7.3 Changing the face seal

The face seal should be changed when necessary, using the following procedure:
1. Remove the silver-coloured front from the welding head top.
2. Squeeze the clamps together and press down the plastic strip, which is sewn to the face
seal, through the helmet shell and remove the old face seal, figure 12.
3. Install the new face seal by fixing the plastic strip to the air deflector, as in figure 13.
NOTE! The face seal must be between the head top shell and the plastic strip.
4. Press the latch on the plastic strip up through the head top shell, figure 14, and check that
the pins on the head top shell are fixed in the two holes in the plastic strip, figure 15.
5. Continue installation by fixing the plastic strip along the sides of the head top shell, so that
it is locked mechanically between the head top shell and the half-moons on each side,
figure 16.
6. Lock the face seal by clamping the plastic strip with the silver-coloured front.
7. Adjust the face seal as in the "FITTING" chapter, to make it rest against your face with a
comfortable pressure on your temples.
