Ascending

1. First attach the back-up device to the safety rope.
2. Attach the chest ascender to the working rope.
3. Attach the handled ascender and foot loop to the working rope above the chest ascender.

The cycle

1. Stand in the foot loop so that the handled ascender is weighted and the working rope will ride through the chest ascender. If the rope drags through the chest ascender, hold the rope coming out of the bottom in your hand or grip it between your feet. Sit back and rest on the chest ascender again.
2. Lift your feet and move the handled ascender further up the rope.
3. Repeat by standing up in the foot loop attached to the handled ascender.

Back-up device position

The back-up device should be kept as high as possible (in all cases above waist height) on the safety rope throughout the ascent — to help minimise the fall distance should the working rope fail.

The technique used for moving the back-up device should not affect the operation of the device.
