SYSTEM DESCRIPTION

The 3M™ BT-Series Breathing Tube is designed to be used in 

conjunction with the 3M™ TR-602E Powered Air Turbo and an approved 

3M™ 6000 Series Fullface and 7500 Series Half Mask (see Reference 

Leaflets). These systems meet the requirements of AS/NZS 1716:2012 

(Respiratory protective devices - Powered filtering devices). The systems 

are intended to provide protection against a range of particulate/gas and 

vapour hazards or nuisance odours.

 WARNINGS AND LIMITATIONS

Use this respirator system strictly in accordance with all instructions:

• - contained in this booklet,

• - accompanying other components of the system. (e.g. 

TR-602E/TR-802E Powered Air Turbo Reference Leaflet, Filter User 

Instructions and Fullface or Half Mask User Instructions).

Refer to Technical Specification section for limitations relating to 

protection factors. Do not use in concentrations of contaminant requiring 

a greater protection factor stated in these user instructions.

Do not use for respiratory protection against unknown atmospheric 

contaminants or when concentrations of contaminants are unknown or 

immediately dangerous to life or health (IDLH).

Do not use in atmospheres containing less than 19.5% oxygen. (3M 

definition. Individual countries may apply their own limits on oxygen 

deficiency. Seek advice if in doubt).

Do not use these products in oxygen or oxygen-enriched atmospheres.

These products do not supply oxygen.

Only use with Powered Air Turbos, Fullface or Half Mask and 

Spares/Accessories listed in the reference leaflets and within the usage 

conditions given in the Technical Specification.

Only for use by trained competent personnel.

Leave the contaminated area immediately if:

a) Any part of the system becomes damaged.

b) Airflow into the facepiece decreases or stops

c) Low airflow or low battery alarms activate.

d) Breathing becomes difficult.

e) Dizziness or other distress occurs.

f) You smell or taste contaminants or irritation occurs.

Never modify or alter this product. Replace parts only with original 3M 

spare parts.

^

Do not use with beards or other facial hair that may inhibit 

contact between the face and the product thus preventing a good 

seal.

Only use with the spectacle kit available as an accessory with this 

product, and ensure spectacle arms do not interfere with the 

faceseal.

 (Insert Warning Triangle> 

Refer to TR-802E Powered Air User 

Instructions if intend to use these products in flammable or 

explosive atmospheres.

Materials which may come into contact with the wearer's skin are 

not known to cause allergic reactions to the majority of individuals.

These products do not contain components made from natural 

rubber latex.

PREPARATION FOR USE

Respirator systems are intended to help reduce exposures to certain 

contaminants and should always be handled with care and fully 

inspected prior to use.

Check apparatus is complete, undamaged and correctly assembled. Any 

damaged or defective parts must be replaced with original 3M spare 

parts before use. Undertake pre-use checks on Fullface or Half Mask 

and TR-602E/TR-802E Powered Air Turbo as outlined in the appropriate 

user instruction.

Breathing Tube

Inspect the breathing tube for tears, holes or cracks. Bend the tube to 

verify it is flexible. Inspect the two bayonets that connect to the Fullface 

or Half Mask for damage. Ensure two gaskets are present at the end of 

the breathing tube that connects to the TR-602E/TR-802E Powered Air 

Turbo (see Fig 1), and ensure they are not damaged. The breathing tube 

should fit firmly into the Powered Air Turbo and should attach securely to 

the Fullface or Half Mask.

Airflow Check

Note:

 The TR-973 Airflow Indicator 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 TR-973 Airflow Indicator, 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 TR-973 Airflow Indicator installed. Tight-fitting mode is indicated 

on the Powered Air Turbo when the Facepiece icon is lit (see Fig 2). The 

Powered Air Turbo is pre-calibrated to ensure the required airflow is 

provided. It also compensates for changes in air density, which is 

affected by elevation (height above sea level) and air temperature. 

Before use, undertake airflow check using the airflow indicator tube as 

shown in Fig 3.

Insert the TR-973 Airflow Indicator into the outlet of the Powered Air 

Turbo and switch on by pressing and holding the power button for 1 

second. Allow the Powered Air Turbo to run for 1 minute to allow the 

airflow to stabilise.

With the airflow check tube in the vertical position, ensure that the 

bottom of the floating ball rests at, or above, the minimum flow mark for 

the 'letter' representing your 'zone' (see Fig 3). To determine your zone, 

you need to know the elevation and temperature for the environment 

where you are conducting the airflow check. Find the zone where your 

elevation and temperature intersect on the chart shown in Fig 4.

Alarm Check

Perform alarm check as outlined in the TR-602E/TR-802E Powered Air 

Turbo User Instructions.

OPERATING INSTRUCTIONS

Fullface/Half Mask to breathing tube assembly

1. Align the two branches of the breathing tube over the two bayonet 

mounts on the Fullface/Half Mask. Ensure the one small slot on the 

breathing tube bayonet aligns with the one small lug on the Fullface/Half 

Mask 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 Fullface/Half 

Mask.

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 and 6 for Half 

Mask, Fig. 7 and 8 for Fullface Mask).

Donning - Half Mask

1. Lift the Y-branches of the BT-60 Series breathing tube along with the 

Half Mask over your head so the faceseal of the Half Mask 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.

2. Place Half Mask over your mouth and nose, then pull head harness 

over crown of your head (Fig. 9).

3. Take bottom straps in both hands, place them on back of your neck, 

and hook them together (Fig. 10).

4. Position Half Mask low on the bridge of your nose for optimal visibility 

and best fit.

5. Adjust top straps first (Fig. 11), then lower neck straps by pulling on
