(1) This product is classied as a rock climbing and mountaineering helmet. It cannot be used for any other kind of sport.

headband adjustment should be inspected. We recommend a thorough inspection at least once a year by a competent person (this
may be the manufacturer). This inspection should be recorded on the inspection form supplied.
(3) Lives depend upon your equipment. The user should be fully aware of its history (use, storage, inspection etc.). If this equipment
is not for personal use (e.g. used in mountaineering centres) we strongly recommend a systematic approach to record keeping.
This should always be carried out by a competent person.
