Use in the 'power-off' state is not normal, little or no protection is provided and a
build up of carbon dioxide and depletion of oxygen within the Headtop may occur,
vacate the contaminated area immediately.
Take care to prevent the breathing tube from becoming looped around protruding objects.
If during use, the airflow into the Headtop stops and the alarm sounds, vacate the
contaminated area immediately and investigate the cause (please see fault finding).
The 'in-use' life of the product will vary with frequency and conditions of use.
In everyday use, it is recommended that the product is discarded after approximately 5
years service, provided the product is stored and maintained as stated below.
Some extreme conditions may result in deterioration over a shorter period.
Note: Do not expose battery pack to temperatures above 54°C. The Powered Air Turbo
battery alarm will activate if battery pack temperature reaches 60°C while the Powered Air
Turbo is in use.
Do not use the batteries outside of the recommended temperature limits.
DOFFING

3. Unbuckle the waist belt.
For long-term storage of filters, remove the filter and seal in a closed container. 3M does
not recommend the filter be left in place in the Powered Air Turbo as damage may occur
to the filter gasket.
NOTE If the respirator has been used in an area that has caused it to become
contaminated with a substance requiring special decontamination procedures it
should be placed in a suitable container and sealed until it can be decontaminated
or discarded.
