Press and turn the ratchet knob clockwise until a
secure and comfortable fit is achieved. When
removing, if necessary press and turn the ratchet
knob anti-clockwise to loosen the headband.
Adjust the height of the visor as follows:
■
Remove the Airshield.
■
Press the stud through the hole on top half of
headband.
■
Slide the lower half to increase or decrease
the height.
■
Re-fasten headband by pushing the stud
through the nearest hole and check the height
of the visor when worn.
■
Repeat above until a correct fit is achieved.
Ensure that the unit is pivoted down
fully so that the headband stops are
against the main fan housing. The
plastic headband lugs are designed to
limit the movement of the visor to the
face.
Adjusting the height will affect the fit around the
chin.
Adjusting the face seal will affect the fit at the
sides.
Ensure that the face seal around the chin and
sides is pulled rearwards such that the seal
deforms away from the frame and visor and not
towards it.
Check the fit of the face seal in a mirror and/or
run a finger around the line of the face seal to
ensure contact.
OPERATION
The switch (A) operates the fan-motor unit (B),
powered by rechargeable battery pack(s) (C),
which draws air (D) through the pre-filter (E) to
remove larger particles of dust before being
drawn through the main filter (F). The filtered air
(G) is passed down over the face. Exhaled
breath (H) leaves the respirator through holes in
the bottom of the visor frame.
If protective clothing is worn,
ensure the bottom of the visor is not
obstructed.
