Belay devices must only be used as shown in Figures A and B. Any other application could be dangerous.
The belay device should only be used with screw carabiners (or other lockable carabiners).
Always check that the carabiner is correctly locked and attached to the belay loop.
Place the rope around the belay device as shown in Figure A. This technique can be used with both single and double rope lines.
Proceed as shown in Figure B for abseiling.
Thin ropes reduce the braking effect. We recommend you use self-belaying when abseiling (using a prussic knot or another reliable technique).
