The Petzl MAESTRO handle has a small hole for attaching a cord (e.g. AIRLINE cord).
Warning: any excessive pulling on the handle can cause an uncontrolled release.Verify that no external object could accidentally pull on the cord.
WARNING: use only a lightweight cord to operate the handle. In certain situations, a cord that is too heavy could impede the automatic return of the handle (AUTO-LOCK).
Note: it is not possible to use the MAESTRO’s external brake when using a cord for remote control. Make sure that the load can be controlled without passing the rope over the external brake.
To maintain proper control over unlocking and descent speed, always hold the brake-side rope and the cord in the same hand.
