8.5 Replacing the inner collar (nylon and ASS cape only)
The inner collar is important in ensuring the air circulation inside the helmet and preventing the ingress of
dust. Detach the collar from the cape using the zipper to replace or wash (see also 9.2 for washing in-
structions).
The inner collar must be replaced if it no longer fits snugly round the neck.
8.6 Replacing the lens frame
The lens frame must be replaced if the seal is no longer guaranteed. The sound insulation inside the
helmet should also be replaced when replacing the lens frame.
8.7 Replacing the chin strap
Replace the chin strip when it becomes worn.
Push the chin strap upwards until it snaps out and then remove it from the holder. When fitting the new
chin strap, ensure that the bevelled edges of the holes are facing inwards.
9 Servicing / Cleaning
Do not use aggressive chemicals or solvents to clean the equipment. These may irritate or harm
the operator and alter the properties of the material used.
9.1 Filter
The filter (foam) is inside the control valve. It must be removed if it is soiled. Use a small screwdriver to
prise off the snap ring and remove the screen filter and the soiled foam filter. Reassemble the compo-
nents in reverse order.
9.2 Nylon cape
The cape can be machine-washed in warm water using a mild detergent. It can be dried in a tumble dry-
er at the lowest temperature setting. Do not dry clean. See 8.4 for how to detach the cape.
9.3 Leather cape
The cape can be brushed or cleaned with a damp sponge. (Do not wash, dry clean, iron or use chlorine
bleach.)
9.4 Inner collar
For reasons of hygiene, the inner collar should be washed daily to remove sweat and dust.
Detach the collar from the cape (zipper) and wash in warm water and a mild detergent. The collar can be
dried in a tumble dryer at the lowest temperature setting. Do not dry clean the collar. See 8.5 for how to
detach the collar.
9.5 Sweatband/helmet suspension
The sweatband, helmet suspension and chin strap can be washed in warm water and a mild detergent.
See 8.3 for how to detach the helmet suspension.
