environmental and safety representative to determine the suitability of the mask for the task in
question.

The product does not supply the user with oxygen. Only use in ventilated areas with an adequate
supply of oxygen. Do not use the dust filter mask if the oxygen content is below 19%.
•
Do not use the mask when the concentration of harmful substances entails an immediate hazard to
health or life.

Leave the work area immediately and seek fresh air if (a) it becomes difficult to breathe or (b) you
become dizzy or experience other discomfort.

been used once.

OPERATION

Hold the dust filter mask in your hand with your fingertips on the nose section. Allow the neck
straps to hang freely from your hand.

nose.

Only for dust filter masks with adjustable neck straps: Hold the dust filter mask in place and tighten
by pulling the tab on each neck strap. Open the buckle by pushing out the rear of the buckle.
5.
Press the soft nose section so that it fits tightly around your nose.
6.
(a) Testing dust filter masks without exhalation valve: Cup both hands over the dust filter mask and
breathe out with force.
