Replacing the visor
● If fitted, remove the covering cap from the drinking valve and
dismount it together with the frame.
● Loosen the screws (Figure F-1 on Page 3) and remove the rotary
knob.
● Unhook the cap from the visor frame. If a drinking valve is fitted,
remove the cap from the connection piece by pulling it away from
the drinking valve.
The drinking valve remains in the connection piece.
● Remove the screws from the visor frame (Figure G on Page 3).
● Spread the visor frame, tilt it towards the front and pull apart
sideways.
● Detach the visor from the rubber frame.
NOTICE
Moistening either the facepiece body or the visor frame facilitates
the assembly of the visor.
● Insert the new visor in the visor frame: Align the center marking of
the visor and the center marking of the facepiece body. Make sure
that the visor is properly seated in the facepiece body.
● Apply pressure onto the visor frame until it snaps into place at the
center of the visor, then tighten with new self-locking screws until
the gap is closed.
If the old screws are used again, they must be secured with
Loctite 221.
● Align the wiper: The wiper arm must be in the center of the visor
and the wiper must be correctly put on the visor after the
assembly.
● If fitted, adjust the drinking valve.
● Hook the cap into place on the button. If a drinking valve is fitted,
pull the cap over the drinking valve. Hook the cap into the visor
frame.
