Fix one end of the rope to an anchor point. Install the other end of the rope in the GRIGRI, making sure to put it into the device in the right direction. Connect your GRIGRI to a second anchor point with a locking carabiner. Lock the carabiner. Do a function test as indicated in the Instructions for Use. Tension the rope by removing all slack. The tyrolean must be hand-tensioned by one or two people, using a simple pulley system. Note that the shorter the tyrolean, the harder it is to correctly tension the rope.

WARNING, once the rope is taut between the two anchors, you must secure the GRIGRI by tying-off the rope up against the GRIGRI.

WARNING, a tyrolean creates a very high load on the anchor points.

Make sure the anchor points are sufficiently strong.

Falls are prohibited on tyroleans.

WARNING, overloading the tyrolean can completely lock the GRIGRI onto the rope, making it difficult to unlock. The GRIGRI is not covered under warranty if you break the handle because your tyrolean is too tight.

Tip for unlocking: make a simple haul system as indicated in the drawing. Pull on the free end to create slack between the ascender and the GRIGRI. Pull the handle.
