Manual RHGSE Operation and Maintenance Manual
Caution: The load cell attachment bolt should not be loosened or adjusted as this will disrupt
the zero and span adjustments that were made at the factory. Should the load display require
adjustment please see section 7.16 for detailed instructions.
6.9) Setting Swivel Locks
The system is supplied with locks to prevent the front wheels from swiveling. The swivels
should be allowed to rotate for moving the RHGSE around the hanger and aircraft and then locked
once the RHGSE has been positioned under the rescue hoist cable. To lock the swivels once the
wheels have be positioned, rotate the ring to a horizontal orientation and engage the detent on the
wheel with the pin. To unlock the swivels pull the ring out of engagement and rotate the ring to a
vertical orientation.
Locked position
Note: When using the MagSens system the swivel locks should be in the unlocked position to allow
the RHGSE to center itself under the hoist and thus prevent any fleet angle during the checking of the
cable.
6.10) Replacement of the Lubridryer pads
The lubridryer pads are replaced by removing the four thumbscrews, removing the bushings by
lifting them up, and removing the old lubridryer pads by sliding the pad up the slot and installing new
pads by sliding the pad down the slot.
