt your head snugly or if the

height on your head or the balance of the headgear is not comfortable, remove the headgear and

adjust the suspension according to the, “Assembly” section of these User Instructions.

5. Pull the chin strap under your chin. If the chin strap does not ﬁt snugly, remove the headgear and

adjust the strap according to the “Assembly” section of these User Instructions.

6. With the helmet on your head, pull the inner shroud down around the shoulders or tuck it inside

your shirt. Tucking the inner shroud inside your shirt may allow air to ﬂow over your upper body for

greater comfort.

7. Pull the outer shroud down in the front and back. To keep the outer shroud in the proper position,

pull the elastic straps on the front panel of the outer shroud around the side of your body and fasten

the metal clips to the D-rings on the back panel of the outer shroud.

Check to be sure that the compressed air hose is not kinked or twisted. It should be protected from

sharp objects and heavy equipment that could roll over the hose.
