2. Lift the Y-branches of the BT-60 Series tube along with the Fullface 

Mask over your head so the Y-branches of the breathing tube are resting 

on your shoulders and the faceseal of the Fullface Mask is in front of 

you.

3. Hold the front of the Fullface Mask with one hand and the straps away 

from the Fullface Mask with the other hand, creating an opening for the 

head.

4. Pull the Fullface Mask assembly down over the head with the 

headstraps at the back of the head.

5. Place the nose in the nose cup and chin in the chin cup area then 

press the Fullface Mask firmly and evenly against the face (Fig.12).

6. Tighten the bottom straps one at a time. Be careful to tighten both 

sides equally (Fig. 13).

7. Tighten the remaining straps one at a time. Be careful to tighten both 

sides equally (Fig. 14).

Note: You may find it easier to lift the breathing tube over the head so it 

rests at the front of the body, which allows the bottom straps to be 

tightened more easily (Fig. 15 ). After tightening the straps, lift the 

breathing tube over the head so it rests at your back (Fig. 16).

FIT CHECK

Positive Pressure User Seal Check

1. Place the palm of your hand over the exhalation valve and exhale 

gently. If Fullface/Half Mask bulges slightly and no air leaks are detected 

between your face and the Fullface/Half Mask, a proper fit has been 

obtained (See Fig. 17a, 17b or 17c depending on Fullface/Half Mask).

2. If faceseal air leakage is detected, reposition the Fullface/Half Mask 

on your face and/or readjust tension of the straps to eliminate the 

leakage. Repeat step 1.

Negative Pressure User Seal Check

1. Completely plug the Powered Air Turbo end of the breathing tube with 

the palm of your hand (Fig. 18).

2. Inhale gently and hold your breath for 5 to 10 seconds. If the 

Fullface/Half Mask collapses slightly, a proper fit has been obtained.

3. If air leakage is detected, reposition the Fullface/Half Mask on your 

face and/or readjust the tension of the straps to eliminate the leakage. 

Repeat steps 1-2.

 If you CANNOT achieve a proper fit DO NOT enter the hazardous 

area.

Users should be fit tested in accordance with national requirements.

For information regarding fit testing procedures, please contact 3M.

Connecting and donning Powered Air Turbo

1. Insert the bottom end of the breathing tube into the outlet of the 

Powered Air Turbo and turn the end of the breathing tube to ensure it is 

fitted firmly.

2. Switch on the Powered Air Turbo by pressing the on button for 1 

second. See TR-602E/TR-802E Powered Air Turbo User Instructions for 

information to ensure the Powered Air Turbo is operating correctly. Note: 

The BT-60 Series Breathing tube must be connected to the 

TR-602E/TR-802E Powered Air Turbo prior to powering on the Powered 

Air Turbo in order to activate tight-fitting mode. If the Powered Air Turbo 

is powered on prior to connecting the BT-60 Series Breathing Tube the 

Powered Air Turbo will operate in loose-fitting mode. To activate 

tight-fitting mode the Powered Air Turbo must be turned off and restarted 

with the BT-60 Series breathing tube installed Tight-fitting mode is 

indicated on the Powered Air Turbo when the Facepiece icon is lit (see 

Fig 2). Once the Powered Air Turbo is running in tight-fitting mode it will 

remain in tight-fitting mode, even if the breathing tube is removed, as 

long as the Powered Air Turbo is not powered down. In tight-fitting mode, 

the Powered Air Turbo operates at lower preset speeds designed to be 

more comfortable for the Fullface/Half Mask wearer.

3. Adjust and buckle the waist belt with the Powered Air Turbo fitted 

comfortably around your waist and ensure the breathing tube is not 

twisted.

IN USE

Use in the power off state is not normal. However, reduced protection is
