PREPARING TO LOWER

Firmly grip the running end of the rope and apply friction over the Fixed 
Brake V-Groove, bringing the rope back toward the anchor and parallel to 
the load end, creating an “S-shaped” bend in the rope.

TO LOWER

Unlock the Parking Brake. Grasp the Release Handle and pull up to  
engage the release mechanism (

1

) and then rotate counterclockwise  

to lower (

2

). Rotating the Moving Brake off the rope may significantly 

increase the service life of the MPD.

FOR HEAVY LOADS

Add additional friction by threading the rope over the Secondary Friction Post.

TO STOP LOWERING

To stop lowering and lock the rope, disengage the Release Handle.

NOTE

 Although there is a return spring to assist in disengaging the Release 

Handle, it is the user’s responsibility to ensure that the handle is fully 
pushed in when not actively lowering.

ALWAYS MAINTAIN A FIRM GRIP ON THE RUNNING END OF THE ROPE  
WHEN THE PARKING BRAKE IS NOT LOCKED.
