Page 4: Release Handle
THE MPD The MPD is designed for use with static or low-stretch kernmantle life safety rope. Use only rope that has been inspected, is of proper size and is in good condition. The user should be aware that environmental conditions may have an effect on the rope’s interaction with the MPD. - Page 5 As with all new rescue equipment, the MPD should be thoroughly inspected before being placed in service. The MPD is a robust unit but should still be inspected after each use to ensure that damage did not occur. When inspecting, look for any damaged, dirty or sticking components, excessive wear or any other factor that may prevent proper function.

Page 6: About The Mpd
MPD is rigged as a ratchet or progress capture in a pulley system. For example, once the rigged MPD is connected to the anchor, for safety, lock the Parking Brake until you are ready to use the device. - Page 7 ROTATE BACK PLATE REVIEW DIAGRAM FULLY OPEN FOR PROPER LOADING Anchor Running End Running End Load End Load End INSERT CLOSE AND SECURE ROPE BACK PLATE Parking Brake must be unlocked to load.

Page 10: As A Descent Control Device
As the rescuer or rescuer and patient approach the edge, it is very easy to take in rope through the MPD to prepare for the edge transition. Pretensioning of the Main Line is also simplified because of this. - Page 11 Begin lowering by rotating the handle slowly counterclockwise all the way to completely unseat the Moving Brake from the rope, controlling the rate primarily with friction on the Fixed Brake V-Groove. Maintaining the “S-shaped” bend in the rope will improve the function of the braking mechanism in the event it is needed and will increase the service life of the Moving Brake, reducing the potential for rope creep through the device.
- Page 12 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. Pull up to engage the...

Page 13: To Stop Lowering
FOR HEAVY LOADS Add additional friction by threading the rope over the Secondary Friction Post. Load 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. -
Page 14: Using The Mpd As A Belay Device
AS A BELAY DEVICE The MPD is designed to be used as a belay device to arrest a falling load should the Main Line system fail. It is recommended that during edge transitions, while either lowering or raising loads, that the Belay Line tension be kept hand tight and without slack in the line. - Page 15 Therefore, in a Shared Tension lower it is imperative that the running end rope of the Belay Line be held back toward the anchor, maintaining the “S-shaped” bend as the rope runs through the MPD. If there is a sudden change in speed or tension on the rope running through the MPD,...
- Page 16 The other hand feeds the running end into the MPD so that the rope is unseated from the sheave tread . This will reduce rope drag on the sheave and keep the MPD from inadvertently locking up.

MPD. This way either rope system can perform either function, without the need for complex changeovers or function specific equipment. Additionally, if an MPD is used for both the Main Line and Belay Line in a Shared Tension System, then should either of these systems fail, the other rope system can serve as a belay and the potential arresting distance is minimized since both ropes will be prestretched. -
Page 18: Mechanical Advantage System
IN A MECHANICAL ADVANTAGE SYSTEM The MPD is designed to function both as a pulley and as a ratchet or progress capture device in a M/A system. After lowering, there is no need for a complex changeover between a lowering system and a raising system. -

Page 20: Inspection And Repair
Each user should be trained in equipment inspection and should do a cursory inspection before each use. The MPD should be inspected after each use to ensure that damage did not occur. When inspecting, look for any damaged, dirty or sticking components, excessive wear or any other factor that may prevent proper function. -
