FUNCTIONS
To control the device in descent, your left hand is used to position the handle, and your right hand is used on the trailing length of rope to give you extra security and fine adjustments of speed control. If in the situation that you pull the handle too far the device will stop. To reset the device rotate the handle clockwise, in the direction of the arrows. This will allow you to continue to descend. All rope adjustment devices create heat when travelling along rope at speed, which can cause damage to the rope. Always check the rope for damage as well as the device.
