6.11) Lubrication of cable
NOTE
Use oil only as per the hoist manufacturer's recommendations.
The Lubridryer includes a reservoir that can be filled with oil. The reservoir can be used to store spare Lubridryer
pads. The Lubridryer includes a valve that shuts off the flow of oil when not in use.
When oil is added to the reservoir and the valve is open the oil seeps through a small hole to lubricate the rear
pad. The front pad should be soaked in oil before installing it, open the oil reservoir and dip the pads into the oil
filled reservoir. Therefore, it is recommended to always keep a spare set of pads in the reservoir of oil to use as
the next set. Wipe excess oil off of the frame and use a clean cloth to keep the oil off of the capstans when the
RHGSE is not in use.

6.12) Performing a fresh water wash
Fill the rotating tub ¾ of the way with fresh water and extend the cable all the way down. Using a hose, rinse off
the helicopter hoist and the cable between the helicopter hoist and the rotatub. If shop air is available, attach an
airline to the Lubridryer via the quick disconnect nipple supplied with the RHGSE. Run the
(See section 6.13)
hoist in the up direction with the load brake applied. Before operating with water rotate the load adjuster counter
clock wise to reduce the load to approximately 100 lbs. carefully observe the cable at all times on the capstans.
Retract the entire cable out of the Rotatub, and position the drum so that the plug is above the hole in the frame
then remove the plug at the bottom and drain into an approved drain.
