Manual RHGSE Operation and Maintenance Manual
6.5) Actuating the Brake Handle
When reeling out the Brake Handle must be in the released position and when reeling in the crank handle
should be disengaged and the brake handle must be in the applied position to apply a heavy load to the cable.

6.6) Running the rescue hoist in the down direction (extending)
Before extending, verify the cable is properly installed on the RHGSE, the cable is wrapped tight on the
capstans, and the cover is closed and latched.
With one hand operating the hoist control pendant use the other hand to engage the slots in the handle with the
pin on the shaft to rotate the crank handle in the clockwise direction to develop a small load in the cable. Actuate
the pendant to start the hoist running in the down direction. Start cranking slowly and observe the cable to
ensure it is completely seated in the capstan grooves. If it begins to loosen on the third groove of the top
capstan, stop and pull the cable down into the capstan groove and then continue. Run the hoist in the down
direction at a speed that allows you to observe the hoist while cranking in the clockwise direction comfortably.
Do not allow the cable to get loose while extending.
Extend the cable completely; always paying careful attention
to the helicopter hoist and to the condition of the cable. If the
cable snags in the Lubridryer pads for any reason such as a
kink or a broken wire or broken strand; the cable will loosen
between the top of the Lubridryer and an increase in crank
resistance will be felt. In this event, the cable needs to be
replaced; run the cable out into the drum and follow the
manufacturer's instructions for replacing the hoist cable.
Absent any deficiencies noted during inspection, run the hoist
in the down direction until the helicopter hoist is stopped by
the full out limit switches.
6.7) Running the rescue hoist in the up direction
(retracting)
The wheel brakes on the RHGSE should be unlocked to allow
the equipment to center itself under the hoist.
