Respirator Assembly

Before assembling this respirator, read the warning labels
on the inside of the respirator cape and the helmet shell and
this manual in full.
Remove and read the warning card inserted between the
respirator's two lenses.

Sizing the Headband

Before you can size the headband suspension, the cape
and headband must be removed from the helmet using the
following steps:
1. Open hinged window frame by lifting up on window latch.
2. Remove cape from helmet by lifting up on clamp and
disengaging cape from helmet groove (Figure 4).
3. Turn helmet upside down. To remove inner shell from
helmet, hook index finger into loop on back of inner shell.
Press thumb against helmet rim and pull loop toward front
of helmet, then pull up and away from helmet (Figure 5).
This releases inner shell.
4. To change the headband size, unlock the four pins from the
sizing 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 6).
5. Remove headband from your head.
NOTE
If using the optional 88VXRT ratchet headband,
refer to the instruction sheet provided with the
88VXRT.
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).
