OPERATION:
A. Vertical Descent:
Step 1.
Open protective cover or enclosure,
attach Rescumatic® to anchorage and
drop spool to safe level. For systems
250 feet (76.2m) and over, or if spool
can not be dropped, attach rope spool
to rotating spindle. See Figure 9.
Step 2.
Put webbing body support over head
and under arms, adjust support buckle
to tighten. If full body harness is
available, don harness per manufacturer’s instructions and secure harness to D-ring on body support
using carabiner. See Figure 10.
Step 3.
Pull on free end of rope to take up slack. See Figure 11. Rope must be taught before descending.
Step 4.
Slowly step off of the platform to begin descent. See Figure 12.
Step 5.
Descend to safe level. Prepare for landing by bending knees. See Figure 13. Disconnect from system.
Body support at opposite end of system should now be located near Rescumatic® unit, available for
second descent.
If the system is to be used for multiple descents, the second person shall repeat steps 2 - 5.
