Fit the SR900
Sling the lower neck strap around your neck.
Hold the mask up to your chin.
Cup the mask up, until it covers your mouth and
nose.
Hold the mask in position, pull the upper head
harness up and over your head. Make sure the
upper strap sits on the crest of your head.
If necessary, unlock the buckles at your neck and
tighten or loosen the tension of the strap.
Even out the tension of the head harness by
hooking your fingers around the LOWER strap
and pulling outwards a few times. This will
increase the lift of the upper strap, supporting
the weight of the filter.
IMPORTANT
:
Never pull the head harness over a hard hat, ear
muffs, goggles, cap or other head gear – the
harness must be fitted DIRECTLY on your head.
