adjusting and installing Headband
Suspension in Hood
(If using 20TICH or SICH models, see page 10.)
To change the headband size, unlock the four pins from the siz-
ing holes. Place the headband on your head. Pull down, allowing
headband to expand until it feels comfortable. The headband will
automatically adjust to your size. Lock into place by pushing the
four pins into the sizing holes (Figure 4).
Note
If using the optional 20RT ratchet headband suspension,
refer to the instruction sheet provided with the 20RT.
adjust Crown Straps for Vertical Fit
To improve suspension comfort, adjust crown straps vertically by
repositioning the crown strap posts in the crown straps. Vertical
adjustment makes the headband ride higher or lower on the
wearer’s head. To adjust, push crown strap post from slot, move
to new slot, and snap in to secure. Move key to desired vertical
position. Repeat for other crown strap post (Figure 7).
Note
20LF and 20LF2 series loose-fitting facepiece hoods have a
sewn-in headband.
Note
If the hood rises off your head during use, first verify
proper air pressure, then select a different hood for your
application, or use the optional chin strap.
