Manual RHGSE Operation and Maintenance Manual

Do not operate the RHGSE with a new cable more than three evolutions before relieving the twist from the cable

by extended the cable in flight; otherwise, the cable will acquire additional twisting and damage to the equipment

and cable can occur.

Retracting with the motor drive engaged may damage the electronic control assembly.

The RHGSE uses a Brake Band and Brake Drum to generate the load in the cable in the retracting direction.

The Brake Band and Brake Drum will get very hot. The RHGSE should not be used more than three times

consecutively without letting the Brake Band and Brake Drum cool down.

The RHGSE is not to be used excessively at high loads without flying the rescue hoist and extending the cable

as part of normal operations. Excessive use of the RHGSE without extending the cable in flight traps the

Stop running immediately if the RHGSE lifts off the ground and adjust clutch as required.

When starting to reel in the load, the Brake Handle must not be fully applied with the load adjusted to the

maximum; this is because the coefficient of static friction is greater than the coefficient of dynamic friction. If the

Brake Handle is fully activated before starting, the RHGSE will be lifted off of the ground and may cause

damage to the hoist, aircraft or to the operator. If the system does lift off the ground unexpectedly stop lifting with

the rescue hoist and lower the system to the ground and release the Brake Handle. Never try to lower the

system by releasing the Brake Handle when the system is off the ground.

Failure to stop the hoist before the hook comes out of the Rotatub may cause damage to the RHGSE and the

cable. Pay close attention to the number of turns in the Rotatub as the hook approaches the up limit position.

If the Cable is not wrapped tightly around the capstans it may loosen up and come off the capstans.

Ensure that the exit and pressure tensioner rollers are engaged when extending or retracting the cable.

Ensure the cable enters the bottom of cutout in the Spooler at the base of the Rotatub or the cable may start

wrapping too high on the Spooler and not have enough space to wrap the entire length of cable.

When retracting cable after unwinding it from the capstans use caution to prevent the cable hook from getting

entangled on the tensioner arms. Sever damage to the arms or cable may result.
