4. CONTROL
Visually and mechanically check the equipment's functions before use.
Check the following details visually:
– Check the line along its entire length. It must not show chafing or varying thickness
(10 mm). It must not show signs of major stress, such as frayed cuts, change of
shape, stiffness or other deformation with permanent kinks.
– The equipment and karabiner must be in their original state. No cracks, deformations,
significant wear marks or limited functions.
Check the following details mechanically:
– Pull the line through the device – three metres in each direction finishing off with the
"rescue" line's karabiner approx. 30 cm from the device (NOTE that the brake force
must increase with increased pulling power on the line).
– All moving/locking parts must show perfect function.
When used, the equipment must always be inspected by a CRESTO certified individual.
Faulty equipment, lines or components must never be reused. If the equipment is found to
be faulty during inspection, the component(s) must immediately be returned to a CRESTO
certified individual for further inspection. The inspection must be performed by a certified
expert with a minimum competence of a certified competent person.
The equipment must be inspected and checked at least once every 12 months. The inspec-
tion must be carried out by the manufacturer or an individual approved by the manufacturer
to carry out inspections and repairs.
NOTE: Several countries require inspection at 6-month intervals.
WARNING! Alteration or replacement of any of the equipment's components outside the
scope of equipment certification and this guide is strictly prohibited!
